Application of Electric-Arc Pulsed Mode for Obtaining Surfacings of Fe_Mo_Cr_Ti_Ni_Cu_Al-System

[摘要] Method of electric-arc melting with nonconsumable electrode in a protective argon atmosphere with using a pulsed mode was used to show possibility in principle of obtaining multi-component metallic surfacing of Fe-Mo-Cr-Ti-Ni-Cu-Al system on uncooled steel substrate. Features of structure and elemental composition were studied using scanning electron microscopy methods. Component intermixing of the surfacing is observed. Surfacing microhardness is 5 times greater than that of the substrate. «Surfacing-substrate» boundary has high adhesion strength.
