HW 6, Problem1
Make a table listing all possible alternative wear mechanisms that can be expected in metallic materials
used in engineering applications and include a brief description of the physical and/or chemical
processes involved.
Wear Mechanism
Adhesive Wear
Abrasive Wear
Diffusive Wear
Chemical Wear / Corrosion
Erosive Wear
Contact Fatigue
Fretting
Adhesive Wear
Phenomenon that occurs when two or more metallic bodies of distinct wear resistances rub together
such that the body with the least resistance loses material. The extent of material loss depends on
physical and chemical factors such as material properties, corrosive environment, and dynamics such as
velocity and applied loads.
Abrasive Wear
This type of wear occurs when a rough body slides over a softer body
