| 摘 要： | 以铝基复合材料作为列车制动盘材料的实用化为目的,选用A356/SiC 20%(体积分数,下同)复合材料和AISI D2工具钢为摩擦材料,以中速列车实用中的有机闸片为对偶材料,进行对比干摩擦磨损试验,并分析比较了磨损特性.结果表明:铝基复合材料在小于200 N(3.98 MPa)的低载荷下,只存在轻微的氧化磨损,耐磨性比实用中的铁合金材料更好;而超过该载荷时,开始发生磨削磨损,磨损量逐步超过铁合金材料,当载荷达到400 N(7.96 MPa)时,由于严重的磨削磨损,磨损量剧增.而铁合金材料则随载荷和滑动速度增加,磨损率缓慢增加;磨损过程中的复合材料的摩擦系数平均值与载荷、滑动速度无关,始终保持0.3～0.4,同时随磨损距离的波动也非常小,而工具钢的摩擦系数平均值则对试验参数的敏感度相对大些,且摩擦系数平均值也比复合材料略小,即摩擦系数方面复合材料具有更好的特性.
