The research is aimed at developing a rational technology for restoring worn-out sections of the working surfaces of MT-140 bead mill screw segments and increasing their operational life. Worn segments made of ChKh1 grade gray chromium cast iron served as the research material. For restoration, the technology of arc hardfacing with flux-cored wires of SK A43-O, VELTEK N-590, VELTEK N-290, and Supershield CrC grades was applied. Hardfacing was performed in two layers with different bead orientations using a Lorch Micormig 350A semi-automatic welding machine at I = 200 A and U = 30 V, with pre-heating to 400…450 °C. The best wear resistance values are demonstrated by high-alloy wires SK A43-O and Supershield CrC due to the formation of a significant fraction of hard chromium and niobium carbides. It was confirmed that no proportional relationship between the hardness of the hardfaced layers and their wear resistance is observed. It has been established that the orientation of the surfacing rollers along the segment radius affects the wear intensity of the working surface of the part. For the restorative surfacing of segments, it is proposed to use flux-cored wires, which ensure the formation of either a hard carbide framework or a plastic matrix in the deposited layers, which are capable of providing increased resistance to combined cavitation and hydroabrasive impact. 17 Ref., 3 Tabl., 8 Fig.
