Abstract

Hydrogen embrittlement (HE) threatens the structural integrity of industrial components exposed to hydrogen-rich environments. This review critically explores hydrogen barrier coatings (HBCs), polymeric, metallic, ceramic, and composite, their application and assessment, focusing on measured effecti...
