Passivation (chemistry)
In physical chemistry and engineering, passivation, refers to a material that becomes less affected by corrosion. Passivation involves making an outer layer out of a material that is less affected by corrosion. The material is put on as a microcoating. Passivation can only occur in certain conditions. It is used in microelectronics.[1]

Tempering colors are produced when steel is heated and a thin film of iron oxide forms on the surface. The color indicates the temperature the steel reached, which made this one of the earliest practical uses of thin-film interference.
The fitting on the left has not been passivated, the fitting on the right has been passivated.
