The paper presents the results of metallographic and tribotechnical studies of the samples of 20Kh13 steel alloyed with Fe-­Cr-­V-W-Mo powder using a laser beam and with the addition of 5 vol. % nano-powder of tantalum carbide to the charge. Elemental analysis showed that the alloying elements in the charge are distributed evenly over the depth of the layer. Transverse oscillations of the laser beam led to an increase in the productivity of the laser alloying process. The analysis of the tribotechnical tests tesults revealed that the alloyed layers had lower friction coefficients when adding tantalum nano carbides to the charge, and higher wear resistance compared to the main charge and the initial steel.
