The paper considers the results of metallographic and tribotechnical tests of 20X13 steel samples and 20X13 steel samples with laser broadband cladding with 20X13 powder. The deposited layer had a dendritic differently oriented structure. The microhardness of the coating was 501–575 HV. It was found that the wear rate of the cladded coating is 3.16 times lower than that of the base material. The wear rate of the counter sample made of hardened steel 45 was lower in the friction pair with the cladded sample compared to the base material. The average friction factors for the cladded samples were 0.043, and for the base material was 0.078. The performance of broadband laser cladding is 5–7 times higher than when processing with a defocused beam.
