SEM micrographs showing (a) FMC00, (b) FMC10 and (c) FMC20 surfaces after exposure to potentiodynamic testing in HS and subsequent rinsing and sonication in ethanol. SEM micrographs for the same samples tested in HS + BSA are not shown due to the inability to remove the BSA residue prior to imaging.
