摘　　要：使用微米氧化铝（Al2O3）为增强剂,以尼龙1010为基体,进行氧化铝/尼龙复合材料在煤泥润滑条件下的滚滑动摩擦磨损实验.通过实验发现,水能降低氧化铝/尼龙复合材料的摩擦系数,但增大了磨损量.煤泥润滑时尼龙1010材料的摩擦系数为0.096;氧化铝/尼龙复合材料的平均摩擦系数为0.089,只有纯尼龙的92.7%.尼龙磨损量是3.32mm^3;Al2O3/尼龙复合材料的磨损量平均为15.73mm^3;Al2O3/尼龙复合材料的平均磨损量平均是尼龙的4.74倍.This paper mainly studies on the rolling- sliding friction and wear properties of Micron- Al2O3/nylon1010 composites under slime condition. The mechanism of the wear of Al2O3/nylon1010 composites is researched. The tests show slime can decrease the friction coefficient and increase wear volume of composites. First the friction coefficient of nylon 1010 is 0. 096, but that of Al2O3/nylon composites is about 45% of nylon1010; Second wear volume of nylon is 3.32mm^3, and that of Al2O3nylon 1010 composites is 4. 74 times of it.
