[Analysis Case] Evaluation of SUS Passive Film Depth Direction State and Oxide Film Thickness

It is possible to capture molecular information of inorganic substances in the depth direction using TOF-SIMS.

Stainless steel (SUS) is excellent in corrosion resistance and is used in various industrial products and components. Although it is a material resistant to corrosion, changes in the composition of the surface passive film due to aging or processing can lead to issues. In this instance, we introduce a case study analyzing the state of the metal oxide film on the surface of stainless steel using TOF-SIMS. TOF-SIMS allows for the high-sensitivity acquisition of molecular information in the oxide state, enabling the distribution of oxides ranging from a few nanometers to several tens of nanometers on the surface to be obtained, and spatial distribution can be evaluated through image analysis. Measurement method: TOF-SIMS Product field: Manufacturing equipment and components Analysis purpose: Evaluation of chemical bonding state, composition distribution, and thickness of corrosion layers For more details, please download the materials or contact us.
