Abstract: Indentation tests on ceramic coatings are carried out in this paper and fracture pattern diagrams as a function of normal load and coating thickness are introduced for Al2 O3 and TiN coatings ...

Abstract: The three dimensional shape effect of asperity on abrasive wear was investigated with in-situ experiments in the scanning electron microscope. The geometry of model asperity was represented by ...

Abstract: Wear tests in dry rolling contact were carried out at room temperature on five ceramic materials, such as silicon nitride, silicon carbide, cermet, titania, and alumina. The results showed that ...
