Plating (Electroplating) process is to use the principle of electrolysis plating on a thin layer of metal or alloy in some metal surface, is the process of making the surface of metal or other material parts attached to a layer of metal film by electrolysis so as to prevent corrosion, improve wear resistance, electrical conductivity, reflective and improves the appearance effect.

The purpose of electroplating: electroplating in addition to the requirements of beauty, in accordance with a variety of electroplating needs and different purposes.

1., copper plating: bottoming, to enhance the adhesion ability of plating layer, and corrosion resistance.

2. nickel plating: bottoming or appearance, to improve corrosion resistance and abrasion resistance (in which chemical nickel for the modern process, the ability to wear more than chromium plating).

3. gold-plated: improve the conductive contact resistance, improve signal transmission.

4., palladium plating nickel: improve the conductive contact resistance, improve signal transmission, wear resistance is better than gold.

5. Tin Lead: increasing welding ability, quickly replaced by other substitute (because most lead is changed to bright tin and fog tin).
