Figure 6: SEM images from the surface of samples produced with a bath load of 100 g/l, a current densities of 37 A/dm2 and different brushes:
From: Structure zone diagram and particle incorporation of nickel brush plated composite coatings

(a) grey Scotch-BriteTM, (b) polyester, and (c) white Scotch-BriteTM. The main image is taken with secondary electrons and the inserts are BS images of cross-sections, enabling visualization of aluminium particles (black dots). (d) and (e) are a higher magnification, back-scattered images of (b) and (c) respectively, false-coloured to show Al particles in blue and the Ni matrix in green.
