摘要(Abstract)：

研究了等温淬火工艺对等温淬火球墨铸铁(ADI)组织、力学性能及磨损性能的影响。结果表明,在等温淬火温度290～380℃范围内,随着等温淬火温度的升高,ADI基体组织逐渐变粗,残留奥氏体量增多,硬度逐渐下降,ADI试样的磨损率增加,摩擦系数减小。研究可知,ADI磨损机制主要有微观切削磨损、氧化剥落磨损、犁沟和表面疲劳磨损。当等温淬火温度为较低时,290和320℃时ADI磨损机制主要为微观切削磨损和氧化剥落磨损;等温淬火温度为350℃时,ADI磨损机制主要为微观剥削磨损和犁沟,以及少量的氧化剥落磨损;等温淬火温度升高至380℃时,ADI的磨损机制主要为表面疲劳磨损和犁沟。
