Flux for the flux-cored wires was prepared by adding the equimolar mixture of TiC, NbC, VC and Mo 2 C powders to the Si-alloyed ferromanganese and arc shielding components. Microstructure investigations of the hardfaced layers show, that its structure consists of an austenitic matrix and complex carbide reinforcements, in form of uniformly distributed fine-grained particles. Its impact-abrasion wear resistance is more than three times higher than that for hardfacing, deposited with commercially available high-manganese steel-based electrodes and almost equal to the high-speed steel samples tested under the same conditions. © 2022 The Authors.
