The wear rate is affected by factors such as type of loading (e.g., impact, static, dynamic), type of motion (e.g., sliding, rolling), temperature, and lubrication, in particular by the process of deposition and wearing out of the boundary lubrication layer. Zobacz więcej Wear is the damaging, gradual removal or deformation of material at solid surfaces. Causes of wear can be mechanical (e.g., erosion) or chemical (e.g., corrosion). The study of wear and related processes is referred to as Zobacz więcej Under nominal operation conditions, the wear rate normally changes in three different stages: • Primary stage or early run-in period, where surfaces adapt to each other and the wear-rate might vary between high and low. Zobacz więcej The Reye–Archard–Khrushchov wear law is the classic wear prediction model. Zobacz więcej • Abrasion (mechanical) – Process of wearing down a surface • Backlash (engineering) – Clearance between mating components • Hysteresis – Dependence of the state of a system on its history Zobacz więcej Types of wear are identified by relative motion, the nature of disturbance at the worn surface or "mechanism", and whether it … Zobacz więcej Several standard test methods exist for different types of wear to determine the amount of material removal during a specified time … Zobacz więcej Wear coefficient The wear coefficient is a physical coefficient used to measure, characterize and correlate the wear of materials.
