This paper was devoted to the experimental study of coaxial laser cladding during repairing of the parts made from tool steel such as boring tools, forming rolls, stamping punches, dies, etc. The goal of the study was achievement of the possibly best quality of cladded layers due to high demands of wear resistance and durability of the mentioned parts. The experimental part of the study was based on varying of technological parameters of the laser cladding process. The mechanical properties of the achieved cladded coatings were evaluated by hardness measures and wear test using a ball-on-disc type tribometer according to the tribology standards ASTM G99, DIN 50324. The friction coefficient and wear rate of a counter-body was determined at 3 N load at 0.05 m·s-1 linear speed. The result analysis of the experimental study and testing of the created coatings allow concluding that the goal of the study was achieved, i.e. the combination of the technological parameters, which guarantee high functional properties of the coating, was found. Additionally, the isotropy of the tested properties was revealed.
