Abstract: The contact mechanisms of a transfer layered surface during sliding wear of a Si3 N4 ball against the amorphous carbon film were investigated. In this study, amorphous carbon films were deposited ...

Abstract: The critical conditions (critical stress and critical temperature) for the demagnetization of perpendicular magnetic recording disks were investigated. A tribo-demagnetization test of a perpendicular ...

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 local yield maps for the identification of the yield initiation positions of hard coating on three-dimensional (3D) elastic half space under sliding contact were developed. In this study, ...
