摘　　要：研究在不同熔融状态和冷却条件下,ZChPbSb16-16-2轴承合金内部微观结构的差异,以及不同温度下合金发生的液态到液态之间的状态转变如何影响材料的耐磨性能。结果表明:在890℃的高温下,巴氏合金发生了不可逆转的液-液状态下的变化,在快速冷却的条件下,内部晶粒更细小、分布更均匀,提高了材料的耐磨性能。说明改变材料的熔融温度和冷却速率对提高材料的耐磨性是可行的。The internal microstructure differences of ZChPbSb16-16-2 beating alloy under different melting states and cooling conditions were studied, and the influence of liquid-liquid structure change of the alloy under different temperature on wear resistance was investigated. The results show that, at the high temperature of 890 ℃, the irreversible liquid-liquid state change happens in Babbitt alloy. Under rapid cooling conditions, the microstructure is finer and more uniform, which improve the wear resistance of materials. It is showed that the change of melting temperature and cooling rate can improve the wear resistance of the material.
