The paper presents the results of a study aimed at ensuring the maintainability of crankshafts, as well as the importance of the need to restore worn crankshaft journals, an analysis of existing methods and an innovative method developed by the authors. The essence of which lies in the fact that each neck of the shaft is subjected to copper plating by contacting at the moment of rotation with a swab dipped in a solution of copper sulphate in water and in an electrolyte. Then, on each neck, plates obtained by rolling from a mixture of brass powder and powders of hard alloy materials (tungsten carbides, titanium, etc.) are mounted by wrapping around the neck, with layers of pasty flux from borax, brass powder, and soldering fat deposited on their surface. Further, with the help of a detachable inductor fixed in the tool holder of the machine, each neck is subjected to heating in turn. Moreover, when the inductor is turned on, a low frequency is first used to increase the depth of heating, and then the frequency increases.
