This work demonstrates the evolution of surface topography with the number of cycles during running-in wear. The Archard’s wear law is employed to simulate the wear depth by assuming the linear elastic behavior of materials. The numerical simulation is performed on various 2D profiles with varying RMS roughness, skewness and kurtosis. It is shown that roughness parameters significantly change with the number of wear cycles. Two different wear rates are clearly shown which correspond to running-in and mild or steady wear rates. The proposed wear model is developed for dry contacts. Furthermore, it can be extended to develop more complex wear models.
