In this study, Dardagan Fruit (DF) from Bingӧl - Turkey was tested as inhibitor corrosion for mild steel protection in 1 M HCl solution using electrochemical techniques. The surface of mild steel was examined by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Elemental composition of the surface after exposing to test solutions was analyzed with the help of energy dispersive X-ray spectroscopy (EDX). Contact angle measurements were also performed to get information about the surface properties. Spectroscopic studies were performed to determine major components, chemical structure and adsorption mechanism of the extract. The excess surface charge of mild steel was determined using electrochemical impedance spectroscopy (EIS) and an inhibition mechanism was proposed. It was found that DF has good corrosion protection ability. The inhibition of corrosion rate reduces when concentration of DF and exposure time are increased and reaches 92% after 1 h and 97% after 6 h immersion to 3000 ppm inhibitor containing corrosive media. The high protection ability was assigned to formation of a homogenously distributed protective film over the metal.

在这项研究中，土耳其Bingӧl的Dardagan Fruit（DF）已通过电化学技术测试了在1 M HCl溶液中对缓和钢的保护作用，作为缓蚀剂的缓蚀剂。通过扫描电子显微镜（SEM）和原子力显微镜（AFM）检查低碳钢的表面。借助能量色散X射线光谱仪（EDX）分析了暴露于测试溶液后表面的元素组成。还进行接触角测量以获得有关表面性质的信息。进行了光谱研究以确定提取物的主要成分，化学结构和吸附机理。利用电化学阻抗谱（EIS）测定了低碳钢的过量表面电荷，并提出了抑制机理。发现DF具有良好的防腐蚀能力。当DF的浓度和暴露时间增加时，对腐蚀速率的抑制作用会降低，并在浸入3000 ppm含腐蚀剂的腐蚀剂中1小时后达到92％，6小时后达到97％。赋予高保护能力是为了在金属上形成均匀分布的保护膜。
