Abstract
Pitting of austenitic stainless steel (SS) is intensified under hydrogen environment, resulting in great uncertainty of safety. However, austenitic SS printed by selective laser melting (SLM) after electrochemical hydrogen-charging manifests an unanticipatedly anti-pitting behavior. Pitting resistance is found in all the SLM samples after H-charging, while the original SLM and all the commercial SS samples are composed of corrosive pits on the surfaces. XRD, EBSD and TEM observations of SLM sample after H-charging reveal that nanotwins and ɛ-phase are newly formed interior of the cellular cells, which inhibit martensite transformation and enhance the formation of Cr oxides in passivation film.
期刊介绍:
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
