Abstract
The influence of chromium carbide, introduced into the furnace charge of surfaced flux-cored wire, on the wear resistance of the metal is considered. Arc surfacing was carried out in a shielding gas environment using experimental filler and electrode wires of the same composition. Chromium carbide, which is destroyed during surfacing, alloys the metal with chromium and carbon, which increases its wear resistance. It is established that the surfaced metal with a hypoeutectic structure with austenite and a maximum proportion of eutectic has the maximum wear resistance. Keywords: flux-cored wire, surfacing, metal microstructure, chromium carbide, wear resistance. aspankratov@bmstu.ru
