摘　　要：在转速200 r／min,载荷为750,1 000,1 500 N和转速400 r／min,载荷为300,500,750, 1 000,1 500 N下,对比了新型铝基滑动轴承合金(TZS88)和ZQSn6-6-3的摩擦特性。结果表明: TZS88的减摩性、耐磨性优于ZQSn6-6-3,可用于取代ZQSn6-6-3制造滑动轴承。TZS88磨损试样的扫描电镜观察表明:其中的锡均匀分布于工作面上,具有润滑、降低摩擦因数和抗咬合的作用。Under 200 r/min sliding velocity, 750, 1 000, 1 500 N loads and 400 r/min sliding velocity, 300, 500, 750, 1 000, 1 500 N loads, wear characteristics of a new aluminum matrix bearing alloy （TZS88） and tin bronze ZQSn6-6-3 were studied. The antifriction performance and wear resistance of TZS88 were better than those of tin bronze ZQSn6-6-3, and could be used to substitute for ZQSn6-6-3 in fabricating sliding bearing. SEM micrographs of TZS88 wear specimen showed that Sn-phase was evenly distributed on the working surface, which had functions as lubricating, decreasing coefficient of friction etc.
