Passivaatiotason

Passivaatiotason refers to the level of passivation achieved by a material. Passivation is a process that forms a protective layer on the surface of a metal or alloy, making it less reactive and more resistant to corrosion. The passivity level indicates how effectively this protective layer is formed and maintained.

Different materials and different passivation treatments can result in varying passivity levels. A higher passivity level generally means greater resistance to chemical attack and a longer service life for the material. This is crucial in applications where materials are exposed to corrosive environments, such as in the chemical industry, medical devices, or aerospace components.

The passivity level can be assessed through various analytical techniques. These methods evaluate the composition and thickness of the passive film, as well as its integrity and ability to protect the underlying material. Factors influencing the passivity level include the material's composition, the passivation process parameters (like chemical concentrations, temperature, and time), and the service environment. Maintaining an adequate passivity level is essential for ensuring the performance and reliability of manufactured goods.
