Difference between Wear and Abrasion | Wear vs Abrasion

Key Difference: Wear is the loss of material from the surface of a material. This process is generally progressive in nature. Abrasion is one of the actions which can cause wear. It is caused by the mechanical process of rubbing the surface against some other material. Wear and abrasion are often considered to be the same.

Abrasion & Corrosion - Pump School

Evidence of corrosion is different from indicators of abrasion. Corroded parts show even wear and possibly some pitting (Photo 1). Abrasion, however, causes uneven wear that follows the mechanics of the pump. On the outside diameter of a gear, for example, wear causes a scoring along the path of rotation (Photo 2).
