Abstract Material wear between contact surfaces with relatively sliding can be related to the failure of elevated asperities at small scales. The asperity wear depends on various factors, including material properties, interfacial adhesion, and friction velocity. In this study, using a series of materials characterized by the modified coarse-grained potentials, we studied the rate effect of adhesive wear at the asperity level over a wide range of plowing conditions. The results showed that increasing plowing velocity leads to the transition of the wear mechanism from plasticity-induced asperity smoothing to the formation of fractured debris and thus breaks down the Archard wear… More >
