How the Industrial Silver Plating Done

Industrial Silver Plating is done by simply dissolving the subject that is to be plated to an electrolyte. Afterwards, the current is then passed on from the cathode of an electrolyte cell down towards the anode, which often comes in the form of a silver object. The positive silver ions would then flow towards the cathode from the silver cyanide wherein they will be neutralized and then be attached towards the object that is being plated, such as the silver metal. The anode bar will then lose the electrons in order to become silver ions until such time that it dissolves. On the other hand, the silver metals are then transferred towards the cathode. Such process will go on until such time as the desired texture will be achieved right on the cathode. And that is how the Silver Plating is generally done.

Introduction

As the famous saying goes, “all that glitters is not gold”, which indeed is really true, because silver is another metal that is known for its beautiful glitter. But have you ever wondered what makes the silver to shine beautifully? Have you ever thought how come the silver metal would sometimes appear very realistic and new despite of it being used for quite some time? Well the answer is simply because it has gone through Silver Plating. Although several other techniques and compositions are being used for this kind of plating today, not to mention the use of modern equipment, the rationale behind all these processes is still the same.

Definition

There are various techniques that are involved with Silver Plating and in most cases, it makes use of electroplating. The Silver Electro Plating is often applied when there is a need to deposit a layer of silver on a glass, porcelain, china and other types of metals, which comes in different thickness, giving them to have a lustrous glitter and a more beautiful finish.

Considerations

Even though Silver Electro Plating is among the most popular techniques applied when it comes to Silver Plating, the compositions as well as the techniques needed for this process will greatly vary, depending on the nature and the type of materials involved. Although silver might be able to blend well with the surface of various metals, it might not do the same thing for other metals. Thus, before you employ Silver Plating, make sure to familiarize the metals or items to be used and which of these cannot blend with silver. A highly skilled silversmith is certainly very familiar with this.

Requirements

In order for Silver Plating to be done, there are various items needed – old or worn out silver jewelry as well as an effective jewelry cleaning solution. Class crucible that contains silver particulates in the form of a positive ion, cathode and electrical terminal is also needed for the procedure. The process would require cleaning jewelry thoroughly so as to remove any dirt or grease on it and in order for the silver to be able to blend well with metal.

Tin Plating Basics

Soldering is a process in which two metals are enjoined by a filler metal (solder), effectively promoting electrical conductivity. This method has been used for a long time, with high reliability, low risk of failure and ease of use. Soldering is mainly used for manufacturing integrated circuits that we can find in every electronic device. Embedded in the IC is the PCB, or Printed Circuit Board, where different electrical components of electrical devices are bound together.

To be able to be soldered into the PCB, an electrical component (e.g. Wires) have to be coated with the soldering material, in order to adhere to the board. Solder plating, or Tin-Lead plating is the process in which the material to be soldered, in this case, the wire, is plated with Tin-Lead solder before soldering it to the PCB, so as to assure complete adhesion to the PCB, and eliminate crevices that will later encapsulate heat in the solder and increase the chances of material failure.

The main function of this process, aside from complete adhesion is to protect the electrical contact from oxidizing, which further leads to corrosion. Tin plating has been used widespread; however, whiskers, or small tendrils or flashes of Tin become present in the solder that is one of the causes of short-circuiting in electronic devices. Tin-Lead has been introduced in order to avoid this phenomenon, where Lead is used to control the splatter of Tin in the solder.

There are different types of Tin-Lead coatings, according to ratio, but only 3 ratios are being considered: 60/40, 90/10 and 95/5. The ratio of Tin-Lead only depends on how much stress electrical components are experiencing, so, the higher the thermal and electrical stress, the higher amount of Lead is needed.

One can also distinguish the amount of Lead present, as 95/5 Tin-plate coats have matte finish, while higher Lead contents develop a bright and shiny finish.

Tin-Lead thin film deposition is also widely used because of its ability to be deposited to both ferrous (compounds that contain Iron) and non-ferrous (compounds not containing Iron), which makes it more economical for IC manufacturers.

Plating processes include Vapor Deposition, ion sputtering and Metallization. Vapor deposition deals with the atom by atom application of coats, under sub-atmospheric conditions (i.e. Vacuum). Thickness of application range from 1 atom so millimeters, depending on exposure to vacuum, and it can also be used to apply different layers at a time. Sputtering involves a target and a source, where ions from the source are bombarded to the material substrate, generating adhesion by immense pressure and elevated temperatures.

