摘　　要：采用化学镀工艺方法在铝合金剑杆头表面镀一层 Ni- P合金 ,代替进口的剑杆头。对铝合金剑杆头的预处理工艺、镀液的配方、施镀工艺以及镀后热处理工艺进行了研究 ,确定了简便易行的施镀工艺及镀后热处理工艺。所确定的镀液配方 ,性能稳定 ,可获得 4 0 μm以上厚度的镀层 ,且镀层与基体的结合力较好 ,其硬度可达 110 0 HV以上 。A way which uses eletrcless plating of Ni P alloy to treat the Al alloy rapier head,instead of the import one,is introduced.After analysing the effect of pretreatment,plating solution formula,plating technique and post heat treatment,a simple and practicable plating and post heat treat technique is found out.The performance of the determined plating solution formula is stable.A plating coat thickness more than 40 μm can be obtained.The combination of the plating coat with base is good.The hardness of the coat is above 1100Hv.Its multiple performance is equal to the import one's.
