Decorative and Industrial Purposes
Plating is a process used for a large variety of materials, in various applications, including those related to industries from aerospace, to medicine, electronics and many others.
Electroplating used for various types of decorative finishes, includes:-
• Gold and Silver plating
• Nickel and Tin
A Form of Artwork
Plating is an innovative process involving items of small and medium sizes and those of a classified delicate form. Traditional methods of plating include the recognized “barrel”, “rack”, and others, developed to meet the special needs of customers. Establish plating services, use control methods applying statistical processing and tooling, which ensures their finished products are of a consistent quality.
The aspect of top quality, supported by competitive pricing is a factor in this service industry.
Skilled Crafts persons for the Right Plating Finishes
Flexibility by a plating service is necessary, to meet the sometimes-unusual requirements of customers. In some instances, the artisans need innovation in skills and tools, to provide specific metal plating, combination finishes.
Finishes in metals for example, electroplating on gold, require varying levels of hardness for constant coverage, which involve original heating and baking processes.
The covering or depositing of a conductive surface, classified as a plating process, is one that has been practiced for many hundreds of years. It is now a crucial process in the modern technological world of today.
The process is used for the decoration of various items, such as:-
• Corrosion inhibition
• Soldering improvement
• Hardening and wear improvement
• Friction reduction
• Conductivity and Radiation shielding
It is possible for the depositing of a thin-film, on objects such as atoms, which enables use of the process in nanotechnology.
Various Plating Techniques
There are variations of nonstick plating methods, including the covering of a solid surface with a metal sheet. The application of heat and pressure fuses them, for example as in “Sheffield Plate”.
Among other techniques used in the plating process, is vapour deposition under vacuum. The term plating, often used in reference to the use of liquids and “Metalizing” is a reference to the coating of non-metallic materials with metal.
Electroplating is the application of electrons to an ionic metal, which forms a non-ionic coating. There are various methods of achieving this, including involvement of a chemical solution with the ionic form of the metal.
This is a term also known as “Electro-less Plating” and is a non-galvanic method of plating, involving various and simultaneous reactions within an aqueous solution. The reactions occur without any external power usage and are the result of hydrogen released by a reducing agent.
The “Electro-less” plating method is usually applied in processes related to nickel plating. However, silver, gold and copper covering is applicable by this method.
Silver or Gold
Within the field of electronics, less demanding, plating applications use silver, as an economical gold replacement. Silver does have a greater conducting ability, but a factor related to it is of oxidization. Therefore, gold is preferred plating relative to “contact” points.
In environments with a high humidity factor, care should be used I the case of any exposed parts. Should the layer of silver plating be porous or cracked, the copper surface will undergo galvanic corrosion.
Touch of History
In days gone by, silver plating provided a cheap method of presenting items, instead of producing them in silver, for example, cutlery and candlesticks. Reputedly, the earliest recorded version of this, related back to Sheffield Plate. Reports show that the nineteenth century saw the introduction of various new methods of plating, including that of electro-plating.
