采用针盘式摩擦磨损试验机，研究了含不同hBN量的B4C-hBN陶瓷复合材料自配偶的干滑动摩擦学性能，并利用扫描电镜对B4C-hBN试样的磨损表面进行了观察和分析。研究发现，B4C-hBN陶瓷复合材料自配偶的干滑动摩擦学性能具有明显的规律性：随着hBN含量的增加，摩擦系数逐渐减小，磨损系数逐渐增大。摩擦系数降低的主要原因是在B4C-hBN试样磨损表面形成了转移膜。研究了薄膜的形成过程。
In this paper, dry sliding tribological properties of self-mated couples of B4C-hBN ceramic composites containing different amounts of hBN have been evaluated using a pin-on-disc friction and wear machine, and the worn surfaces of B4C-hBN specimens have been observed and analyzed by scanning electron microscope (SEM). It is found that the dry sliding tribological properties of self-mated couples of B4C-hBN ceramic composites take on obvious regularity: with hBN content increasing, the friction coefficient gradually decreases, but the wear coefficient gradually increases. The decrease of friction coefficient could be largely attributed to the formation of a transfer film formed on the wearing surface of the B4C-hBN specimens. The formation of the film is investigated.
