Influence of geometry and the sequence of surface texturing process on tribological properties
2017
Abstract The aim of this study was to investigate the influence of geometry and the sequence of surface texturing process on tribological properties of contact surfaces. Textures in the form of pyramid, cone and concave shape were introduced before and after hard TiAlN coating deposition. Textures with pyramidal shape resulted in the worst tribological behaviour, while laser textures provided the best results. It was found that the sequence of surface texturing has an effect on tribological behavior. If texturing is done after coating deposition, friction is lower regardless of the texturing type because of the better wettability of steel in comparison with coating.
