Development, application and evaluation of the Laser Surface Texturing (LST) process in tooling for the metalworking industry

•In this research the effects of tribological performance through the implementation of
microcavities by applying Laser Surface Texturing (LST) technique on tool steel for metalmechanic industry are evaluated
• The study is performed by varying the microcavities’ geometries and lubricant type (water-based or oilbased). PVD coating was introduced as comparison.
• For tribological evaluation, a block-on-ring configuration was used.
• The experimental design parameters are proposed and evaluated to identify the best
tribological performance (coefficient of friction – COF and wear).
