Abrasion
Definition
A complex process of mechanical wearing down, erosion, grinding, or polishing of a solid surface (rocks, metals, industrial materials) through repeated friction with hard particles or abrasive bodies; (in geology) the destructive erosive action on sea or large lake shores exerted by the violent movement of waves and transported debris; (in medicine/dentistry) progressive pathological loss of hard dental substance or skin tissue (superficial scratch, graze) caused by external mechanical frictional factors.
