FIELD: corrosion and electrochemistry; relative estimation of pitting resistance of chromium-containing metal materials of all types ( metallic chromium, stainless steels, amorphous alloys, chromium carbides at predicting corrosion resistance and at selecting structural materials). SUBSTANCE: method involves determining electrode potential of anode curve active branch inclination and corrosion rate in solutions of chromium halide salts and determining pitting resistance as parameters correspond to uniform corrosion occurring at pitting bottom. EFFECT: enhanced accuracy and efficiency. 1 tbl
