  • Typical parameters of the process


Process Temperature [°C] Heat transfer medium Residence time Chemicals Concentration Details Literature
Nickel plating 50-60 Nickel sulphate, nickel chloride and boric acid Nickel sulphate: 240-357 g/l; nickel chloride: 35-60 g/l; boric acide: 30-45 g/l Watts-type nickel solution BAT for the surface treatment of metals and plastics, August 2006
Plating with nickel sulphate-based solutions 50-60 Nickel sulphamates (rather than sulphates), boric acid and frequently nickel chloride Nickel sulphamate: 350-600 g/l of the tetrahydrate salt; boric acid: 35-45 g/l; nickel chloride: 1-15 g/l
Plating with nickel chloride- based solutions 70 Nickel sulphamate (rather than sulphate), borica acid and frequently nickel chloride for high concentrations: sulphamate solutions
20-30 Nickel chloride hexahydrate, hydrochloric acid Nickel chloride hexahydrate: 240 g/l; hydrochloric acid: 125 ml/g Woods nickel strike solutions
