Abstract

The corrosion behavior of cartridge brass (UNS C26000) exposed to artificial seawater (AS) and Luria Bertani (LB) medium has been studied using electrochemical impedance spectroscopy. Tests were performed in sterile media and in the presence of a Bacillus subtilis bacterial biofilm. Additional tests were performed in the presence of a B. subtilis bacterial biofilm that produced polyaspartate or a B. licheniformis biofilm that produced β-polyglutamate. A significant reduction of corrosion rates and an ennoblement of the corrosion potential were observed in both media in the presence of the biofilms. Samples exposed in the presence of biofilms remained untarnished and unattacked for time periods exceeding one week, while samples exposed in the sterile solutions were covered with a dark film of corrosion products.
