Sulfamate Nickel And Chloride
Is it necessary to have chloride in our sulfamate nickel plating bath?
Q: Is it necessary to have chloride in our sulfamate nickel plating bath? M. M.
A: The direct answer is no. Chloride ion is added to sulfamate nickel plating baths to help with the dissolution of the anodes (anode efficiency), but it is not essential. If your sulfamate plating bath does contain chloride, be aware that the tensile strength of the nickel deposit will increase in proportion with chloride concentration. This can increase the stress in the deposit, which can be a cause of the deposit cracking.
