Abstract

The invention relates to the technology for electrochemical protection of metals in natural and artificial environments, namely to electrodes used as anodes for cathodic protection of underground metallic structures from corrosion.Summary of the invention consists in the formation of a slightly soluble surface layer on a workpiece of plain carbon steel. The process includes electroplating deposition on the workpiece of an intermediate nickel layer of a thickness of 110…150 µm, and then, by electric-spark alloying method, formation of a surface layer consisting of titanium-nickel intermetallides, corresponding carbides and graphite, with a total carbon content of 6…11 mass % by weight of the surface layer.The result is to reduce by about 2.1 times the cost of manufacture of slightly soluble anode on a steel substrate, compared with the prototype on a titanium substrate, while maintaining the anode high resistance against chemical and electrochemical corrosion.
