Mild steel provides strength to various building and industrial materials but it is badly affected by corrosion. In the present study, we investigate the efficacy of , a plant-based green corrosion inhibitor to minimize mild steel corrosion in a 1 M HSO solution. Weight loss, surface coverage, inhibition efficiency, and corrosion rate measurements were evaluated for various inhibitor concentrations and time intervals. was found to be 98.35% efficient in preventing mild steel from acid corrosion by forming a barrier that reduces the interaction between mild steel and the acidic environment, it was further validated by UV-Vis and contact angle investigations. The scanning electron microscopy images demonstrated the inhibitor's protective effect, showing a smoother surface. These investigations show that the inhibitor significantly improves mild steel's corrosion resistance, offering immediate and long-term protection in acidic environments, even at deficient concentrations. It shows promise as an effective natural inhibitor and merits further consideration for future applications.
低碳钢为各种建筑和工业材料提供强度，但它极易受到腐蚀的影响。在本研究中，我们研究了一种植物基绿色缓蚀剂在1 M硫酸溶液中使低碳钢腐蚀最小化的效果。针对不同的缓蚀剂浓度和时间间隔，评估了失重、表面覆盖率、缓蚀效率和腐蚀速率测量值。通过形成一道减少低碳钢与酸性环境之间相互作用的屏障，发现该缓蚀剂在防止低碳钢酸腐蚀方面的效率达98.35%，通过紫外-可见光谱和接触角研究进一步验证了这一点。扫描电子显微镜图像显示了缓蚀剂的保护作用，呈现出更光滑的表面。这些研究表明，该缓蚀剂显著提高了低碳钢的耐腐蚀性，即使在浓度不足的情况下，也能在酸性环境中提供即时和长期的保护。它有望成为一种有效的天然缓蚀剂，值得在未来应用中进一步考虑。
