Abstract

The processing of laser hardening has been discussed. Paper presents a comparison of microstructure and mechanical properties (hardness and wear resistance) of three grades of carbon steels containing 0.15, 0.45 and 0.9% C after conventional and CO₂ laser hardening by melting and rapid solidification. Laser hardening of examined steels resulted in higher hardness and better wear resistance in comparison with conventional hardening. Post laser treatment tempering effected in carbides precipitation and further improvement in hardness and wear resistance.