Metallization is the general term encompassing the different processes in material plating. Some of its processes are Vacuum Metalizing, where metal coat is heated to its boiling point, and letting condensation deposit the metal to the substrate surface, and Thermal Spraying, where metal coating is put to elevated temperature before application. Vacuum metalizing produces thicker and better yields than thermal spraying because of the presence of vacuum, that prevents outside contamination and complete adhesion.

Industrial Electroplating Options

There are various types of industrial electroplating such as gold plating, silver plating, nickel plating, etc. based on the type of metal that is being plated or based on its application, a specific type of plating is used. Not just the cost of being a concern, a specific type of electroplating is used keeping a specific objective in mind. On this article, we will go over few basics of Industrial Silver Plating.

Industrial Silver Plating is used by various industries including electronics industry, military, aviation, automotive and several other commercial industries. Silver is an excellent metal that is highly ductile with an elegant shine and reflectivity. When it comes to electrical and thermal conductivity, silver is second to none. Whine gold plating and other plating have their own use, silver has the highest amount of electrical and thermal conductivity as well as highest level of optical reflectivity within the visible range. Some might say gold has the more reflectivity but that is within the infrared range, not within the visible range.

Due to its high temperature sustainability, silver is used to coat nuts and bearings that perform under high temperature of up to 1200 degree Fahrenheit. Pure silver is also used for soldering electrical wires as it offers great solderability and bonding. Practically all electrical circuit boards have wires soldered in silver due to its bonding and electrical conductivity.

While there are other metal electroplating options, Industrial Silver Plating is often the first option if precious metal coating is needed. The main reason for electing silver is because it is far less costly compared to other precious metal such as gold or platinum. Silver costs about one tenth of the cost of gold roughly which makes silver a good option for precious metal coating.

Aside from the cost issue, Industrial Silver Plating is used to increase the life of an item by adding a coating around the surface. Other standard coating like tin or alloy coating doesn’t increase the life cycle of the metal as much as it does with silver coating. Silver therefore is the primary choice among engineers when it comes to selecting a coating that will not only increase the product life cycle but ass a shine and increase the look of the item.

Cheapre options like tin or alloy are used for certain coatings but they do not offer nearly close amount of thermal or electrical conductivity and it is not corrosion resistant either. So when it comes to selecting a metal for its conductivity and corrosion resistance, Industrial Silver Plating is basically the primary and in some cases the only option.

Industrial Silver Plating for Better Corrosion Resistance and Electrical Conductivity

Industrial Silver Plating for Better Corrosion Resistance and Electrical Conductivity

Industrial Silver Plating is basically adding a layer of coating around an object to make it either more corrosion resistant or improve the electrical conductivity. Silver plating is also done to improve the appearance of some products by bringing out a shine and to make the product more visually appealing.

Industrial Silver Plating is a bit inferior when it is compared to gold plating, Industrial Silver Plating offers lot of the same characteristics and benefits of gold plating only at a much more attractive price point.

There are many benefits of Industrial Silver Plating. It offers an excellent coating for the solderability of small parts, offers a great coating for parts and equipment which need very low electrical resistance, and at the same time it offers excellent lubricity.

While Industrial Silver Plating is used by a wide range of industries including the military, the railway, aerospace engineering, etc, it is most ideally used by the electrical engineering industry for its high electrical as well as heat conductivity along with the lowest resistance to any metal.

It is a common practice to use silver in the wide range of communication and health care industry as silver is toxic to a lot of bacteria along with many other micro organism. Due to this toxic quality, it is widely used in the home water purification system. If you look at a standard kitchen or a bathroom in North America, you will see that all the kitchen, bathroom shower and sink water faucets and shower heads are silver. It doesn’t necessarily mean that those kitchen and batch fixtures are all made of silver. It just means that they are at the least coated with silver. The reason for using silver coating in the kitchen is multi fold. One is to make the parts corrosion resistance since they are in constant contact of water, second is to make the more healthy choice by protecting these parts from bacteria and other micro-organism, and lastly to make them look visually attractive and the Industrial Silver Plating makes these metal parts shinning.

Some of the most common industrial applications of silver plating:

•    Aerospace: fasteners (lubrication and corrosion protection), turbine fasteners & components, bearing surfaces, electronic connectors, rotorcraft gears and others
•    Electrical Components: coatings on connectors that operate at higher and less critical loadings
•    Semi-conductor Lead Frames: current bonding techniques that require a precious metal
•    Bearing Surfaces: high load applications in fluids of low lubricity

Various Types of Silver plating

Industrial Silver Plating is the method of covering a conductive later with silver to protect the metal from corrosion and at the same time adding a sparkling shine to the metal.

