Abstract

The selection and use of wear tests for coatings are discussed. Coated materials are vastly different and more complicated than uncoated or monolithic materials. It is therefore necessary to characterize the coating and the coating/substrate interface in terms of physicochemical and mechanical properties. Wear is a multi-faceted phenomena. Various tests used to study the wear properties of coatings are described. They include tests for adhesive wear, abrasive wear, impact erosion wear, and fatigue wear.
