| Abstract | Material wear widely exists between contact surfaces with relatively sliding. Conventional studies generally focus on specific materials, limiting the universality of wear laws. In this paper, we studied the wear rate across various materials through nanoscratching simulations. These materials are characterized by model materials with modified Morse potentials and real material of copper. Our findings indicate that wear rates decrease with increasing sliding velocity. This velocity dependence of wear is attributed to the rate effect of plasticity, which influences wear volume and contact force at varying velocities. In addition, interfacial adhesion plays a significant role in this velocity dependence. There exists a critical adhesion ratio beyond which the wear rate stabilizes for both low and high sliding velocities. Notably, we quantified the rate effect of wear by an analytical expression developed in this study. The results revealed that materials with similar hardness-to-modulus ratios exhibit analogous velocity dependence in wear, characterized by comparable power exponents. Our findings enhance the understanding on velocity dependence of wear rate for contact surfaces across distinct interfacial and material properties. |
