Metallographic examination of metal, surfaced by shots of high-chromium cast iron in current-carrying mould, was carried out. It was established, that in spite of peculiar conditions of formation of metal pool in this case, the structure of periphery zones of deposited metal are not greatly differed from the structure, formed at ESR in conventional water-cooled mould. To produce the homogeneous structure of the deposited layer without the presence of non-melted metal inclusions in it, it is necessary to select the surfacing electric modes with account for a mass speed of shot feeding and its fractional composition.
