Organic Corrosion Inhibitors

Corrosion control of metals is technically, economically, environmentally, and aesthetically important. The best option is to use inhibitors for protecting metals and alloys against corrosion. As organic corrosion inhibitors are toxic in nature, so green inhibitors which are biodegradable, without any heavy metals and other toxic compounds, are promoted. Also plant products are inexpensive, renewable, and readily available. Tannins, organic amino acids, alkaloids, and organic dyes of plant origin have good corrosion-inhibiting abilities. Plant extracts contain many organic compounds, having polar atoms such as O, P, S, and N. These are adsorbed on the metal surface by these polar atoms, and protective films are formed, and various adsorption isotherms are obeyed. Various types of green inhibitors and their effect on different metals are mentioned in the paper.

Abstract The effect of organic inhibitors on corrosion fatigue performance of steel in a mixture of brine containing H2S-CO2 and diesel fuel is reported. The inhibitor concentration required to give significant protection to steel under corrosion fatigue conditions is much higher than that for corrosion control. This is due to the fact that corrosion fatigue cracks initiated at incompletely protected spots on the material surface influence fatigue failure regardless of the degree of protection achieved on neighboring areas. Effects of fatigue stress and concentration of corrosion inhibitors were investigated. Results were analyzed in terms of the proposed mechanism for corrosion inhibition in these environments.
