Pitting Corrosion Measurement Using 3D Profilometry

In this application note the Nanovea ST400 Profilometer is used to measure the surface of a corrosion pitted stainless steel coupon. The area measured was selected at random, and assumed large enough in that it could be extrapolated to make assumptions about a much larger surface. Density, area, volume, size and shape will be used here to quantify the level of corrosion.
