さびでさびから鋼を守る : さび形成反応のメカニズム解明とその制御 Protecting Steel from Rusting by Rust : the Mechanism of Rust Formation and its Control
Weathering steel, when exposed outdoors for a few years, forms a protective layer resulting in reduction of the corrosion rate. The state of rusts is fundamental for understanding its mechanism, but the structure and its relationship with the mechanism have not been understood. In this study, a new crystallographic approach was applied to reveal nano-structure of rusts with using of X-ray synchrotron radiation. It has been shown that additional elements alter the corrosion process in its early stage, resulting in formation of protective rusts.
