Development process for ecofriendly corrosion inhibitors

The metallic materials are main used materials, because, their physical properties, such as electrical conduction, thermal conduction, and mechanical performances. The steel based metallic materials are most common in the gas and oil industry [1–3]. However, a high percentage of the steel materials are damaged by corrosion in acidic environments [4]. Therefore, to protect steel materials is ongoing problem. Currently, many researches are interested to going research in the corrosion protection.
