Abstract
The potential toxicity and environmental persistence of inorganic corrosion inhibitors have led researchers to pursue eco-friendly alternatives provide effective corrosion protection while reducing risks to human life and the environment. Corrosion is an electrochemical phenomenon that effect metallic structures worldwide resulting in crucial economic losses and environmental concerns. Traditional inorganic corrosion inhibitors ,including chromates, phosphates, and other heteroatoms –containing compounds ,have demonstrated excellent corrosion protection; nevertheless their toxicity and adverse environmental impacts have raised serious concerns regarding their widespread use, consequently , increasing attention has been directed toward the development of sustainable ,non-toxic, alternatives .Among these ,green corrosion inhibitors (GCIs) have emerged as promising candidates owing to their biodegradability, low toxicity, renewability, and high inhibition performance. This review provides mainly a comprehensive overview of recent studies on the application of (GCIs) for mild steel. It presents a concise discussion of the types of corrosion affecting mild steel , factors influencing the corrosion process and conventional corrosion prevention methods , including organic corrosion inhibitors .Furthermore , the review examines the classification ,inhibition mechanisms and practical application of green (GCIs) as well as specimen(plant extract) preparation procedures commonly employed in corrosion studies ,in addition a simplified overview of the principle electrochemical techniques and surface analysis used for corrosion evaluation is provided to facilitate a fundamental understanding of their role in corrosion investigations . finally , the review summarizes the most recent researches published over the past two years in a comprehensive table ,highlighting the types of green corrosion inhibitors investigated , experimental conditions , inhibition efficiencies and key findings.
Keywords: green corrosion inhibitors ,mild steel ,plant extracts
