INVESTIGATIONS OF MORPHOLOGY AND CHEMICAL COMPOSITION OF ELECTRO-IMPULSE POLISHED SURFACE OF CARBON AND CORROSION-RESISTANT STEEL

Abstract

The paper presents results of the investigations pertaining to morphology and chemical composition of thin surface layer of structural carbon and corrosion-resistant steel after the process of electro-impulse polishing. It has been established that removal of metal being polished occurs due to anode processes on the treated surface that leads to formation of surface films that can have different nature and thicknesses. The paper reveals that under conditions of electro-impulse polishing anodic dissolution of steel takes place with direct participation of anions of electrolyte solution.
