纳米金刚石的嵌入不改变复合镀层的结构，但使镀层表面形成不平整的、微小球粒堆砌状形貌。
The embedded nanometer diamond particles don′t change the structure of Ni-P matrix, but coarsen the surface of the composite coating with a large number of spherical particles.
研究了化学复合镀纳米金刚石粉的不同施镀工艺，并分析了复合镀层的性能和结构。
The process of Ni-P nanometer diamond composite electroless plating was studied. The structure and hardness of the composite coating were analysed.
结果表明，纳米金刚石微粉的加入可改善复合镀层的结合强度，显著提高镀层硬度和耐磨及减摩性能。
The result indicates, adding nano-diamond powder can improve the joint intensity of composite coating, remarkably enhance hardness, wear-resisting and antifrictional performance of the…
