Atmospheric corrosion progression characterisation on metal substrates is a major problem in the field of corrosion science and Non-destructive Evaluation (NDE). A laser profilometry has been used to characterise the corrosion on the mild steel plate. Four mild steel (S275) samples have been exposed to marine environment (exposure time from 1 month to 10 months). Two features have been utilized to characterise thickness variation in the corrosion layer. These features have been used to characterise corrosion progression through experimental studies. The relationship between these features and corrosion progression has been derived which is useful for corrosion progression measurement, early stage corrosion prediction and monitoring areas.
