ALUMINUM CORROSION PROCESSES IN MICROBIAL CULTURES

Abstract

The paper presents data to support the concept that microorganisms can produce corrosion of 2024 and 7075 aluminum alloys by two mechanisms: (1) removal of a corrosion inhibitor, nitrate, from the growth medium and (2) production of metabolic products in the medium. Results are presented to show that nitrate is a good inhibitor of CaCl2 corrosion of aluminum alloys and that nitrite, one of the metabolic products formed from nitrate by the microorganisms, is not an inhibitor of CaCl2 corrosion of aluminum alloys.
