DEVELOPMENT OF A METHODOLOGY FOR IMPROVING THE TRIBOLOGICAL PROPERTIES IN DIE PROCESSING USING LASER SURFACE TEXTURING

摘要

The purposes of this investigation were to measure the positive effects in the lubrication through the application of micro textures made by laser (Laser Surface Texturing). Different types of micro textured patterns were studied, which vary in the quantity of micro cavities, micro cavity diameters, depths of micro cavities, and surface density attacked by micro cavities. It was found that, compared with plain steel surfaces, laser texturing significantly reduces friction and wear.
