研究了不同蠕化率条件下蠕墨铸铁在不同载荷下的耐磨性能。结果表明,随着蠕化率的增大,蠕墨铸铁的抗磨损性能降低。蠕化率为50%~60%时,随着载荷的增加,蠕墨铸铁磨损机制由磨粒磨损转变为磨粒磨损和黏着磨损的混合形式。蠕化率为80%~90%时,随着载荷的增加,蠕墨铸铁的磨损机制最终几乎全部转变为表面疲劳磨损。 The wear resistance of vermicular graphite cast iron under different loadings was studied under different conditions of creep rate. The results show that as the creep rate increases, the anti-wear performance of vermicular cast iron decreases. With the increase of load, the wear mechanism of vermicular cast iron changed from abrasive wear to a mixture of abrasive wear and adhesive wear with a rate of 50% ~ 60%. When the creep rate is 80% -90%, the wear mechanism of vermicular graphite cast iron eventually changes to almost all surface fatigue wear with the increase of load.
