Corrosion Evaluation With 3D Metrology

Corrosion is responsible for millions of dollars in material loss every year. Iron, steel and many other metals corrode during oxidation slowly causing the breakdown of the material surface. Corrosion measurement is a quantitative method by which the rate of corrosion can be evaluated to provide control and prevention understanding. Interest in corrosion measurement covers a broad spectrum of technical approaches including acoustic, electrical & mechanical. Non-contact Profilometer is an alternative approach used to measure the corrosive rate and material loss by obtaining surface topography measurement at nanometer levels.
