Purpose: The comparison of thermal fatigue and mechanical properties of the hot work tool steels alloyed with carbide powders has been presented. The effect of laser alloying with powders on the surface layers alloying with HPDL was evaluated. Design/methodology/approach: In this paper the result of laser surface alloying is discussed. The material used for investigation were hot work tool steels X40CrMoV5-1 and 55NiCrMoV7 alloyed with TiC or TaC using high power diode laser. Findings: The thermal fatigue resistance measured with the average cracks deep subjected to steel alloyed with TiC powder is few times smaller compared to the steel after a conventional heat treatment, which was used as a reference material. The hardness value increases according to the laser power used in alloying. Research limitations/implications: It is necessary to continue the research to determine alloying parameters for demanded properties of hot work tool steels surface layers. Practical implications: The proposed new methods of enhancement fatigue resistant of hot work tool steels was the aim goal of this work. Originality/value: Laser alloying by using different carbide powders and HPDL laser is a new way to improve the structure and mechanical properties of the hot work tool steels.
