Influence of Laser Surface Texturing Distribution Patterns on the Hydrodynamic Lubrication
Laser Surface Texturing (LST) is an advanced method of surface micro-texturing technology. The aim of this paper is to investigate the influence of laser surface texturing distribution patterns on lubricant characteristics for laser texturing surfaces against cylindrical under conditions of film lubrication. The laser texturing surfaces are processed with power levels under YAG laser. Under conditions of constant depth and area coverage ratio of LST,patterns of the texture distribution and the sliding orientation relative to the texture were systematically varied. The experimental results suggested that 20° circumferential interval can increase the load-carrying ability of lubricating film.
