What is the difference between adhesive wear and abrasive wear?

The key difference between these two wear mechanisms is that adhesive wear involves material transfer due to adhesion, while abrasive wear involves material removal due to the action of harder particles or surfaces. Adhesive wear is common in metal-to-metal contact situations, like in bearings and gears, whereas abrasive wear is frequently encountered in environments with hard particles, such as mining, drilling, and machining operations.
