Abstract

Differences in hydrogen entry behaviour for bare steel, zinc-coated steel with artificial defects in the coating, and steel with intact zinc coating were studied using scanning Kelvin probe technique. Pit formation was a key factor in the hydrogen entry mechanism for bare steel specimens. The steel/zinc interface covered with zinc corrosion products is the principal area of hydrogen entry into sheets with artificial defects in zinc coating. Hydrogen uptake was also observed in intact zinc-coated steel. The presence of a long line defect in the zinc coating led to almost eight times higher hydrogen uptake compared to bare steel.

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.
