Food flavors of 2-isobutylthiazole (ITT) and 1-(1,3-Thiazol-2-yl)ethanone (TEO) for the corrosion inhibition of X65 steel in H₂SO₄ were studied by electrochemical methods, atomic force microscopy (AFM), scanning electron microscopy (SEM) and theoretical calculations. Electrochemical experiments show that ITT and TEO can effectively inhibit the corrosion of cathode and anode of X65 steel, and they are mixed-type corrosion inhibitors. Surface topography analysis (SEM and AFM) also visually demonstrate that ITT and TEO form an effective barrier film on the X65 steel surface to isolate the corrosive medium. Theoretical calculations profoundly explain the inhibition mechanism of ITT and TEO at the molecular level. In addition, the adsorption behavior of ITT and TEO on the surface of X65 steel is consistent with Langmuir isotherm adsorption. The results of experimental and theoretical studies have shown that the inhibition effect of TEO is better than ITT for X65 in 0.5 M H₂SO₄.

2-异丁基噻唑（ITT）和1-（1,3-噻唑-2-基）乙酮（TEO）的食用香料，用于抑制X65钢在H ₂ SO _4中的腐蚀通过电化学方法，原子力显微镜（AFM），扫描电子显微镜（SEM）和理论计算进行了研究。电化学实验表明，ITT和TEO可以有效抑制X65钢的阴极和阳极腐蚀，它们是混合型腐蚀抑制剂。表面形貌分析（SEM和AFM）还从视觉上证明了ITT和TEO在X65钢表面上形成有效的隔离膜以隔离腐蚀性介质。理论计算深刻地解释了ITT和TEO在分子水平上的抑制机理。另外，ITT和TEO在X65钢表面的吸附行为与Langmuir等温线吸附一致。实验和理论研究结果表明，在0.5 MH下，TEO对X65的抑制作用优于ITT。₂ SO ₄。
