摘要
采用化学镀及化学复合镀方法,得到了N i-P、N i-M o-P、(N i-M o-P)-A l2O3及(N i-M o-P)-PPS四种镀层;对各种镀层的形貌进行分析,并研究了随热处理温度升高各种镀层耐蚀性能的变化机理。结果表明:N i-M o-P基镀层的耐蚀性优于N i-P镀层;在85℃的10%H2SO4溶液中(N i-M o-P)-PPS镀层的腐蚀速率约是N i-M o-P镀层的1/3。
Ni P, Ni-Mo-P, （Ni-Mo-P）-Al2O3 and （Ni-Mo-P）-PPS coatings were prepared with electroless plating and eleetroless composite plating. Morphology of the coatings was analyzed. Change in corrosion resistance of the coatings with heat treatment temperature was investigated. Experimental results show that corrosion resistance of Ni-Mo-P coating is superior to that of Ni- P coating, and the corrosion rate of （Ni-Mo-P）-PPS coating in 10% H2SO4 solution at 85℃ is just one-third of that of Ni-Mo-P coating.
