Molybdenum squares and molybdenum discs can be plated with nickel, silver and gold on the surface according to different needs. The advantages of different coatings are as follows:
First, nickel plating on the surface:
- Improve welding reliability, high temperature resistance, anti-oxidation (electroplating nickel layer has high stability in air, due to the strong passivation ability of metal nickel, a very thin passivation film can be quickly formed on the surface, which can resist Corrosion by atmosphere, alkali and some acids);
- Both gold and silver plating require a layer of nickel as a transition layer.
Second, gold plating on the surface:
1. Gold plating has low contact resistance, good electrical conductivity, easy welding, strong corrosion resistance, and certain wear resistance (referring to hard gold), so it is widely used in precision instruments, printed circuit boards, integrated circuits, tubes Shells, electrical contacts and other aspects have a wide range of applications.
2. The appearance of the gold-plated layer is golden yellow and has high chemical stability. It is only soluble in aqua regia and other super acids, and insoluble in other acids.
3. The gold plated layer has good ductility, easy polishing, high temperature resistance, and good discoloration resistance.
Third, silver plating on the surface:
After the molybdenum sheet is silver-plated, the surface of the coating is uniform, smooth and silvery white
Molybdenum sheet is plated with silver to reduce the resistance of metal parts and improve the welding ability of metal
Molybdenum sheet is silver-plated to prevent corrosion, increase conductivity, reflectivity and aesthetics. Widely used in electrical appliances, instruments, meters and lighting appliances and other manufacturing industries.
