This abstract first appeared for US patent application 18973613 titled 'ALUMINUM-CHROMIUM OXIDE COATING AND METHOD THEREFOR
Original Abstract Submitted
A method applies one or more films of polynuclear aluminum oxide hydroxide and polynuclear chromium hydroxide to a metal substrate. A method thermally treats the metal substrate with the one or more films at a temperature of at least 250° C., the thermal treatment reducing the polynuclear aluminum oxide hydroxides and the polynuclear chromium hydroxides to at least one layer of aluminum-chromium oxide.
