摘　　要：本研究通过采用高能机械化学法对其进行分散。研究表明,与超声波、机械搅拌和化学方法相比,高能机械化学法处理后镀液中纳米颗粒更多的处在纳米数量级,并可长时间悬浮（20h以上）,长时间（30天）静置后镀液中颗粒仍有大部分处在纳米级。所制备的复合镀层中纳米颗粒含量较高;镀层的表面均匀、致密、平整;镀层的显微硬度也提高了15%～30%。　A new composite method,named high-energy-mechanical and chemical method（HEMCM）,was used to deconcentrate the ceramic nanoparticles within metal matrix solution.Comparing with the other methods,such as supersonic method,mechanical method or chemical method,much more nanoparticles were in nanometer scale in the composite solution after prepared by HEMCM.And the nanoparticles can suspend steadily as longer as twenty hours.Furthermore,most of the particles in composite solution were in nanometer scale after one month.What＇s more,the proportion of nanoparticles is much higher in the coating prepared by this method.The surface of the coating is even,compact and smooth.The micro-hardness increases by 15%-30%.
