Corrosion inhibitors are the only most widely applied method for corrosion protection of metallic materials and are of particular importance in industry. Nowadays, the synthesis of corrosion inhibitors using traditional multistep reactions is highly restricted because of the increasing demands of "green chemistry". Plant materials and biomass wastes are ideal green candidatures to replace traditional toxic corrosion inhibitors. Literature survey reveals that different extracts of the plant and agro-food wastes contain naturally phytochemical compounds which have antioxidant properties have been effectively employing as sustainable inhibitors for the corrosion of different metals and alloys. Nevertheless, despite the numerous research papers, the reviews in which the correlation between the antioxidant/free radical scavenging activity of the extracts and their inhibition action is explained are not represented in the literature. This paper provides a brief overview of current knowledge in what kind of methods are used to estimate the antioxidant content, which classes of compounds provide higher antiradical activity and poses questions that we need to answer in order to use parameter of the antioxidant activity as a predictive index for performance evaluation of the plants/biomass wastes extracts as corrosion inhibitors. The conclusion is that no single mechanism of antioxidant actions and anticorrosive protection is operative in plant/wastes extracts. The high inhibitory efficiency is predicated on a number of complementary processes working holistically. By developing the theoretical basis and mechanism of action between the anticorrosive and antioxidant properties of plant extracts, it is possible to create predictive tools for selecting plant extract and further obtaining anti-corrosion protection based on it.

Triazoloazepinium bromides act as biocides against sulfate-reducing bacteria and can produce an effect on mild steel microbial corrosion. It has been established that under the competing adsorption, the compounds with the properties of corrosion inhibitors can form a film, which protects the steel surface, before it is settled by corrosively active microorganisms.The protective film ensures the inhibition efficiency of up to 98.7%. With triazoloazepinium bromides of the 2nd group, corrosively active microorganisms colonize the steel surface before the inhibitor creates the protective layer. In this case, the biocorrosion accelerates by up to 6.25 times. Different effect of triazoloazepinium bromides on steel biocorrosion rate is explained by the molecular structure.

“…One of the most dangerous types of microbial corrosion is the destruction of metal constructions under the influence of sulfate-reducing bacteria (SRB), which reproduce actively in the biofilm under anaerobic conditions [8,9]. To protect the metals against the microbial corrosion, the inhibitors-biocides are used, which can inhibit functioning of corrosively active bacteria, sulfate-reducing bacteria in particular, and decelerate the rate of metal microbial corrosion.…”

The paper describes the synthesis of a set of new 2,3-dihydroimidazo[1,2-a]pyridinium bromides which demonstrate antibacterial properties against sulfatereducing bacteria of Desulfomicrobium and Desulfovibrio strains and inhibit their functioning in the binary culture under the steel microbial corrosion. The compounds demonstrate antibiofilm and anticorrosive properties in the medium with sulfate-reducing bacteria, steel anticorrosion rate is up to 70.6 %.
