Abstract

Corrosion inhibition of mild steels is an importance topic since the use of mild steel is inevitable in chemical processing, petroleum production, refining, pipelines, mining etc. The low cost, high mechanical strength and availability are the main advantages of the use of mild steels. Corrosion of mild steels occurs when it exposes to aggressive environment. Numerous corrosion inhibitors are developed for the control of corrosion of metals and alloys. Compounds containing N, S and O are most studied due their higher inhibition ability. Particularly in recent years, heterocyclic compounds have attracted huge attention due its simple preparation and superior corrosion inhibition activity towards mild steel in acidic environments. Therefore, the aim of the present review is to highlight the recent work carried out using heterocyclic compounds and its derivatives for steel protection in different corrosive environments. In addition, heterocyclic compounds reported for the corrosion inhibition of steel in CO2 saturated brine environment are also highlighted. Detail mechanisms involved in the inhibition processes are also discussed.
