Abstract: There are many factors that affect the phosphorus content in the electroless Ni-P coatings The effects of the compositions of plating solution,the PH values of plat ing solution and the deposition temperature on the phosphorus content in Ni-P coatings were investigated in this paper It is found that the phosphorus content in Ni-P coatings increases and the deposition rate decreases with decreasing PH values,nickel sulphate NiSO4 content of plating solution and the deposition temperature.

Key words: electroless Ni-P coatings, phosphorus, deposition rate
