Method For Two Step Electrolytic Coloring Of Anodized Aluminum

US Patent:
4931151, Jun 5, 1990
Filed:
Apr 11, 1989
Appl. No.:
7/336114
Inventors:
Kollengode V. Srinivasan - Marietta GA
Leo P. Herrington - Walker MI
Mores A. Basaly - Marietta GA
Harold W. Poulsen - Fort Wayne IN
Assignee:
Novamax Technologies Holdings Inc. - Ontario
International Classification:
C25D 1122
US Classification:
204376
Abstract:
A two-step process and apparatus for the electrolytic coloring of anodized aluminum using an electrode and the anodized aluminum immersed in an electrolyte. First the aluminum is anodized to form an oxidized film on its surface and then a coloring step is performed. In the coloring step a modified sinusoidal voltage waveform is applied to the anodized aluminum and the electrode to color the oxidized film. Suitably gated thyristors in the secondary of a power supply may be used to provide the desired voltage waveform. The voltage waveform is generated with a leading edge rise time in the negative portion substantially longer than in the positive portion. The average negative voltage is greater than the average positive voltage to provide good throwing power, coloring speed, color uniformity and electrode dissolution, with tha capability to subtract color. Excellent throwing power with fair coloring speed is obtained if the average negative voltage substantially equals the average positive voltage.
