摘要: 

在销盘式“HST-100高速载流摩擦磨损试验机”上,对比考查了C/C复合材料与现役电力机车使用的浸金属碳滑板材料的抗电弧侵蚀性能。借助扫描电子显微镜(SEM)和X射线衍射仪(XRD)结合摩擦表面宏观温度的测量,研究了摩擦表面的物相组成与形貌。结果表明,随着速度的增加,两种材料的摩擦系数和磨损率都随之增加,但C/C复合材料的摩擦系数和磨损率均低于浸金属碳材料,且增加的趋势较小。 C/C复合材料具有优异的摩擦学性能和载流质量,满足后续高速滑板材料的发展需要。

Abstract

To understand the arc erosion properties of carbon/carbon (C/C) composites with electric current, the experiments were carried out on the HST-100 tribo-tester with QCr0.5 disk under electric current, and compared with the materials of metal-impregnated carbon, which used in electric railway. Microstructure and phase composition of the friction surface were observed and analyzed by scanning electron microscope(SEM) and X-ray diffractometer(XRD), and macroscopic temperature of the fiction surface were measured. The results show that values of friction coefficients and wear rate of two kinds materials increased with increase of velocities. But both the friction coefficient and wear rate of C/C composites were lower than that of metal-impregnated, and the tendency of increment was poor. The C/C composites own an outstanding tribological characteristic and excellent current-carrying quality, and meets the performance requirements of the contact strip under high speed.
