摘　　要：在45#钢表面先电镀高硫镍,再化学镀Ni-P合金镀层获得电镀/化学镀双层镍,并制备了单一化学镀Ni-P合金层进行对比。采用中性盐水、酸性盐水和浓盐酸浸泡实验考查了镀层的耐蚀性能,采用热震实验和锉刀实验考查了镀层的结合强度,并分析了镀层的表面形貌和硬度。结果表明:电镀/化学镀双层镍在较薄时就具有与单层Ni-P合金镀镍层相当的耐蚀性能,且与钢基体结合良好。The electroplating/electroless plating＇s two layers nickel on the 45# steel surface was obtained by electroless Ni-P plating after electroplating high sulphur nickel.It was compared with the single electroless Ni-P plating.Two layer nickel＇s corrosion resistance was investigated with the experiments of neutral brine,the acidity brine and thick hydrochloric soaks.Two layer nickel＇s combine strength was studied with the experiments of hot vibration test and file test,and it＇s surface morphology and hardness were analyzed.The experimental results show that the thinner two layers nickel is as the corrosion resistance as electroless Ni-P plating.it is good that the two layers nickel combine with the steel.
