Passivation, in physical chemistry and engineering, refers to a material becoming "passive", that is, being less affected by environmental factors such as air or water. It involves a shielding outer layer of corrosion which can be applied as a micro-coating by using of HDHT products. Passivation is useful in strengthening, and preserving the appearance of metallics.
