ABRASIVE WEAR MECHANISM

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. Hydrabrasive wear change the size, shape, mass or condition of the surface of a material under the influence of a moving liquid with inclusions of solid matter distributed throughout its volume. The intensity of hydroabrasive wear depends on the quality of the wear material, size, shape, hardness, density of solid particles of the hydraulic mixture, its concentration, density, viscosity, corrosiveness of the liquid medium, speed of movement of particles relative to the wear surface, angle of approach to the surface, etc.
