Abstract
This study investigated the coupling effect of hydrogen and precipitates on the initiation of pitting using HR3C stainless steel with large NbCrN precipitates as the study material. Stainless steel exhibited good resistance to pitting when not subject to hydrogen charging. Hydrogen charging significantly reduced the corrosion resistance and stability of the passive film. Results obtained using the hydrogen microprint technique revealed that hydrogen was enriched within NbCrN precipitates and along the precipitate–substrate interface. Through immersion experiments, we discovered that pits preferentially initiated at the precipitate–substrate interface because it had weaker corrosion resistance than the precipitates.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
