Purpose: Improvement of surface properties of X38CrMoV5-3 is one of the goals set to the research institutions active in this paper. Design/methodology/approach: Remelting and alloying of surface layers were made using the HPDL high power diode laser Rofin DL 020 in the laser power range of 1.2-2.3 kW. Abrasion wear resistance tests were made in the metal-ceramic material arrangement (ASTM-G65), and also in the metal-metal one. Findings: All employed carbides cause hardness and microhardness increase of the surface layer of the investigated steel, and in most cases abrasion wear resistance increase. The investigations carried out indicate that the best mechanical properties are displayed by the surface layers of steel alloyed with carbides: TaC, NbC, and VC; whereas, the best tribological properties are displayed by surface layers allowed with vanadium carbide, compared to the conventionally heat treated steel. Improvement of mechanical properties and abrasion wear resistance grow with the increase of the laser power. Research limitations/implications: The material behavior for the HPDL processing has been found to be different from the other high-power lasers in the following aspects: fewer cracks and less spallation for surface glazing/sealing, more uniform melt/heating zones, smoother surface, better beam absorption for metallic materials, more consistent and repeatable. Practical implications: The research results indicate to the feasibility and purposefulness of the practical use of remelting and alloying with the tungsten carbide using the high power diode laser for manufacturing and regeneration of various tools from the X38CrMoV5-3 hot-work tool steel. Originality/value: Possibilities of increasing the functional properties of hot-work alloy tool steels by modification of their chemical composition additional of ceramic particles in a conventional way are very limited already.
