corrosion inhibitor

[kə′rōzh·ən in‚hib·əd·ər]
(physical chemistry)
A compound or material deposited as a film on a metal surface that either provides physical protection against corrosive attack or reduces the open-circuit potential difference between local anodes and cathodes and increases the polarization of the former.

corrosion inhibitor

Any of a number of materials used to prevent the oxidation of metals; may be a coating applied to the surface, a paint undercoat, or an element alloyed with the metal.
