Abstract

1,271,303. Electrolytic colouring of anodized aluminium. ALCAN RESEARCH & DEVELOPMENT Ltd. June 6, 1969 [July 2, 1968], No.28900/69. Heading C7B. Anodized aluminium is coloured in a metal (e.g. Ni or Cu) salt bath by passing A.C. between the anodized aluminium work load 20, e.g. supported by bus-bar 24, and a counter-electrode structure 26, 27 arranged parallel to the work load, regularly spaced areas within the plane of the structure being unoccupied by effective currentemitting areas, the total effective area being at least 3% (e.g. up to 50%) of the planar area of the structure in relation to the adjacent work load. The structure may be composed of a grid or screen, or of an array of parallel vertical elements, e.g. rods, tubes or strips 28 carried by bus-bars 30, 31. The work load may be anodized aluminium sheet (as shown arranged between parallel counterelectrode structures 26 and 27), rods, bars or individual articles on a rack. The bath tank 22 may be lined with rubber or PVC. An aqueous acid Ni colouring bath is specified containing 25 g/1 Ni SO 4 . ZH 2 O, 20 g/l Mg SO 4 . ZH 2 O, 25 g/l H 3 BO 3 and 15 g/l (NH 4 ) 2 SO 4 with Ni counter-electrodes, the current density being 2À5-3À5 A.S.F. An aqueous acid 35 g/1 Cu SO 4 . 5H 2 O bath may be used with Cu counter-electrodes, the current density being 5 A.S.F., the counterelectrodes may be of graphite, and Ag salts or alkali metal tellurites or selenites may be used for colouring. The anodizing may be conducted in 15% H 2 SO 4 solution using D.C.
