The condition of a metal surface that retards its normal reaction in a specified environment and is associated with the assumption of a potential more noble than normal. 3, record 1, English, - passivity
Record number: 1, Textual support number: 1 CONT
The passivity of metals and alloys is one of the most important phenomenon responsible for out metal-based civilization. Most structural metals are viable in an engineering sense only because of the existence of a surface oxide film whose thickness may be less than a few nanometers. Although the phenomenon of passivity has been known for more than 150 years, a satisfactory description of the passive state still eludes us. 4, record 1, English, - passivity

The term passivity is sometimes used for surfaces covered by very thin films of phosphate or chromate, such as are formed by immersion in solutions containing phosphoric acid and/or chromic acid. This usage is incorrect and is discouraged. 3, record 1, English, - passivity
