The effect of laser heat treatment (LHT) of selected steel grades after various chemical heat-treatments (CHT) on the structure and microhardness has been investigated. The specimens were subjected to following CHTs: boronizing (45), silico-boronizing (50HS) and chromizing (NC6). The LHT has been carried out by means of CO2 laser beam of maximum output of 6 kW and applied power 1200-2000 W at scanning rate 500 - 700 mm/min. Considerable refining and homogenization of the structure have been observed. It has been stated that LHT can eliminate the negative effects of the CHT (coarse grain and low hardness of the substrate).
