Wear

By subjecting a material to frictional forces over several cycles, material is removed from a controlled location. After sufficient cycles, enough material has been removed from the sample surface to have a measurable difference from its original state. The wear track produced from the reciprocating wear test can be analyzed under methods like scanning probe microscopy to retrieve material loss through wear. Reciprocating wear analysis can give an estimation of the useful life of a material by measuring the material removal rate. Reciprocating wear testing is useful for analyzing very small amounts of material removal like thin film coatings.
