Abstract

Improvements in tribological properties of physical vapour deposited (PVD) ceramic coatings were studied. The ratio of hardness to elastic modulus was sited as an important parameter in optimizing the wear performance of the coatings. The wear resistance increased with decreasing elastic modulus for materials of similar hardness. Hardness to elastic modulus ration provided a close correlation with relative wear resistance and was used to rank materials. Equations were developed to indicate that the resistance to crack propagation improved if material possessed high elestic modulus.
