Influence Factors to The occurrence of abrasive wear

Wear, It can happen on its own or be caused by contact with another surface. Abrasive wear takes place when a rough, hard surface glides across a surface that is relatively softer.
There are several factors that influence the occurrence of abrasive wear and the way a material is removed. Various mechanisms are used to define the way the material is eliminated. The three major mechanisms related to abrasive wear are:
Fragmentation - This takes place when a certain material is separated from a façade through a cutting process. This results in indenting abrasive that can cause localized fracture within the wear material. Cracks spread freely throughout the wear, leading to further material removal.
Cutting - This occurs when a material separates from a surface in tiny chips or debris, with only minimal or no displacement to both of the groove sides. This is similar to conventional machining.
Plowing - This occurs when there is material displacement sideways, moving away from the particles of wear. This results in groove formation that does not involve removal of material. The displaced material creates ridges along the grooves that may be eliminated by consequent abrasive material passage.
