Corrosion inhibitors function through various mechanisms:
Adsorption: Organic inhibitors often work by adsorbing onto the metal surface, forming a thin protective film that blocks corrosive substances. Film formation: Some inhibitors react with the metal surface to form a stable, insoluble film that acts as a barrier to corrosive agents. Passivation: Anodic inhibitors promote the formation of a passive oxide layer on the metal surface, which protects it from further corrosion. Scavenging: Some inhibitors work by scavenging oxygen or other corrosive species, thereby reducing their availability for the corrosion process.
