Implemented a combined surface treatment of steel Hardox 450, is to form layer of electro-contact method, weld powder wire composition of Fe-C-V-Cr-Nb-W, and its subsequent irradiation of high-intensity pulsed electron beam (EBT). Submitted tribological test modified surface and showed an increase of 32.5 times the wear resistance of the irradiated layer compared to the base material. By transmission and scanning electron microscopy studies carried out elemental and phase composition, the defect substructure of steel Hardox 450 and the surface layer deposition, the modified EBT. It is shown that electron-beam treatment of the surface of the deposited layer is accompanied by the formation of a multilayer structure. The interfaces identified layers contain micropores and microcracks, which indicates a high level of compatibility. Revealed the formation of EBT in modified layer multiphase structure represented by α-phase and carbide phases based on niobium, chromium and iron. EBT of the deposited layer surface leads to a drastic decrease the size of the inclusions located both in the modified layer and the deposited metal mainly volume. Prior to EBT inclusions average size of 2.5 µm after the irradiation - 0.6 µm. Deposited metal layer subjected to EBT is in elastically-stressed state, as evidenced by the presence of numerous extinction contour bending, secretions present in the carbide phase. It is shown that the high-speed hardening of the deposited layer, which is realized when it is irradiated with EBT, accompanied by the formation of martensite package with ultra low transverse (40-70 nm) dimensions of the martensite crystals.
