As a result, researchers must devote practically all of their effort to reducing steel corrosion difficulties, which leads to economic loss control. Researchers are using a variety of techniques to prevent mild steel corrosion, including the development of high strength, low alloys, corrosion resistant steel, as well as various coatings and inhibitors. In this study, I used an eco-friendly corrosion inhibitor to examine the inhibitory capacity of allium cepa (onion peel) in different solvents against mild steel corrosion in 1.5 M NaCl. Most organic inhibitors are effective because they contain hetero atoms, such as O, S, and N, in their chemical formulas, which are adsorbed onto the steel surface and give corrosion protection in acid solutions, as well as stop the cathodic and anodic reactions at the steel/acid interface. They are, however, costly, dangerous, and necessitate the use of a synthesis expert. Green corrosion inhibitor, on the other hand, is costeffective, environmentally beneficial, and may be obtained from natural resources. Researchersmust devote more time and effort to developing and studying a green inhibitor for usage in NaCl solutions, which showed an inhibitory efficacy of more than 83 percent when using AEOP and roughly 90.142 percent when using an aqueous extract of onion peel. As a result, it is recommended that research be expanded and that a focus be placed on environmentally friendly corrosioninhibitors for a more sustainable society.

1. INTRODUCTION Because metal iron and alloys have good mechanical, thermal, and electrical qualities, which are vital parameters for the selection of any material for industrial and construction purposes, they play a critical role in the development of any nation's infrastructure. Due to their excellent performance cost ratio, steel-made objects are frequently utilized in numerous infrastructure and engineering projects [1]. Corrosion, on the other hand, is a prevalent concern with steel-made things. Corrosion has a significant impact on the appearance and functionality of items [2]. Corrosion is defined as a destructive chemical

might result in a part or framework's capacity being reduced. Because pure metals tend to revert to their previous state of oxides, sulphides, and other compounds, it is sometimes referred to as the reverse process of producing/ extracting metal for ores. Corrosion prevention and maintenance accounted for about 3.5 percent of global GDP. Much of the nation's wealth can be safeguarded and diverted to other sectors, such as high-tech infrastructure development, education, road safety, poverty reduction, and food security. Many industrial mishaps have occurred in the past as a result of corrosion, and many people have died as a result. People have utilized a variety of techniques to address these issues. Waste natural materials (WNM) are stated to be a good economic solution to steel corrosion concerns based on research [4-5]. In diverse media, these WNM create a barrier layer around steel and delay corrosion [6, 7]. The effectiveness of the barrier layer is determined by the molecules that form it. Various investigations claim that aromatic compounds, in combination with inhibitor heteroatoms, are highly efficient against corrosion [8, 9]. As a result, selecting inhibitors based on the features listed in the preceding line can be a first step before evaluating inhibitors for corrosion resistance.
1 Materials Selection: There are no metal which are harsh toward corrosion in all circumstances, yet through examining and understanding the environmental conditions that actuates corrosion, changes looking like the metal utilized can likewise prompt a generous decrease in the corrosion. The wellbeing information on metal corrosion can be utilizedas a component of a blend of regular conditions information to decide the appropriateness of each metal. In explicit cases, the progression of novel mixtures expected to secure against ccorrosion is as yet under gathering. Furthermore, surface examination additionally assumes a basic part for assurance against corrosion harmful metal.
