The effects of cysteine (Cys) and l-methionine (l-Met) on copper corrosion inhibition were examined in 1 M HNO solution for short and long exposure times. Potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) were used. The EIS determined the potential for zero charges of copper (PZC) in the inhibitor solution. SEM and AFM have been used to study material surfaces. Energy-dispersive X-ray spectroscopy (EDS) was used to identify surface elemental composition. DFT and molecular dynamics simulations explored the interaction between protonated amino acids and aggressive media anions on a copper (111) surface.
在1 M硝酸溶液中，研究了半胱氨酸（Cys）和L-蛋氨酸（L-Met）在短时间和长时间暴露下对铜腐蚀抑制的影响。采用了动电位极化（PDP）和电化学阻抗谱（EIS）。EIS测定了抑制剂溶液中铜的零电荷电位（PZC）。利用扫描电子显微镜（SEM）和原子力显微镜（AFM）研究材料表面。采用能量色散X射线光谱（EDS）鉴定表面元素组成。密度泛函理论（DFT）和分子动力学模拟探索了质子化氨基酸与铜（111）表面侵蚀性介质阴离子之间的相互作用。
