USE OF PROCESSES OF ELECTRO-SPARK PROCESSING TO ENSURE THE DURABILITY OF HYDRAULIC EQUIPMENT UNITS OF AGRICULTURAL EQUIPMENT

Abstract

The modern concept of effective use of machines and equipment consists in the development of technologies and means of increasing their durability due to the creation of coatings that ensure the specified functional properties of the working surfaces of components and aggregates. In this regard, the research, development and improvement of technologies for obtaining surface layers with a given structure and, accordingly, the necessary properties, is an urgent task. At the same time, it is necessary to take into account that the energetic ability of the interaction of the saturating element, the physicochemical nature of the saturating medium, and the mechanism of phase transformations are of decisive importance in the formation of the layer structure. The technological support of wear resistance of metal surfaces on the basis of electrophysical methods of strengthening and restoration using high-energy concentrated energy flows opens wide prospects. In repair production, methods based on the use of energy flows with a specific power in the heating spot of more than 102 W/mm2 are widely used to restore and strengthen parts.
