Abstract Electrochemical measurements and substrate analysis have been employed to study the corrosion of iron in sweet solution (pH = 6.8, T = 80 °C) over a period of 288 h. Correlated with decreasing corrosion rate, diffraction, microscopy, and spectroscopy data reveal the evolution of adhered sweet corrosion scale. Initially, it is comprised of two phases, siderite and chukanovite, with the latter affording little substrate protection. Subsequently, as the scale becomes highly protective, siderite is the sole component. Notably, siderite crystals are concluded to display a somewhat unexpected habit, which may be a trigger for local breakdown of protective sweet scales.

甜油田腐蚀规模的时间演变：阶段、形态、习性和保护

摘要 电化学测量和底物分析已被用于研究铁在 288 小时内在甜溶液（pH = 6.8，T = 80 °C）中的腐蚀。与腐蚀速率降低相关，衍射、显微镜和光谱数据揭示了粘附的甜腐蚀垢的演变。最初，它由两相组成，菱铁矿和 chukanovite，后者几乎不提供基材保护。随后，随着鳞片变得具有高度保护性，菱铁矿成为唯一的成分。值得注意的是，菱铁矿晶体被认为显示出一种有点出乎意料的习性，这可能是保护性甜鳞片局部分解的触发因素。
