Abstract: The relevance of the topic of the presented article is due to the constant development of technologies for repairing and restoring machine parts. Currently, the technology of restoring piston pins of internal combustion engines (ICE) is actively used using a high-energy method of plastic deformation of metal based on an electrohydraulic effect, which is the use of energy from a high-voltage pulsed discharge in a liquid. The article examines approaches to improving the efficiency of the process of restoring piston pins of the internal combustion engine by introducing the method of electrohydraulic distribution. The influence of the electrical parameters of this process on the amount of deformation of piston pins, depending on the material used, is analyzed. A mathematical model of the interaction of a shock wave with a material is also considered, which allows a deeper understanding of the mechanisms underlying this recovery method.

Keywords: restoration, piston pin, electrohydraulic distribution, wear, repair size, electric discharge, plastic deformation of metal, electromagnetic energy, energy of explosives.
