研究了水润滑条件下Cu/C/RBC复合材料的摩擦磨损性能。铜、碳和RB陶瓷颗粒的质量分数分别为60、35和5质量%。RB陶瓷颗粒的平均直径为4.9 μm。在水润滑条件下，用销盘摩擦装置进行摩擦试验。Cu/C/RBC复合材料和铜/碳（Cu/C）复合材料被用作圆盘试样。Cu/C复合材料是日本传统的受电弓滑板材料。使用铜合金作为针试样，其用于模拟接触线。Cu/C/RBC复合材料的摩擦系数比Cu/C复合材料的摩擦系数低且更稳定。结果表明，Cu/C/RBC复合材料具有良好的上级摩擦磨损性能，与Cu/C复合材料相比，摩擦系数降低70.0%，比磨损率降低86.1%，比磨损率降低99.1%。
In this paper, friction and wear properties of a copper/carbon/rice bran ceramics (Cu/C/RBC) composite under water-lubricated conditions were investigated experimentally. The mass fractions of copper, carbon and the RB ceramics particulates were 60, 35 and 5 mass%, respectively. The mean diameter of the RB ceramics particulate was 4.9 μm. Friction tests were conducted with a pin-on-disk friction apparatus under water-lubricated conditions. The Cu/C/RBC composite and a copper/carbon (Cu/C) composite were used as disk specimens. The Cu/C composite is a conventional pantograph slider material in Japan. A copper alloy was used as a pin specimen, which was used to simulate a contact wire. The friction coefficients for the Cu/C/RBC composite were lower and more stable than those for the Cu/C composite. The Cu/C/RBC composite showed superior friction and wear properties such as 70.0% reduction in friction coefficient, 86.1% reduction in the specific wear rate of the composite disk and 99.1% reduction in that of the copper-alloy pin compared with the Cu/C composite.
