摘　　要：为提高Ni-W-P化学镀层与高速钢基体之间的结合力,重点研究了高速钢化学镀前的表面活化处理工艺。以不同浓度的盐酸、硫酸、氢氟酸和活化时间为研究对象,以Ni-W-P镀层与高速钢基体的结合力为研究指标,通过正交试验对活化剂组分和活化时间进行优化。结果表明,在试验条件下,当活化剂中添加8%的浓盐酸和2.5%的氢氟酸(其余为水)并对高速钢基体进行3 min活化处理时,制备的Ni-W-P镀层与基体的结合力最大。In order to improve the the adhesion between the Ni-W-P electroless plating layer and the high-speed steel substrate,the surface activation process before electroless plating of the high-speed steel is studied.Taking hydrochloric acid,sulfuric acid,hydrofluoric acid and activation time of different concentrations as the research object,and the adhesion between Ni-W-P coating and high-speed steel matrix as the research index,the activator components and activation time are optimized by orthogonal test.The results show that under the test conditions,when the activator is added with 8%concentrated hydrochloric acid and 2.5%hydrofluoric acid and the high-speed steel substrate is activated for 3 minutes,the adhesion between the prepared Ni-W-P coating and the substrate is the largest.
