在干燥氩气气氛中,以亚稳态的304~#奥氏体不锈钢和稳态的310~#不锈钢作为试块,以M_2工具钢作为试环,在LFW-1型环块机上进行滑动磨损实验,用扫描电镜(SEM)、透射电镜(TEM)和扫描透射电镜(STEM)对磨损表面和亚表面进行了观察和分析,结合磨损表面上的显微硬度的测量结果可知,在304~#不锈钢中,形变马氏体的形成对磨屑的生成和成份有所影响,并且也要影响迁移层(Transfer layer)的性质。迁移层的硬度是同与其紧挨着的基体材料形变后的硬度有关系。这一点很重要。这同瑞格内小组过去在铜铍合金上所作工作的结果是一致的。在滑动实验的最初阶段304~#～M_2之间的摩擦系数值同310~#～M_2之间的磨擦系数值是类似的,但随着滑动摩擦实验的进行,310~#～M_2之间的摩擦系数平缓地增长,并且最后稳定在某个值。而304~#奥氏体不锈钢在滑动摩擦实验的进行中形成了α′相形变马氏体,它使304~#～M_2之间的摩擦系数有很大的起伏涨落,但摩擦系数的平均值较低。
In a dry argon atmosphere, with metastable 304 ~ # austenitic stainless steel and steady state 310 ~ # stainless steel as a test block, M_2 tool steel as a trial ring, sliding wear on the LFW-1 ring block machine The wear surface and subsurface were observed and analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and scanning transmission electron microscopy (SEM). Combined with the measurement results of microhardness on the worn surface, In stainless steel, the formation of deformed martensite affects the formation and composition of the wear debris and also affects the properties of the transfer layer. The hardness of the migration layer is related to the hardness of the base material immediately below it. this point is very important. This is consistent with the previous work done by the Wrigley team on copper beryllium alloys. The coefficient of friction between 304 ~ # ~ M_2 and 310 ~ # ~ M_2 in the initial stage of the sliding experiment is similar, but with the sliding friction experiment carried out, the friction coefficient between 310 ~ # ~ M_2 The coefficient of friction increases slowly, and finally stabilizes at a certain value. While 304 ~ # austenitic stainless steel formed α ’phase martensite during the sliding friction experiment, which made the coefficient of friction between 304 ~ # ~ M 2 have a great fluctuation, but the average coefficient of friction Lower value.
