摘要
在M2000型、MG1000型高温摩擦实验机上，将3种C／C复合材料分别与40Cr镀Cr钢、W18Cr4V钢配副进行滑动摩擦实验。结果表明：在环—块滑动摩擦实验中，随时间延长，试样摩擦系数均趋向平稳，质量磨损量均增长。其中，低密度试样的摩擦系数较高，在0．13～0．18之间波动；在销—盘滑动摩擦实验中，室温下，20N时，具有粗糙层／光滑层／树脂炭试样摩擦系数为0．13、1h质量磨损为1．1mg，40N时分别为0．10和0．9mg，60N时分别0．15和3．9mg为；200℃时，试样的摩擦系数和1h质量磨损均大幅度增加，分别在0．16～0．27和4．1～5．8mg之间；“跑合”期间，随时间延长，试样的摩擦系数和磨损量均逐渐增大；“跑合”结束后，摩擦系数变小，磨损量趋于稳定；随转速增加，试样的摩擦系数和质量磨损均增加。
Using M2000 wear tester and MG1000 high temperature wear tester, the sliding tribology behavior of three kinds of C/C composites with different matrix carbon were investigated with 40Cr steel coated by Cr or W18Cr4V steel as couple. The result shows that in the ring-block sliding wear test, with time prolonging, the friction coefficient of all samples becomes more and more stable, and the mass wear loss increases. Among such samples, the samples with low density hold high friction coefficient between 0. 13 - 0.18. In the pin-dish sliding wear test, at room temperature, under 20 N test, the friction coefficient of the sample with rough lamination/smooth lamination/resin carbon is 0.13 and the mass wear loss after 1 h test is 1.1 rag, and those under 40 N test are 0.10 and 0. 9 rag, respectively, and those under 60 N are 0.15 and 3.9 mg, respectively. At 200 ℃, the friction coefficient and mass wear loss increase quickly which varly among 0.16 - 0. 27 and 4.1 - 5.8 mg, respectively. During the time of running in, the friction coefficient and mass wear loss increases with time prolonging. After the running in, the friction coefficient decreases and the mass wear loss gets stable. With revolving speed increases, both the friction coefficient and mass wear loss increase.
