Figure 3: SEM images of samples produced with a current density of 37 A/dm2 and a brush of 3 M Scotch- BriteTM Red (7447).

(a) pure Ni coating, (b) Ni/Al coating (Bath load = 100 g/l). In both cases, the main image is taken from the surface with a secondary electron detector and the inserts are cross-sections taken with a back-scattered electron detector. The second insert in (b) is the superposition of a magnified back scattered image and EDS map, confirming dark particles shown in the cross-section inserts are Al.
