Electroplating gold plating has strong corrosion resistance, good electrical conductivity, easy welding, high temperature resistance, and certain wear resistance (such as hard gold with a small amount of other elements), good resistance to discoloration, and gold alloy The coating is available in a variety of shades and is gold plated on silver to prevent discoloration. And the coating has good ductility and easy polishing, so it is often used as decorative coating, such as jewellery, watch parts, art, etc.; it is also widely used in precision instruments, printed boards, integrated circuits, electronic tubes, electrical contacts, etc. Parameter performance Long-term stable part plating. However, due to the high price of gold, the application is limited.
The gold plating has strong corrosion resistance, good electrical conductivity, easy soldering, high temperature resistance, and certain wear resistance (such as hard with a small amount of other elements). gold). Therefore, it is widely used in precision instrumentation, printed boards, integrated circuits, electronic tube cases, electrical contacts and other parts requiring long-term stability of electrical parameters. Gold plating is also used as a decorative coating for electroplating jewellery, watch parts, and artwork. Gold plating on silver prevents discoloration. The gold plating solutions currently used include cyanide plating solutions, low cyanide citrate plating solutions, and sulfite plating solutions.
