采用爆轰法合成了纳米金刚石。它是一种兼具金刚石和纳米颗粒特性的材料。在化学镀液中加入金刚石纳米颗粒制备了Ni-P-ND复合镀层。研究了该复合镀层在中碳钢表面的摩擦学性能、硬度和腐蚀行为。与Ni-P复合镀层相比，Ni-P-ND复合镀层不仅具有较高的耐磨性，而且具有较低的摩擦系数。Ni-P-ND复合镀层在673 K热处理时的显微硬度最高。Ni-P-ND复合镀层的耐蚀性比Ni-P镀层有上级的提高。讨论了化学复合镀层改善摩擦学和电化学性能的机理。
Nanometer Diamond (ND) was synthesized by using the detonation method. It was a kind of materials with properties of diamond and nanometer particle. The Ni–P–ND composite coating was prepared from a suspension of diamond nanoparticles in electroless bath. The tribological properties, hardness and corrosion behaviours of the composite coating on medium carbon steels were investigated. The Ni–P–ND composite coating exhibits not only high wear resistance but also low friction coefficient compared with the Ni–P composite coating. The highest microhardness of the Ni–P–ND composite coating was obtained by heat treated at 673 K. The corrosion resistance of Ni–P–ND composite coating is superior to that of Ni–P coating. The mechanisms of improvement of the tribological and electrochemical properties of the electroless composite coating are also discussed.
