The chemistry of nickel electroplating solutions

May 09, 2017· The three nickel salts examined sulphate, chloride and sulphamate are the ones most commonly used in these processes. Despite the fact that nickel plating was first invented in 1837 and has become an extremely useful part of high technology applications the nature of the species in solution has never been investigated.

Nickel electroplating Wikipedia

Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. To clean and protect the part during the plating process, a combination of heat treating, cleaning, masking, pickling, and etching may be used. Once the piece has been prepared it is immersed into an electrolyte solution and is used as the cathode. The nickel anode is dissolved into the electrolyte to form nickel ions. The ions travel through the solution
