Abstract

The crystal structure of the rust layer was visualized in the initial corrosion behavior of carbon steel using synchrotron radiation μ-XRD analysis. Analysis of the μ-XRD spectrum by neural networks showed that the rust layers had a multilayer structure of inner layer (α-FeOOH) and outer layer (α-FeOOH and γ-FeOOH) from 1 week exposure, and α-FeOOH single phases were observed at the corrosion progress point after 4 week exposure.
