The disclosed process enables to repeat in an industrial and controllable way the electrolytic coloration of anodized aluminium, by differentiated and independent control of the colorimetric coordinates of the colour, i.e. the saturation, tonality and luminosity. The saturation control is obtained by carrying out the anodizing of aluminium to the prior anodized aluminium, whereby a mass-gel of alumina with high mobility is obtained. Said mass-gel is subjected to a current which causes the formation of micropores in the base of which is formed a mass-gel having a spherical shape and actuating as microlenses. The final colour control is performed by applying a pulsed direct current, the application time being the factor which will mark the colour on the obtained visible spectrum. The control of luminosity is obtained by electrodeposition of metal particles. |
