The development of criteria for evaluating the effectiveness of the surface layer formation and its properties in the process of electrospark alloying (ESA). Part 2. The criteria of the effectiveness of the ESA process and electrospark coatings

The paper offers comprehensive and integrated specific criteria for the effective use of electrospark alloying (ESA) to determine the effectiveness of the conditions of applying electric-spark coatings with the required performance characteristics and parameters of the surface topography, taking into account the energy costs. A general criterion is also provided for the efficiency of the coating, allowing us to determine and compare the performance of different coating processes by ESA and other methods based on energy consumption, and economic and environmental factors.
