通过正交实验，以沉积速率和腐蚀速率为指标，获得了优化化学镀Ni-W-P镀液配方。采用扫描电镜、X 射线衍射、能谱分析了镀层的微观形貌、组成及结构，研究了镀层在10%H2SO4+30%HCl的耐蚀性能。结果表明，化学镀Ni-W-P合金镀层的耐蚀性能与镀层的非晶态结构、P和W的含量以及腐蚀介质的性质等因素有关，W对镀层获得非晶结构的作用要大于P的作用。

Optimized process of electroless deposition of Ni-W-P alloy were determined by orthogonal experiment.Deposition rate and corrosion resistance were taken as the index for assessment.The anti-corrosion behavior of the Ni-W-P alloy coating was studied in the environment 10%H2SO4+30%HCl,and the results show that the corrosion resistance of Ni-W-P mainly depends on its amorphous structure, the content of P,W and the nature of the corrosive medium,the role of the W than the P in the aspect of amorphous structure.
