| 摘 要： | 利用化学镀镍的方法，在AZ91D镁合金表面得到了均匀、致密，无明显表面缺陷的Ni－P涂层，X－ray衍射分析表明，镀层组织为单一的Ni；热震实验表明涂层与基体合金结合良好；动电位极化测试表明涂层的自腐蚀电位接近－0．4V（SCE），有明显的钝化区，而腐蚀性能优异，可对基体合金起到理想的防护作用。

| Abstract: | A nickel-phosphor coating was prepared on the surface of AZ91D magnesium alloy by electroless plating.The coating was so uniform and dense that it had no obvious surface defects.The structure of the coating was single phase (Ni) by X-ray diffraction and the adhesion was good by quenching.By dynamic potential polarization,it was shown that the free corrosion potential of the coating approached -0.4 V(SCE) and it had evident passivation.The coating had better corrosion resistance than the substrate,and had extensive application prospect. |
