Passivation


Passivation is the process of making a material "passive" in relation to another material prior to using the materials together.

In the context of corrosion, passivation is the spontaneous formation of a hard non-reactive surface film that inhibits further corrosion. This layer is usually an oxide or nitride that is a few atoms thick.
