Abstract

This review is devoted to an analysis of plasma electrolytic saturation of steel and titanium alloys with light elements (nitrogen, carbon, and oxygen). These technologies have a number of advantages because of the high rates of processes and the low cost of equipment. Electrochemical aspects of the process, which include the formation of a gas–vapor shell, its composition, processes of anodic dissolution, and oxidation and adsorption of a saturating element on the surface processed, are considered. Data of investigations of the mechanism of the release and transport of nitrogen and carbon from the electrolyte into metal are given.
