硫酸镍对Ni-W-P化学镀层性能的影响

Effect of Nickel Sulfate on the Performances of Electroless Ni-W-P Coating

在不锈钢表面制备了Ni—W—P化学镀层。研究了硫酸镍的质量浓度对Ni—W—P化学镀层的沉积速率及电化学性能的影响，并用SEM表征了Ni—W—P化学镀层的表面形貌。最终确定硫酸镍的最佳质量浓度范围为25-35g／L。Ni—W—P化学镀层均匀地覆盖不锈钢基体，起到了很好的保护作用。

Ni-W-P coatings Effects of nickel sulfate were prepared on the surface of stainless steel by electroless plating. mass concentration on the deposition rate and electrochemical performances of electroless Ni-W-P coatings were investigated, and the surface morphology of electroless Ni-W-P coatings was characterized by SEM. The optimum mass concentration range of nickel sulfate was 25 - 35 g/L. Electroless Ni-W-P coatings well-proportioned covered on stainless steel, playing a good role in protecting the suhstrate.
