摘要：
The influence of Pseudomonas aeruginosa on the corrosion resistance of 304 stainless steel in neutral buffered solutions containing 0.5 M NaCl was studied by using potentiodynamic and potentiostatic techniques complemented with scanning electron microscopy. Results showed that the growth of Pseudomonas aeruginosa in the medium decreased the resistance of the localized corrosion of 304 stainless steel specimens. This effect can be explained by the formation of microcrevices under the biological deposits and by passive film thinning due to the production of aggressive metabolites.
