Abstract
1486631 Colour-anodizing aluminium NIPPON LIGHT METAL CO Ltd and RIKEN LIGHT METAL INDUSTRY CO Ltd 19 Sept 1974 [21 Sept 1973] 40810/74 Heading C7B Al or an alloy thereof with or without an anodized oxide layer is coloured by electrolysis while connected as at least one electrode in a bath containing a colour-forming metal salt using a pulsating voltage of which the polarity is reversed at intervals longer than the single pulse period. The voltage may be half-wave rectified single-phase AC, optionally derived by phase control with an Si rectifier, or may be an essentially rectangular wave, e.g. derived from a commercial multi-phase AC. The positive and negative pulses may be symmetrical with a peak voltage Vp of 50-150V, a pulse duration of 2-500 mSec, a pulse period of 1-1000 mSec and a phase reversal frequency of 0À2-240 sec. Advantageously the decay time of charges stored in the cell from Vp to Vp is within 1/3h where h is the quiescent time between pulses, (h may be 18mSec) and this may be achieved by adding a parallel variable resistor in the circuit, e.g. from 10-500#. When multi-phase AC is used the pulse period may be based on the unit period of the AC. Treatment at 0À2-11 A/dm<SP>2</SP> is specified for 60 min to give a coating of 0À8-30Á thick. An acidic bath based on H 2 SO 4 , malonic, maleic, malic, oxalic, sulphosalicylic, sulphamic or tartaric acid is useful, containing such salts as Ag 2 SO 4 , AgNO 3 HAuCl 4 , Na 2 SeO 3 , CuSO 4 , SuSO 4 , NiSO 4 or CoSO 4 . Conventional cleaning treatments may be used, or the negative pulses may be used to achieve degreasing.
