Abstract

In order to improve the deposition rate,hardness and anti-corrosion properties of electroless Ni-Mo-P plating,the effects of composition,pH value,complex,surface active agents and stabilizing agents on the deposition rate,hardness and corrosion resistance of electroless Co-Ni-P plating,were studied,The optimum formula and process were acquired as follows: Na2MoO4(2.4 g/L),NiSO4·6H2O(26.2 g/L),NaH2PO2·H2O(10.6 g/L),Na3C3H5O7·2H2O(30 g/L),KI(1 mg/L),CH3(OH)CHCOOH(9 g/L),sodium dodecylbenzene sulfonate acid(50 mg/L),pH8.5,temperatures(90 ℃),It is very important to choose the proper process for obtaining a desired quality of electroless plating Ni-Mo-P.
