Mikrobinė metalų korozija natūralią aplinką imituojančiomis sąlygomis / Microbic corrosion of metals under accelerated test conditions

Corrosion behaviour of Al, Zn, Cu and steel samples under the conditions of constant temperature and humidity were performed in the media containing the following microorganisms. Bacillus mycoides, Aspergillus fumigatus Aspergillus niger, Cladosporium herbarum, Penicillium frequentans. The influence of metal surface morphology on the vitality of microorganisms was investigated, as well as the proceeding of microbial corrosion was under the study. The real surface area of Cu electrode was determined by means of electrochemical techniques, while the method for comparison of surface areas of other metals was proposed and this method was based on atomic force microscope measurements. It was determined that the metal nature and morphology influenced the vitality of microorganisms. The results of electrochemical impedanse spectroscopy enabledus to evaluate the corrosion behaviour of metals. The results were found to indicate the corrosion inhibition for Al, steel and Cu, however, the effect depended on the metal surface morphology and exposure time.
