HIGH RESOLUTION TECHNIQUES
Many of our experimental investigations rely on state-of-the-art, high resolution
instrumentation for quantitative analysis of corrosion processes and for imaging reactive
materials in corrosion environments.
- Atomic Force Microscopy (AFM),
- Scanning Tunneling Microscopy (STM),
- Phase-Measurement Interferometric Microscopy (PMFM),
- Environmental Scanning Electron Microscopy (E-SEM),
- Scanning Electrochemical Microscopy (SECM),
- Confocal Laser Scanning Microscopy (CLSM), and
- Near Field Scanning Optical Microscopy (NSOM).
These instruments are able to image different aspects of samples in contact with a
gaseous or liquid
environment at sub-micron to angstrom resolutions. We are also developing new types of
microscopies:
- Photoelectrochemical Microscopy (PEM) measures electronic properties of ultra thin
oxide
films and
- Kelvin microprobe
adapted to measure local corrosion potentials with high spatial resolution.
- related to high temperature corrosion, the nano-indentor is a high resolution technique
measuring local
mechanical properties of oxide scales.
These specialized instruments provide a more detailed picture, and in some cases the first
atomic-level picture, of corrosion processes.
