本研究开发了五种热塑性树脂/RB陶瓷复合材料，并研究了它们在干润滑和油润滑条件下的摩擦学性能。平均直径为 150 µm 的 RB 陶瓷颗粒与五种热塑性树脂（PA66、PA11、PBT、POM 和 PP）复合。这些化合物通过注射成型形成圆盘几何形状。 RB陶瓷颗粒的重量分数对于POM为50重量％，对于PA11和PBT为60重量％，对于PA66和PP为70重量％。热塑性树脂/RB陶瓷复合材料在干燥条件下的摩擦系数低于纯热塑性树脂，并且在油润滑条件下低滑动速度下的摩擦系数也低得多。与纯热塑性树脂相比，在干润滑和油润滑条件下，热塑性树脂/RB陶瓷复合材料也获得了针对滑动速度变化的稳定的摩擦系数值。此外，与纯树脂相比，新开发的复合材料在干燥条件下（减少 67-98%）和油润滑条件下（减少 68-99%）比磨损率显着降低。这些结果表明 RB 陶瓷颗粒可以用作聚合物复合材料的填料，提供低摩擦和高耐磨性。
In this study, five kinds of thermoplastic resin/RB ceramics composite materials were developed, and their tribological properties were investigated under dry and oil lubricated conditions. RB ceramics particles with mean diameter of 150 µm were compounded with five kinds of thermoplastic resins (PA66, PA11, PBT, POM, and PP). These compounds were formed into disk geometry by injection molding. A weight fraction of RB ceramics particles were 50 wt% for POM, 60 wt% for PA11 and PBT, and 70 wt% for PA66 and PP. Friction coefficients of the thermoplastic resin/RB ceramics composites were lower than those of the neat thermoplastic resins under dry condition, and those were much lower at low sliding velocities under oil lubricated condition. A stable value of friction coefficient against sliding velocity variation was also obtained for the thermoplastic resin/RB ceramics composites as compared with the neat thermoplastic resins under both dry and oil lubricated conditions. Furthermore, a remarkable reduction of specific wear rate was achieved for the newly developed composites as compared with the neat resins under dry condition (67-98% reduction) and oil lubricated conditions (68-99% reduction). These results would suggest that RB ceramics particles can be applied as filler for polymer composites providing both low friction and high wear resistance.
