Application of Fourier analysis to the study of roughness profiles of eroded samples
Keywords:Erosion-corrosion, Roughness, Fourier transform, Surface quality
Fourier transforms are applied to analyse surface roughness profiles recorded on samples coming from erosion-corrosion essays. The information retrieved using this method clearly complements that revealed by the more classical roughness amplitude parameters. The analysis procedure here proposed can be applied not only to characterise the surface of corroded samples but, in general, to evaluate the quality of any surface after application of finishing treatments.
