摘 要: 研究了短碳纖維增強(qiáng)錫基巴氏合金的摩擦學(xué)特性。 結(jié)果表明： 與鑄態(tài)錫基巴氏合金相比， 6%(體積分?jǐn)?shù))的短碳纖維的加入， 降低并穩(wěn)定了錫基巴氏合金與鋼配副的摩擦系數(shù)， 使其更易跑合， 特別是顯著地延長(zhǎng)了合金的穩(wěn)定磨損期，使合金不易發(fā)生劇烈的粘著磨損， 從而使錫基巴氏合金的摩擦學(xué)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
