FIELD: electrochemistry, namely manufacture and restoration of steel articles by applying onto them strengthening and protective coatings by electrodeposition.
SUBSTANCE: process comprises steps of applying onto article aluminum film with thickness 20 - 50 micrometers in formamide electrolyte with use of aluminum node; washing out article in distilled water; micro-discharge oxidizing of article by means of alternating current in alkali electrolyte with use of electrode of corrosion resistant steel.
EFFECT: enhanced strength of cohesion of oxide coating with steel base of article.
