研究了RB陶瓷颗粒的粒径和质量分数对RB陶瓷颗粒填充聚酰胺66复合材料（PA 66/RB陶瓷复合材料）与轴承钢球在干摩擦条件下的摩擦磨损性能的影响。使用平均直径为3、30和150 μm的RB陶瓷颗粒作为填料。RB陶瓷颗粒的重量分数对于平均直径为3 μm的颗粒为10、30和50质量%，对于平均直径为30和150 μm的颗粒为30、50和70质量%。RB陶瓷颗粒的平均粒径越小、质量分数越高，则PA 66/RB陶瓷复合材料的摩擦系数和比磨损率越低。当RB陶瓷颗粒平均粒径为30 μm、质量分数为70%时，复合材料的摩擦系数最低，为0.27。当RB陶瓷颗粒平均粒径为3 μm、质量分数为50%时，复合材料的比磨损率最低，为1.3 × 10- 9mm 2/N，与RB陶瓷圆盘的比磨损率相当。
This study investigated the effect of a particle diameter and a weight fraction of RB ceramics particles on friction and wear of polyamide 66 composites filled with RB ceramics particles (PA66/RB ceramics composites) sliding against a bearing steel ball under dry condition. RB ceramics particles with a mean diameter of 3, 30, and 150 μm were used as the filler. Weight fractions of RB ceramics particles were 10, 30, and 50 mass% for the mean diameter of the particles of 3 μm, and 30, 50, and 70 mass% for the mean diameters of 30 and 150 μm. The smaller mean diameter and the higher weight fraction of RB ceramics particles provided lower friction coefficients and lower specific wear rates with the PA66/RB ceramics composites. The composite with a mean diameter and a weight fraction of RB ceramics particles of 30 μm and 70 mass% took the lowest friction coefficient of 0.27 among the composites. The composite with a mean diameter and a weight fraction of RB ceramics particles of 3 μm and 50 mass% took the lowest specific wear rate of 1.3 × 10-9mm2/N among the composites, which was equivalent to the specific wear rate of RB ceramics disk.
