摘　　要：阐明了孔隙率对Ni-P化学镀层耐蚀性的影响。综述了降低Ni-P化学镀层孔隙率的优化措施,包括多层施镀、钝化封孔、涂覆封孔及热处理等,并探讨了这些措施的防护机制。最后对Ni-P化学镀层的发展方向做了展望。Influence of porosity on the corrosion resistance of electroless Ni-P coatmg was expounded, and measures for decreasing the porosity of electroless Ni-P coating, including multilayer plating, passive sealing, coating sealing and heat treatment, were overviewed. Furthermore, protective mechanisms of these measures were discussed, and the development tendency of electroless Ni-P coating was prospected.
