ABRASIVE WEAR MECHANISM

, 2023
Wear - is a change in the size, shape, mass or condition of the surface of a product or structure due to destruction (wear) of the surface layer. Abrasive wear is the destruction of the surface by hard abrasive grains. There are two possible types of impact of abrasive grains on the surface.
