Figure 5: SEM images of samples produced with a bath load of 100 g/l, a brush of 3 M Scotch-BriteTM Red (7447) and current densities:
From: Structure zone diagram and particle incorporation of nickel brush plated composite coatings

(a) 75 A/dm2 and (b) 124 A/dm2. In both cases, the main image is taken from the surface with a secondary electron detector while the inserts are cross-sections taken with a back-scattered electron detector. (c) and (d) are high magnification BSE images of (b). The small black dots in (b) and the false-coloured blue particles (d) are aluminium.
