| 摘 要： | 比较了SiC 和Gr 颗粒混杂增强Al 基复合材料的干摩擦磨损行为, 并与单一SiCP 和单一GrP 增强Al 基复合材料的相应行为进行了比较。结果表明, 在低载荷(< 30 N ) 时, SiCP 和GrP 能协调作用, 使混杂复合材料的摩擦系数和磨损率均比单一SiCP 和GrP 增强复合材料低。在较高载荷(30～ 120 N ) 时, 混杂复合材料磨损以剥层磨损机制为主, 摩擦系数比单一SiCP 增强复合材料低, 磨损率比单一GrP 增强复合材料低得多, 比单一SiCP 增强复合材料高。混杂复合材料对偶件的磨损比单一SiCP 增强复合材料低得多。

| Abstract: | Dry friction and wear behavior of Al matrix composites including those hybridizedly reinforced with 20 vol%SiC and 9 vol%Gr particles, and those separately reinforced with 20 vol%SiC and 9 vol%Gr particles were investigated. The wear tests were performed using a pin on disk wear machine under dry sliding condition, at a speed of 0.6 m/s within a load of 10 N to 120 N. At low loads (<30 N), the friction coefficient and wear rate of hybrid composites were all lower than those of composites reinforced respectively with SiC P and Gr P, because of cooperation of load bearing of SiC P and self lubrication of Gr P. At higher loads (30~120 N), the wear rate of hybrid composite was higher than that of SiC P/Al because of surface delamination of hybrid composite, but was greatly lower than Gr P/Al. The friction coefficient of hybrid coompisite was less than that of SiC P/Al. The wear rate of counterface which mated with pin of hybrid composite was largely lower than that of SiC P/Al at all loads. |
