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:调整铁基粉末合金刹车材料中的石墨含量,制成摩擦试样进行摩擦性能试验,结果表明材料中石墨含量增加,其强度会随之下降,摩擦系数也随之下降,而动摩擦系数则随之上升。
