The tribological tests under water lubrication have been made on B4C-SiC composite ceramics in contact with different counterparts (Si3N4, Al2O3, and SUJ2 (high carbon chromium steel)). When the B4C-SiC discs slide against different counterparts in water, similar coefficients of friction are obtained, except against SUJ2 counterpart at 40 N. The B4C-SiC discs show the highest wear rate when sliding against Si3N4 counterpart, followed by Al2O3 counterpart, and lastly SUJ2 counterpart. The wear of B4C-SiC disc when sliding in water mainly depends on the nature of counterparts, followed by the hardness of counterparts. As a whole, B4C-SiC/Al2O3 tribo-couple shows better tribological properties when sliding in water as compared to B4C-SiC/Si3N4 tribo-couple and B4C-SiC/SUJ2 tribo-couple.

B4C-SiC复合陶瓷在水润滑下的摩擦学行为:对应物的影响
对与不同对应物(Si 3 N 4、Al 2 O 3和SUJ2(高碳铬钢))接触的B 4 C-SiC 复合陶瓷进行了水润滑下的摩擦学试验。当 B 4 C-SiC 圆盘在水中与不同的对应物滑动时,获得相似的摩擦系数,除了在 40 N 时与 SUJ2 对应物相比。 B 4 C-SiC 圆盘在与 Si 3 N 4对应物滑动时显示出最高的磨损率,其次是 Al 2 O 3对应物,最后是 SUJ2 对应物。B 4的磨损C-SiC盘在水中滑动时主要取决于对应物的性质,其次是对应物的硬度。总体而言,与 B 4 C-SiC/Si 3 N 4摩擦偶和 B 4 C-SiC/SUJ2 摩擦偶相比,B 4 C-SiC/Al 2 O 3摩擦偶在水中滑动时表现出更好的摩擦学性能-夫妻。
