Advantages of nickel, gold and silver plating on the surface of molybdenum products
Nickel plating on the surface
- Improve the reliability of welding, high temperature resistance, anti-oxidation (the stability of nickel plating layer in air is very high, because the metal nickel has a strong passivation ability, it can quickly form a very thin passivation film on the surface, which can resist the corrosion of atmosphere, alkali and some acids)
- Both gold and silver plating need a layer of nickel as a transition layer。
Gold plating on the surface
- Gold plating has low contact resistance, good conductivity, easy welding, strong corrosion resistance, and certain wear resistance (hard gold), so it is widely used in precision instruments, printed circuit boards, integrated circuits, tube shells, electrical contacts, etc.
- The appearance of gold plating layer is golden yellow, with high chemical stability, only soluble in aqua regia and other super acids, insoluble in other acids.
- The gold plating layer has good ductility, easy polishing, high temperature resistance, and good anti discoloration performance
Ag plating on the surface
- Agcoating is used to prevent corrosion, increase conductivity, reflective and beautiful. Widely used in electrical appliances, instruments, meters and lighting appliances manufacturing industry
