“…At high rotation speed, the zinc oxide (ZnO) film of galvanized steel, formed by tribochemical reactions on the contact surface, is broken, allowing the material removal from the contact surface. 61 This behavior is associated with the slip speed, a determining parameter for the transition from severe to light wear. 62 The wear regime and consequent mass removal are related to the sliding speed and other agents such as the a lubricant, material properties, geometry, surface finish, and interfacial elements.…”
