Experimental study on laser surface texturing and wear characterization of titanium alloy

Creation of micro grooves, micro features, and micro textures in required dimensions are easily obtained by laser assisted micromachining technologies. This study focused to investigate the wear characterization of micro-textured Ti-3Al-2.5V alloy. Initially, surface textures were formed on the Ti alloy surfaces by fiber lasers. Surface textured specimens were subjected to wear studies in pin on disc tribometer to estimate the wear resisting capacity. Optical microscopy and 3D optical spectroscopy were used to analyze the waviness of the surface textures. After detailed texturing studies, the specimen is used for testing wear characterization which is done under dry sliding conditions. Load is the important characteristics which is followed by velocity and distance slide over the surface. SEM is used to investigate the details of structure and wear performance of the titanium alloy. The wavy laser surface texturing has greater impact on the wear resistance capabilities.
