This study evaluates a new surface finishing process called laser-assisted turning. WC-CoCr coatings were produced by HVOF spraying and characterized based on surface morphology, microstructure, and friction and wear properties. The coatings were then treated using the new process and re-examined and tested. Surface roughness and hardness were significantly improved, although friction and wear properties were found to be inferior to those of WC-CoCr coatings finished by grinding and polishing.
