What is black nickel
A kind of black coating sets nickel, zinc, sulfur, organic matter as one, which is commonly known as black nickel. Black nickel layer has a very good extinction effect. The hardness of black nickel is higher than that of galvanized black passivation layer and copper oxide layer, and it has good corrosion resistance, which is commonly used in optical instruments and photographic equipment parts.
The following problems should be paid attention to when plating black nickel:
1.We should pay attention to connect to power supplies first, then enter the slot, and the power can not be cut off in the process of operating.
2.We should always clean up the coating on the rack to ensure the conductive contacting is good.
3.Cast iron parts and some metal parts should be pre plated zinc and then plated black nickel to ensure good binding force.
4.The plating time should reach a certain time, otherwise it will have some trouble.
