【 摘 要 】

Structure-phase state and tribological properties of the coating deposited on Hardox 450 martensitic low-carbon steel by flux-cored wire Fe-C-Cr-Nb-W and modified by subsequent electron-beam processing were studied. It is shown that the electron beam processing of ∼ 5 mm thick deposited layer leads to the formation of ∼ 20 μ m thick modified surface layer with the main phases of α-Fe and NbC, Fe3C and M6C(Fe3W3C) carbides. Wear resistance of the weld layer is 70 times higher than the one of the original steel.
