摘 要: 研究了短碳纤维增强锡基巴氏合金的摩擦学特性。 结果表明： 与铸态锡基巴氏合金相比， 6%(体积分数)的短碳纤维的加入， 降低并稳定了锡基巴氏合金与钢配副的摩擦系数， 使其更易跑合， 特别是显著地延长了合金的稳定磨损期，使合金不易发生剧烈的粘着磨损， 从而使锡基巴氏合金的摩擦学特性得到改善。

Abstract:The tribological characteristics of short carbon fiber-reinforced Sn-matrix Babbitt alloy were investigated. The results show that short carbon fiber-reinforced Sn-matrix Babbitt alloy could more easily run compared with as-cast Sn-matrix Babbitt alloy and its friction coefficient mating with steel becomes very stable during the whole testing course. Especially, the mild-wear stage of the composite is lengthened and the severe adhesive wear of the composite does not occur easily, thus the tribological characteristics of as-cast Sn-matrix Babbitt alloy are modified.
Key words: Sn-matrix Babbitt alloy carbon fibre tribological characteristics
