摘要：

The outstanding corrosion resistance of stainless-steel is from its passive oxide. Environmental transmission electron microscope was used in a modern atomic-scale in situ initial oxidation analysis process to reveal the microstructural and elemental variation on its breakdown. An amorphous oxide layer was the main oxide when temperatures is lower than 500 degrees C, and pits formed from 500 degrees C, and a porous structure formed from 700 degrees C. The protective passive films on the oxide/alloy interface were damaged by priority structural oxidation and prompted further alloy failure. The study provides direct experimental data beyond that of traditional research.
