The type of wear that pits metal is called?

Explanation:
Pitting is caused by corrosion, specifically pitting corrosion, which is a localized chemical or electrochemical attack that forms small pits in the metal surface. This differs from erosion, which is material removal by the flow of liquids or gases; abrasion, which is wear from hard particles sliding or scratching across the surface; and fatigue, which is damage from cyclic stresses over time. So the process that creates pits in metal is corrosion, not a purely mechanical wear mechanism. Pits can grow and lead to failure even when overall wear seems minimal.
