Surface passivation
Definition
The act of passivating or chemically treating metal surfaces and its result; a technological process of thermochemical or electrochemical surface treatment of a metal or alloy to form a highly resistant protective layer. This structural phenomenon blocks material degradation through corrosion, frictional wear, or high-temperature oxidation, significantly extending the service life of parts in aggressive industrial environments.
