我们提出了铁膜在盐水溶液（0.1氯化钠）中的腐蚀作为测量液体TEM。通过成像捕获铁膜的溶解和腐蚀产物的成核。结果表明，形核起始于金属表面，沿沿着金属晶界择优生长。腐蚀产物的形成特点是在现场作为赤铁矿的电子衍射。通过原位TEM研究铁在溶液中的腐蚀及其产物的特性
We present the corrosion of an iron film in brine solution (0.1 NaCl) as measured by liquid TEM. Dissolution of the iron film and nucleation of the corrosion products is captured by imaging. It shows that nucleation initiates at the metal surface, with preferential growth along the metal grain boundaries. The corrosion product that forms is characterised in-situ as hematite by electron diffraction.
