Abstract

The technique of laser texturing has been gaining popularity in recent years because of its use in enhancement of tribological performance. In this paper, the effect of indirect laser texturing is analyzed on hydrogenated DLC coating under line contact configuration. Most previous research studies have been carried out for point contact configuration. The aim of this study is to investigate the effectiveness of indirect laser textured DLC for cam/tappet contact in an engine. For this reason, this study focuses on line contact. The tribological performance of textures is dependent on their geometric parameters. Therefore, textures' diameters and densities were varied. The results indicated that at a diameter of 50-μm and 20% density, tribological performance of a cylinder on a coated plate tribo-pair can be enhanced.
