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 microstructure of ZChPbSb16-16-2 bearing alloy was investigated under different melt conditions and cooling conditions and how the state transition from liquid to liquid state occurred at different temperatures affected the wear resistance of the material. The results show that the Babbitt alloy undergoes an irreversible liquid-liquid change at a high temperature of 890 ℃. Under the condition of rapid cooling, the internal grains are finer and more evenly distributed, improving the wear resistance of the material . Indicating that changing the melting temperature and cooling rate of the material to improve the wear resistance of the material is feasible.
