abstract : with the graphite content adjusted, a friction performanceexperiment is carried on the iron-base powder alloy brake material sample . the results show that the graphite increases with the decrease of the strength and the static friction coefficient of the material, while the dynamic friction coefficient increases correspondingly 文摘:調(diào)整鐵基粉末合金剎車材料中的石墨含量,制成摩擦試樣進(jìn)行摩擦性能試驗,結(jié)果表明材料中石墨含量增加,其強(qiáng)度會隨之下降,摩擦系數(shù)也隨之下降,而動摩擦系數(shù)則隨之上升。
