Andreev and Vesely, in dialogue with ChatGPT, propose a refined definition of "corrosion inhibitor" that covers the protection after-effect of pretreatment and separates inhibition from conversion treatment and bulk-phase coatings
In a question-and-answer dialogue with ChatGPT, the authors compare normative definitions from GOST 9.106–2021, NACE/ASTM G193-22 and ISO 8044:2024, point to the ISO requirement that an inhibitor be "present in the corrosion system" and to the absence of a distinction between the bulk environment and the near-surface region, and then define an inhibitor through its action on the metal or the corrosion system, offering working definitions of a chemisorbed layer, a conversion coating and a bulk-phase anticorrosion coating, and arriving at a refined definition that excludes substances whose action significantly changes the concentration of corrosive components in the bulk environment, forms a conversion coating, or involves applying a bulk-phase anticorrosion coating.
