Surface Metrology for Corrosion Analysis

Three-dimensional profile of a crevice corrosion site for characterizing penetration depth variation and measuring maximum penetration depth.
Surface metrology for corrosion analysis and interpretation is provided to a wide range of industrial and government clients by the Geosciences and Engineering Division of Southwest Research Institute (SwRI). Surface metrology is the measurement of small-scale features on surfaces. A state-of-the-art laser profilometer is part of our suite of instrumentation for critical materials examinations.
Laser Profilometry
Laser profilometry provides fast, accurate noncontact assessments of corrosion. Its detailed, multi-dimensional topographic profiles support analysis and interpretation of complex corrosion processes and related failures.
Advantages of laser profilometry include:
- Noncontact, fully automatic imaging
- 0.5 micron resolution
- 2-D and 3-D profiling of sample sizes up to 15 x 20 x 13 cm
