Abstract

The process for providing colored coatings on aluminum and alloys of aluminum in which the surface is first anodized to form a porous layer and colored particles of metal compound are deposited in the porous layer by alternating current electrolysis with the object mounted as an electrode in an electrolyte containing the salt of the metal, and then subjecting the deposited particles to dissolution by mounting the object as an anode for direct or rectified current electrolysis until a color of the desired value is secured.
