Metal plating is a specialist process that involves adding a thin additional layer to the surface of a metal object. It comes under the category of ‘surface treatments’. The purpose of plating is to add new, or enhance existing, desirable attributes. Within this process, the object being plated is usually referred to as the “substrate”. So what are the key benefits?
Increased Durability
When a substrate is plated, its hardness and strength both increase. This improves durability and robustness and increases its overall lifespan.
Chrome plating and copper plating are both used for this purpose in numerous industries. Metal plating is an excellent way of restoring/reinvigorating an old part or adding extra protection to a new one.
Aesthetic Appeal
Plating a substrate can significantly enhance its appearance. Notable examples include jewellery, where a gold or silver plating is a common addition, and automotive parts, which are often given a chrome plating to achieve a shiny finish.
Better Heat Resistance
Metal plating, and in particular silver-plating, is able to increase the heat resistance of substrates. This is very useful for parts/components that will be exposed to high temperatures, such as those used in automobiles and aircraft.
Metal Plating Techniques
There are several different techniques used for metal plating, with the most-popular being electroplating, electroless plating and immersion.
Electroplating relies on electrolysis and uses a special electrolytic bath. Electroless plating, in contrast, doesn’t use an electrical current. Immersion is a simpler method that uses a solution of metal ions.
Metal Plating Experts
If you feel that your business could benefit from metal plating, there are several specialist companies such as https://www.swmf.co.uk/surface-coatings/zinc-nickel-alloy-plating/ who offer zinc nickel plating and a number of other options.
Increased Electric Conductivity
Metal plating using copper, gold or silver can boost the electrical conductivity of raw metal parts. This is useful in electronics in particular, as it can ensure reliable connections in electronic circuit boards.
The metal plating process offers plenty of benefits: notably the ability to increase the lifespan of metal parts.
