The basis for limiting the durability of the internal combustion engine is the wear of parts of the cylinder-piston group and the crankshaft, which are characterized by the presence of small gaps between the plunger and the sleeve. High pressure is provided by the presence of small gaps between the plunger and the sleeve (at the level of 1-3 microns). The recovery method proposed by us is based on electrochemical technologies in polyethylene glycol-400 (PEG-400) electrolyte, which dissolves in water, has lubricating properties and fire-fighting ability, belongs to nonionic surfactants. It is necessary to establish the conditions for the formation of protective films on the friction surface of steel 20 according to LS59-1 using the lubricating properties of polyethylene glycol oils in conditions of unidirectional sliding friction. The presented mechanism of electrolytic transfer of constituent elements of alloys allows indicating the surface saturation of the cathode with one of its alloying elements, in this case from a copper alloy, without taking into account the limited difference in the electrode potential between the friction surfaces, taking into account the deformation component.
The main advantage of PEG-400 is its environmental friendliness, which is guaranteed by its chemical composition and solvent - water.
