Abrasive wear is a type of material loss that occurs when hard particles or surfaces slide against softer materials, causing scratches or grooves. This process can happen in various environments, such as in machinery, where moving parts come into contact with each other, or in natural settings, like soil erosion. Common examples of abrasive wear include the wear of metal components in engines and the degradation of road surfaces due to vehicle traffic. Factors influencing abrasive wear include the hardness of the materials involved, the presence of lubricants, and the speed of movement between surfaces.
