摘要:
针对镁合金表面化学性质活泼，难以通过直接纳米化学复合镀获得高质量镀层的问题，采用双层复合镀的方法（先进行化学镀 N-P 预处理后再进行复合镀）获得了优质的Ni-P-ZrO2 纳米化学复合镀层，研究了镀液中纳米粉的加入量以及不同搅拌方式对镀层中纳米粉复合量的影响，并测量了不同纳米粉复合量镀层的显微硬度和耐蚀性。结果表明：复合镀层的显微硬度随着共沉积的纳米粉量的增多而逐渐增高，但耐蚀性先增加后降低，镀层中纳米粉复合量在 5 wt.% 左右时，镀层的耐蚀性优异，硬度高。
Abstract:
： In view of the active chemical properties on the surface of magnesium alloy and the difficulty of obtaining high-quality coating by direct nano electroless composite plating ， a high-quality Ni-P-ZrO 2 nano electroless composite coating was obtained by double-layer composite plating （ electroless Ni-P pretreatment before composite plating ） . The effects of the amount of nano powder in the plating solution and different stirring methods on the composite amount of nano powder in the coating were studied ， and the microhardness and corrosion resistance of the coating with different composite amount of nano powder were measured. The results show that the microhardness of the composite coating increases gradually with the increase of the amount of codeposited nano powder ， but the corrosion resistance first increases and then decreases. When the amount of nano powder in the coating is about 5 wt.% ， the coating has excellent corrosion resistance and high hardness.
