B, Areal fractal analysis confirms a clear difference in roughness between the surface with the drawing and other surfaces of L13.
Atomic Force Microscopy (AFM) showed an increase in roughness of the film.
But after 320 grit, gloss values increased greatly while change in roughness values was not significant.
Results showed a decrease both in roughness and water contact angle as pre-incubation time increases.
During the running-in of surfaces a change in roughness takes place.
Variation in roughness height along the considered bed feature is also discussed for a particular experiment.
Associated with this increase in roughness the surface energy increased from 36 to 61 mN/mm.
The substrates were chosen so that for each one, their two sides differ in roughness.
Depending on the coating manufacturing process, the MCrAlY surfaces may substantially differ in roughness.
