Abstract

Process of electrochemical corrosion is considered for the technological equipment in decontaminating solutions of poison matters. It is shown, that corrosion of steel occurs according to the electrochemical mechanism with hydrogen depolarization in a solution of phosphoric acid. Corrosion of steels occurs with oxygen depolarization in organic and alkaline solutions with much smaller speed, than in a acid solution. Rate of corrosion sharply increases by contact of diverse metals in an aggressive environment because of work of a short-circuited galvanic cell. 

Key words

corrosion, depolarization, equipment, solution, assimilation, elements, potential, rate, steel, test.
