Abstract

The reliability of technical products is determined by their resistance to the influence of the external environment, the natural component of which are destructor microorganisms (bacteria, yeast, microscopic fungi, etc.). The low efficiency of protecting metals from biocorrosion is largely due to insufficient knowledge of all aspects of the damaging effects of microorganisms. There are no quantitative data on the processes of biodamage of equipment elements in real operating conditions. To date, reliable methods for diagnosing and predicting the durability of metals and their structures under conditions of interaction with wildlife have not been developed. In this work, an attempt was made to explain the role of biofilms of microscopic fungi as the important factor in the mycological corrosion of metals. The formation and accumulation of a corrosive medium is possible as a result of the metabolic processes of microscopic fungi that form a biofilm. A detailed determination of the mechanism of biocorrosion of metals is a complex scientific problem. The purpose of this article is to analyze experimental data on the study of aerobic biocorrosion of metals mediated by the metabolic activity of biofilms of bacteria and microscopic fungi.
