摘　　要：采用化学镀的方法实现了纳米C60晶体的表面金属化,然后通过激光诱导的方法,在微细构件表面,化学复合镀覆了Ni-P/纳米C60的复合镀层。采用扫描电子显微镜和PLINT高温微动疲劳试验机对镀层的组织形貌和摩擦学性能进行了表征分析,并考察了工艺参数对其的影响,结果表明基于C60的特殊分子结构以及其在摩擦磨损过程中所起的作用,镀层的摩擦系数明显减小,耐磨性能显著提高。The surface metallization of nano-C60 crystals are achieved by electroless nickel plating; Then, a new composite coating is got on a micromechanical device by the laser-induced way, which contained some metalized nano-C60 crystals. The microstructure and wear resistance of the coating are characterizedby scanning electronmicroscopy （SEM＇） and PLINT test machine. The effects of process parameters on microstructure and wear resistance of the coating were investigated. Due to the nano-C60 extraordinary rigidity and special molecule structure, the composite coating has a lower friction coefficient and an excellent wear resistance performance.
