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：
CORROSION is the premier research journal featuring peer-reviewed technical articles from the world’s top researchers and provides a permanent record of progress in the science and technology of corrosion prevention and control. The scope of the journal includes the latest developments in areas of corrosion metallurgy, mechanisms, predictors, cracking (sulfide stress, stress corrosion, hydrogen-induced), passivation, and CO2 corrosion.
70+ years and over 7,100 peer-reviewed articles with advances in corrosion science and engineering have been published in CORROSION. The journal publishes seven article types – original articles, invited critical reviews, technical notes, corrosion communications fast-tracked for rapid publication, special research topic issues, research letters of yearly annual conference student poster sessions, and scientific investigations of field corrosion processes. CORROSION, the Journal of Science and Engineering, serves as an important communication platform for academics, researchers, technical libraries, and universities.
Articles considered for CORROSION should have significant permanent value and should accomplish at least one of the following objectives:
• Contribute awareness of corrosion phenomena,
• Advance understanding of fundamental process, and/or
• Further the knowledge of techniques and practices used to reduce corrosion.
