Explanation

It refers to the phenomenon that when a hard rough surface or abrasive slides relative to a soft surface, a series of grooves are drawn on the soft surface and materials is lost. The wear between two surfaces is called three-body abrasion. A part surface only slides with abrasive or with another rough surface to produce wear, which is called two-body abrasion. The former abrasive is active; The latter, such as a rough surface, is fixed. According to the action characteristics of force, abrasive wear can also be divided into: ① chiseling wear, that is, abrasive impacts the surface of parts under high stress, chiseling off large pieces of materials, such as jaw crusher tooth plate wear by ore; ② Abrasive wear, that is, the abrasive is crushed and causes wear on the surface of the parts, such as wear of the ball mill liner and ball when grinding ores; ③ abreaded wear refers to the wear caused by scratching on the surface of parts during the sliding process when the stress is low and the abrasive is generally not broken. abrasive wear can be dry or wet, and may occur with or without lubrication.
