passivation
"The formation of a thin adherent film or layer on the surface of a metal or mineral that acts as a protective coating to protect the underlying surface from further chemical reaction, such as corrosion, electrodissolution, or dissolution. The passive film is very often, though not always, an oxide. A passivated surface is often said to be in a ""passive state."" The surface oxidation can result from chemical or electrochemical (anodic) oxidation. During anodic passivation, in the current-potential plots, the current, instead of increasing with potential, falls to a very small value. See passivation potential. See also an Encyclopedia Article.

Passivation
Passivation is the process of making a material "passive" in relation to another material prior to using the materials together. For example, prior to storing hydrogen peroxide in an aluminium container, the container can be passivated by rinsing it with a dilute solution of nitric acid and peroxide alternating with deionized water. The nitric acid and peroxide oxidizes and dissolves any impurities on the inner surface of the container, and the deionized water rinses away the acid and oxidized impurities. Another typical passivation process of cleaning stainless steel tanks involves cleaning with NaOH and citric acid followed by nitric acid (up to 20
t 120F) and a complete water rinse. This process will restore the film, remove metal particles, dirt, and welding generated compounds (ex. oxides).
