Wear can be classified based on the ways that the frictional junctions are broken, that is, elastic displacement, plastic displacement, cutting, destruction of surface films and destruction of bulk material. There are many types of wear mechanisms, but we shall discuss about common wear mechanisms,
- Abrasive Wear : polishing, scouring, scratching, grinding, gouging.
- Adhesive Wear : galling, scuffing, scoring.
- Cavitation (interaction with fluid).
- Corrosive Wear (Chemical nature).
- Erosive Wear.
- Fatigue : delamination.
