中文摘要：
利用M200型环-块磨损试验机对TiN薄膜试样、4Cr13强化试样、钨钼钇强化试样、钨钼强化试样、W6Mo5Cr4V2高速钢试样以及T10钢强化试样进行摩擦磨损试验,研究了摩擦系数、磨损量并分析其耐磨机理,结果表明：钨钼钇强化试样、钨钼强化试样、W6Mo5Cr4V2高速钢试样、T10钢强化试样、TiN薄膜试样和4Cr13强化试样的摩擦系数分别为0.3012、0.4693、0.3141、0.5653、0.3171、0.4612;磨损失重分别为：0.0034g、0.0069g、0.0028g、0.0013g、0.0005g、0.0008g。TiN薄膜试样的耐磨性能比4Cr13强化试样提高1.6倍;钨钼钇强化试样耐磨性能比钨钼强化试样、W6Mo5Cr4V2高速钢试样和T10钢强化试样提高2.03倍、0.82倍、3.32倍。钨钼钇强化试样、钨钼强化试样和T10钢强化试样的摩擦系数波动较大,其他试样的摩擦系数较稳定。不同试样的摩擦系数-时间曲线证明磨损分为三个性质不同的阶段：跑合阶段;稳定磨损阶段;剧烈磨损阶段。
英文摘要：
Sliding wear tests on TiN film sample,4Cr13 martensitic stainless steel quenched ＋ tempered sample,W- Mo- Y plasma permeation and strengthening treatment sample,W- Mo plasma permeation and strengthening treatment sample, W6Mo5Cr4V2 quenched sample and T10 quenched ＋ tempered sample were conducted by M200 ring- block wear tester. Wear coefficient,wear loss and wear resistance mechanism were analyzed. The results show that wear coefficient of TiN sample,stainless steel sample,W- Mo- Y sample,W- Mo sample,W6Mo5Cr4V2 sample and T10 sample are 0. 3171,0. 4612, 0. 3012,0. 4693,0. 3141,0. 5653,respectively; The wear coefficients of W-Mo-Y sample,W- Mo sample and T10 sample are fluctuant relatively,and the others are stable relatively; The wear resistance of TiN sample is 1. 6 times of that of stainless steel sample; Relative wear resistance of W- Mo- Y sample is relatively 2. 03,0. 82,3. 32 times of that of W- Mo sample, W6Mo5Cr4V2 sample and T10 sample.
