✦ Synopsis

To diminish wear in tribological systems is frequently to harden locally the load carrying areas, which are subjected to wear. A Nd:YAG laser was used for the improvement of hardness and wear resistance of steel U13A. The friction and wear characteristics of steel U13A in sliding contact against steel 65MN4 under unlubricated conditions were evaluated for conventional treatments and after laser irradiation. In addition, the transformations occurring during a laser treatments and the influence of laser parameters for quenching on Ž . tribological characteristics are presented. The experimental work indicates that wear resistance of steel U13A AISI W112 is higher at several times when compared to conventional heat treatments.
