It is shown that the structure of metal padded with powder wire having the following mixture: 15% Cr – 0,5% B4C – 0,5% BN – 2,5% TiB2 – 1,0% ZrB2, is a martensitic matrix with (Fe, Cr)2B boride eutectic, carbon boride of (Fe, Cr)7(C, B)3 type and ε –(Fe, Cr)2-3N nitrides. Such a wire can be used for strengthening weld deposition of parts operated under conditions of heavy friction loading.
