Installations for producing electrospark erosion- and abrasion-resistant coatings on the blades of steam turbines of thermal and nuclear power plants

Abstract

This 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 KGB, developed and manufactured by the OAO VTI. A characteristic feature of the installations is the fact that they are equipped with electromechanical exciters with a high service life and reliability compared to electromagnetic ones. The study data for the electrical characteristics of the KGB-5 installation are presented.
