The plating bath solution consisted of nickel sulfate, nickel chloride, phosphorous acid, phosphoric acid and a wetting agent (sodium lauryl sulfate).
Ni-P alloy deposits were prepared at different plating conditions and the effect of various plating parameters like current density, concentration of phosphorous acid, concentration of phosphoric acid and plating temperature on the P content of the coating as well as the rate of deposition was investigated systematically.
By controlling the current density, phosphorous acid concentration, and temperature, bright and adherent Ni-P coatings containing various concentrations of phosphorous were obtained.
