Sulfamate Nickel Plating Services Sulfamate Nickel Deposit Properties Sulfamate nickel plating is an electrolytic plating process first developed by Piontellil and Cambri in 1938. The primary difference in the sulfamate nickel plating bath is the use of nickel sulfamate rather than the nickel sulfate as is used in the traditional Watts nickel plating solution developed by Oliver Watts in 1916.
