KINETICS OF THE ELECTROCHEMICAL OXIDATION OF ALUMINUM IN SULFURIC ELECTROLYTE

Abstract

It is investigated the kinetics of the growth of porous alumina by anodization in an aqueous solution of sulfuric acid. Kinetic data obtained as a result of the anodic process are extremely informative in terms of a general theory of pore formation in aluminum. It was observed to the existence of the «bifurcation point». The position the «bifurcation point» of for oxides molded at different current values has been defined.
