摘要： This invention relates to a method for the post-treatment of metal layers, especially for the post-treatment of metal layers deposited on the surface of a substrate. With the invention a method for the post-treatment of a metal surface is proposed, wherein the metal surface is brought into contact with a corrosion resistance increasing solution, characterised in that during the contacting of the metal surface with the corrosion resistance increasing solution a current is applied between the surface and a counter electrode, whereby the surface is anodic contacted and the counter electrode is cathodic contacted.

摘要： A process for treating the surface of a metal substrate comprising a constituent metal selected from the group consisting of Cr, Cu, Mn, Mo, Ag, Au, Pt, Pd, Rh, Pb, Sn, Ni, Zn, in some cases Fe, and alloys of these metals. An anodic potential is applied to the metal surface in an electrolytic circuit comprising the metal surface, a cathode, and an electrolytic solution that is in contact with the metal surface and in electrically conductive communication with the cathode. The electrolytic solution may contain an electrolyte comprising anions of phosphate, phosphonate, phosphite, phosphinate, nitrate, borate, silicate, molybdate, tungstate, carboxylate, oxalate and combinations thereof. The anion may comprise a polymer having a pendent moiety selected from the group consisting of phosphate, phosphonate, phosphite, phosphinate, sulfate, sulfonate, carboxylate and combinations thereof. The potential applied to the circuit is such that the substrate is anodically oxidized and reacts with the anion to form a composition that imparts an enhanced property to the metal surface. Preferably, the pH of the electrolytic solution is less than about 6.0, the potential applied is between about 0.5 and about 20 volts, and the current density is between about 0.01 and 2 amps/dm2 of the geometric surface area of metal in contact with the electrolytic solution and is controlled such that nascent cations of said constituent metal produced by anodic oxidation of said constituent metal react with said anions at the metal surface without significant formation of any oxide or hydroxide of said constituent metal.

摘要： The invention relates to an object with a coated surface, said coating is either made from a metal, or from a metal coating with a conversion layer, whereby the surface contains a visibly fluorescent or phosphorescent material. The coated surface can contain one or several of the following elements: nickel, zinc, chromium, gold, silver, ruthenium, palladium or copper. Said surface, however, can also contain brass, phosphate, nickel, copper or gold. The coated surface can contain a metal oxide. The metal can be aluminium, titanium or magnesium. In a method for the production of said object, the coating is applied by means of a galvanic or chemical method. The coating can also be applied by anodisation or by vacuum coating. The fluorescent or phosphorescent material is applied in the form of microcapsules in the solution, or is in the form of a pigment and applied as a suspension in the solution.
