摘要：
Laser treatment of surfaces to improve their wear resistance was under the study. Specimens, made of plain carbon steel C45, tool steel Arne, PM steels Vanadis6 and Weartec (R) were laser hardened. HVOFS WC-17Co coating and PVD deposited TiN coating on steel substrates were treated applying CO2 laser radiation, varying scan speed and power. The treated specimens were subjected to microhardness measurements and wear block-on-ring rubber wheel tests. The results of laser treatment showed that the microhardness values increased significantly in comparison with a conventional heat treatment. The wear resistance of all treated surfaces was lower, than in the case of conventional heat treatment methods.
