Abstract h-BN matrix solid-lubricating composites containing SiC were fabricated by the spark plasma sintering technique. The prepared h-BN/SiC composites exhibited excellent lubricating performance in the wide temperature range from room temperature to 900 °C. With the content of the h-BN increasing from 50 to 75 vol%, the friction coefficients at room temperature decreased from 0.53 to 0.25. Up to 900 °C, the friction coefficients of the h-BN/SiC composites were 0.26–0.34. More content of h-BN was beneficial to reduce the friction coefficient but detrimental to the wear-resistance. The tribological mechanisms were analyzed in details.

h-BN基固体润滑复合材料在高温下的摩擦学性能

摘要 采用放电等离子烧结技术制备了含 SiC 的 h-BN 基固体润滑复合材料。制备的 h-BN/SiC 复合材料在室温至 900 °C 的宽温度范围内表现出优异的润滑性能。随着 h-BN 含量从 50 vol% 增加到 75 vol%,室温下的摩擦系数从 0.53 下降到 0.25。高达 900 °C,h-BN/SiC 复合材料的摩擦系数为 0.26-0.34。h-BN含量增加有利于降低摩擦系数,但不利于耐磨性。详细分析了摩擦学机理。
