On the Methodology of Strengthening and Restoration of Functional Surfaces of Machine Parts, of Improving their Efficiency, and of Criteria of their Assessment at Electrospark Alloying. Part 1: Research Methodology and Receiving Electrospark-Alloyed Coatings

The work is devoted to achieving the required functional properties of the functional surfaces of various objects: machine parts and technological equipment, tools for mechanical processing of materials in the cold and hot state, by processing them by the electrospark alloying (ESA). The aim of the work was to develop a methodology for getting functional surfaces of components for various purposes by applying ESA and to justify the criteria and parameters for evaluating this method. In the first part of the investigation, a number of methodological schemes related to obtaining functional ESA coatings are considered. The main methodological provisions for hardening and restoring the functional surfaces of various objects from conductive materials using ESA are considered, taking into account their functional purpose and the important role of the anode material in interrelation with the cathode material in the process of creating functional coatings
