Corrosion Behavior and Resistance of Stainless and High-Entropy Alloys
This community investigates how metallic alloys, particularly stainless steels and high-entropy alloys, degrade in aggressive chemical environments and how their surface properties can be modified to prevent failure.
The work centers on the electrochemical mechanisms of pitting, crevice, and stress corrosion cracking in chloride-rich solutions. Researchers analyze the formation and breakdown of passive oxide films on austenitic, duplex, and martensitic stainless grades, as well as newer multi-principal element alloys. Key methodologies include impedance analysis, surface hardening treatments like plasma nitriding, and the study of microbiologically influenced corrosion. The investigation extends to high-temperature water environments and the mechanical degradation of aluminum and titanium alloys under corrosive stress.
Chromium research accounts for the largest share of this community's output at 2.1%, followed by Nickel at 1.2% and Chlorine at 1.3%. The community comprises 25,118 papers, published primarily in Corrosion Science, Corrosion, and the Journal of The Electrochemical Society.
Recent work continues to focus on mechanistic insights into passive film stability in supercritical water, the corrosion behavior of additively manufactured high-entropy alloys, and the interaction between mechanical stress and passivation in titanium and aluminum systems.
