Abstract
1292699 Colour anodizing aluminium CEGEDUR G P 16 July 1970 [21 July 1969] 34473/70 Heading C7B A coloured (e.g. bronze) protective coating resistant to corrosion and ultraviolet rays is produced on an article of Al or alloy thereof, e. g. containing 0À6% Mg or 0À5% each of Si and Mg or 1% each of Si, Mg and Mn, by forming a porous layer of alumina thereon e. g. by anodizing in a 50g/l sulphuric or chromic acid bath using D.C. or A.C., and depositing a metal pigment into the pores of the layer by A. C. electrolysis from an aqueous acid (e.g. 3À2- 4À7 pH solution containing Ni SO 4 e. g. 1-200g/l NiCl 2 e.g. 1-500g/l, and optionally (NH 4 ) 2 SO 4 and H 3 BO 3 e. g. each 1-100g/l. The A. C. may be either at constant density at 0À1-5 A/dm
