滑动速度对团球共晶体增强奥氏钢基自生复合材料摩擦学性能的影响
, PP. 550-554
Keywords: 奥氏体钢,团球共晶体,自生复合材料
Abstract:
利用MPX-2000型主轴盘销式磨损实验机和扫描电子显微镜(SEM)研究了相对滑动速度对团球γ+(Fe,Mn)3C共晶体增强奥氏体钢基自生复合材料(EAMC)摩擦学性能的影响.实验表明,在干摩擦磨损工况下,EAMC对G45钢摩擦系统的摩擦系数随相对滑动速度的增加呈递减趋势;而磨损率呈递增趋势,但始终远低于奥氏体中锰钢(单一奥氏体相);并且,随着相对滑动速度的提高,EAMC与中锰钢磨损量的差值呈递增趋势.通过对磨损表面和磨屑形貌的分析,发现EAMC在低载下主要磨损机制是磨粒磨损与剥层磨损;高载下的磨损机制主要为剥层磨损与氧化磨损.对偶件之间的粘着作用随相对滑动速度的提高而增加.运用临界转变温度理论与Archard磨损理论分析了相对滑动速度对EAMC摩擦学性能影响的机制.
