The article is devoted to the creation of installations for generating electric spark erosion and abrasion-resistant protective and strengthening coatings on the blades of steam turbines of thermal and nuclear power plants such as GBF and the KGB, developed and manufactured by the JSC "VTI". A feature of installations is that their beeing equipped with electromechanical exciters with a high performance and reliability of the resource compared to electromagnetic ones. The data from the study of electrical characteristics of the installation KGB-5 are presented.
Keywords: electrical discharge coating, abrasion resistant coatings, erosion resistant coatings, steam turbine blades, trailing edge of the blade, front edge, thermal power plant, nuclear power plant, electrospark discharge, exciter, pulse discharge.
