Abstract Variously coloured coatings on aluminium were obtained by varying the duration of the a.c. electrolysis in a bath containing H3BO3, Ni(CH3COO)2 and (HOCH2 CH2)2 NH, after an initial d.c. pretreatment in a mixture of H3PO4 and H2SO4. Electron-optical observation of the micro structure reveals that many tiny columns grow on the outer layer of the anodic film and the column consists of fine nickel particles, together with amorphous material.