Silver is a precious desirable metal that is white in color and has an oxidizing property. Because of the property of high electrical conductivity, silver is commonly used in many electronics and semiconductor materials. Silver is an ideal conductor of heat for which it offers ideal solderability. It is impressionable and has a high amount of Lubricity. Silver is used in bearing surfaces and a lot of anti-galling uses. Since the silver is ductile, it can easily be moulded into any shape and is therefore used by the jewellery and flatware companies for its decorative look.

Even though silver is not a precious metal as gold, it is still considered as a semi-precious metal and is traded in the stock exchanges as precious metal just like gold.

Various Types of Silver plating

Various types of Industrial Silver Plating are used starting from matte plating to bright and semi-bright plating. Sometimes plating can be applied without Chromate and others times the process ca use Chromate. It is also permissible to use pure silver plating or electroplating with pure silver.

Industrial silver plating has more than one option

Lots of companies offer silver plating and have the technology of industrial silver plating on various types of electrical apparatus, vehicle bars and ball bearing surfaces. There are also some factories that offer corrosion resistant cyanide coating devoid of chromates for the purpose of electroplating wide range of ferrous and non-ferrous base metals.

Uses of Industrial Silver plating

The most widely used process of industrial silver plating is within the ornamentation of jewellery, dinner plates, drink cups, sports trophies and prize medals. Silver is put into high heat and the melted lava like metal is applied to coat the surface of many different items to bring out the perfect shine an appealing look.

Silver plating is widely utilized to better solderability of an electronic item by hardening the surface area and by improving the wearability. It is also utilized to protect an item from corrosion. The electroplating assists in lowering friction and to improve the paint adhesion. It is good for altering conductivity and provides a shield against radiation.

Since silverplating is a atomic deposition process, thin films of silver can be formed on surfaces.These can act as layers for additional nanotechnology.

Silver finds application in electronics as a replacement for gold. Variable capacitors with silver plated plates require silver plating.

The Process of Nickel Plating

Nickel Plating is being used for various different things. First of all, it helps to create a corrosion resistant coating that keeps the base metal protected against rusting and oxidizing. It is also used frequently for food processing in order to prevent iron contamination. The process also helps to increase the hardness as well as the durability of the mechanical parts and tools. This process of plating also allows for the soldering of even the most difficult metals. Moreover, Nickel Plating is also being used to create several beautiful decorative finishes which range from chrome like gleam up to brushed stainless steel and metallic black. It also happens that the process of black nickel plating is being used regularly on applications on aerospace. For thicker plating, this can help to make the object to become magnetic.

Different Finishes and Properties

In order to get different finishes and properties, you might have to add other metals and chemicals for your plating solution. Such chemicals can help to change the way the atoms will arrange themselves and add some other metals to be used for Nickel Plating. If you need it to be corrosion resistance, avoid adding any other chemicals on the electrolyte as this might trigger the end plating to be tarnished or to stain.

You will need to use pure nickel during the process of Nickel Plating. You may also try to remove a nickel winding from older guitar strings if you do not have enough to spend for nickel. This will take up much time, although it can be possibly done with the use of wire cutters and pliers.

Electro Nickel Plating Process

The Electro nickel plating is more commonly known as nickel electro deposition and is becoming very popular for use for various processes in different manufacturing application. The process of electro deposition makes use of an electrical current in coating a conductive material which is often made of metal and a thin layer of nickel. There are also other metals used such as stainless steel, platinum, copper and zinc.

Benefits of Nickel Electro Deposition

Generally, the process electroplating helps to improve several different characteristics of metals which are not present inherently on the base materials. Among these benefits are increased resistance to corrosion, superior strength, improved hardness, resistance to wear as well as improved ductility. Nickel is known for being useful for the process of electroplating metal due to the benefits stated above. In addition, this process of plating also helps to improve the product’s brightness as well as its external appearance. Various nickel plating chemicals are being incorporated on the process to deliver anything from semi bright as well as fully bright cosmetic effect to pearl, matte and satin finishes.

In order to transfer to the surface of the product, a negative charge should be applied towards the base material during the process of Nickel Plating. To make this possible, the product is being attached to a battery, a rectifier or other power supply by means of a conductive wire. As soon as it is attached, a nickel rod will then be connected in the same manner to a positive side of the power source.
