Abstract
Titanium nanocomposite (TiTR) was synthesised from Triumfetta rhomboidea leaf extract and used as corrosion protection of mild steel (MS) in 1 M hydrochloric acid. The corrosion inhibition process of the nanocomposite was explored using weight loss, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarisation (PDP). The corrosion inhibition performance of TiTR is a function of concentration and temperature. The results revealed that TiTR was 84.27% efficient in limiting MS corrosion at 1.0 g L−1 and 3 h. The TiTR acted as a mixed-type corrosion inhibitor and Langmuir isotherm indicated that TiTR was adsorbed on mild steel through physisorption by forming a monolayer of film. Surface morphology study of MS visually confirmed the protection of MS by TiTR through film formation.
以三棱叶提取物为原料合成钛纳米复合材料(TiTR)，并将其用于低碳钢(MS)在1 M盐酸中的防腐。利用失重、电化学阻抗谱(EIS)和动电位极化(PDP)对纳米复合材料的缓蚀过程进行了研究。tir的缓蚀性能是浓度和温度的函数。结果表明，在1.0 g L−1和3 h时，TiTR对MS腐蚀的限制效率为84.27%。Langmuir等温线表明，TiTR作为混合型缓蚀剂通过物理吸附在低碳钢上形成单层膜。质谱的表面形貌研究直观地证实了TiTR通过成膜对质谱的保护作用。
