Abstract

A cylinder-on-plate reciprocated sliding testing machine and a tension-compression testing machine were used to compare the wear, tension, and fatigue performance of specimens with Ti base and Cr base coatings grown by physical vapour deposition. Fracture mechanisms were examined using a scanning electron microscope and an optical microscope. The experimental results show that the Cr base coatings possessed far better wear resistance than the Ti base coatings. The application of surface films did not affect the Young's modulus and yield stress but did decrease the fracture strains somewhat. In the case of fatigue, the application of the surface coatings extended the endurance limit by 20-40 MPa.
