N2 - This article presents the results of laser treatment influence on structure and properties of the surface of the 32CrMoV12-28 hot work steel, using the high power diode laser (HPDL) for remelting and alloying. In this work structure changes as well as hardness are investigated, also phases occurred in the surface layer were determined. The goal of this work was also to determine technically and technological conditions for remelting of surface layer with HPDL. This study was conducted to make clear an effect of niobium and tantalum carbide, NbC and TaC addition and the influence on structure and properties of the laser remelted metal surface. Investigations carried out allow to conclude, that as a result of heat-treatment as well as of remelting of the hot work steel 32CrMoV12-28 with TaC and NbC powder high-quality top layer is possible to obtain. The layer is without cracks and defects as well as has a considerably higher hardness value compared to the non remelted material. The hardness value increases according to the laser power used so that the highest power applied gives to highest hardness value in the remelted layer.
