Moreover, a non-testing interval during an attrition-corrosion wear test can also increase the wear loss due to the generation of a thicker softened layer removed by the sliding antagonist once testing is resumed. It is also clear that only a limited number of attrition corrosion studies were reported, and very few of them investigated the underlying wear mechanism(s). Notably, Zheng et al. used LCSM to analyze the wear surfaces, while Wu et al. used FIB/SEM/TEM to analyze the wear surfaces/ subsurface.
