为了进一步研究化学镀镍磷复合镀层的性能，在研究了镍-磷化学复合镀新配方的基础上，在如钢片表面分别制备了纳米和微米复合材料镀层Ni-P-MgO（CuO）．用称重法测定厚度；通过10％NaCl溶液测定其耐腐蚀性；GB5935-86标准贴滤纸法测镀层的孔隙率；MH-3硬度仪测定其硬度．结果表明：在最佳施镀条件下，可得到耐磨性、硬度强于A3钢片、Ni-P镀层和Ni-P-MgO（CuO）纳米复合镀层的微米复合化学镀层。和光亮致密耐腐蚀性强于A3钢片、和Ni-P-MgO（CuO）微米复合镀层。与Ni-P镀层相当的Ni-P-MgO（CuO）纳米复合镀层．

英文摘要：

In order to further study the properties of electroless nickel-phosphorus composite coating, the Ni-P-MgO （CuO） electroless namometer （micron） composite coatings on the surface of As steel were prepared by the technology of electroless composite plating under the new formula conditions. The thickness, corrosion resistance, porosity, hardness of the coatings were determined by the weighting, the 10% NaCl solution, the GB5935-86 standards and the MH-3 hardness meter, respectively. The result indicated that, under the optimum technical conditions, the wear resistance and hardness of the electroless micron composite coatings were stronger than that of the A3 steel and Ni-P coating. But, the polish, homogeneity and corrosion resistance of the electroless namometer composite coatings were stronger than that of the As steel and electroless micron composite coatings, and were similar to Ni-P coating.
