Abstract
The article presents the results of research on technology development and substantiation of the modes of strengthening the working surfaces of earth-moving machines by the electromechanical method. The types of wear and the appearance of defects on the working surfaces of the part are analyzed, taking into account the operating conditions. Based on the conducted studies on the study of surface wear, the arithmetic mean values were determined using the example of a plowshare of a bulldozer blade. A technology for restoring a part with subsequent electromechanical hardening has been developed. The influence of processing modes on the surface hardness was studied, and using a multifactorial experiment, a regression equation was identified, and optimal hardening modes were substantiated.
