摘要：
A method of providing a transparent layer of aluminum oxide or a layer stack of aluminum oxide and one or more other metal oxides on a substrate by providing the Al and optionally the other metals on the substrate and then oxidizing the assembly electrolytically is shown in which a conductive layer of tin oxide and indium oxide and/or cadmium oxide, if necessary doped to increase the conductivity, is provided between the Al and the substrate. As a result of this the Al is converted completely into oxide so that an optical transmission is obtained which is as high as possible.
