Among the most widely used treatments for protecting metals are electroplating (galvanic) treatments: a technology used for more than a century that improves certain aesthetic and technical properties of mechanical components.
Electroplating is widely used in precision engineering. But how does it work? Essentially, electroplating treatments are a series of operations carried out with aqueous solutions, often at or near room temperature: they contain metal salts, bases, acids and specific additives, and are carried out in tanks lined up in sequence.
As mentioned, the surface properties of the part are changed both technically and aesthetically: among other things, the treated part becomes more resistant to corrosion. This is very important, considering that every metal is subject to deterioration over time.
Electroplating: protection for metals
These treatments can therefore be defined as processes with both an aesthetic and a technical purpose, designed to protect metals. They improve the quality of the part both visually and in terms of performance. Electroplating has three stages: preparation of the surfaces to be treated, deposition of the metal coating and the finishing treatment that completes the process.
Once finished, the parts are quickly dried in hot-air ovens so that no water marks form.
