摘　　要：为了提高汽车行星齿轮轴的耐磨性和耐腐蚀性,设计了CVD沉积纳米Ti N合金镀层工艺,并在轴表面制备了纳米Ti N合金镀层;通过试验分别研究了镀层硬度与纳米Ti N含量间的关系,以及镀层的耐磨性耐腐蚀性能。结果表明:镀层硬度随Ti N质量的增加而增大,耐磨性和耐腐蚀性均有成倍提高。In order to improve the wear resistance and corrosive resistance of the automobile planet gear axle,the deposition technique of CVD was used to prepare the plating of nano Ti N alloy in the axle surface.The influences of nano Ti N on hardness,wear resistance and corrosive resistance of plating were researched.The results show that when nano Ti N is added into the alloy layer,the hardness increases,mean while,the wear resistance and corrosive resistance increase manyfold.
