Title:
ARTICLE OF MANUFACTURE AND PROCESS FOR ANODICALLY COATING AN ALUMINUM SUBSTRATE WITH CERAMIC OXIDES PRIOR TO ORGANIC OR INORGANIC COATING
Document Type and Number:
WIPO Patent Application WO2006047500
Kind Code:
A9
Abstract:
An article of manufacture and a process for making the article by the anodization of aluminum and aluminum alloy workpieces to provide corrosion-, heat- and abrasion-resistant ceramic coatings comprising titanium and / or zirconium oxides, and the subsequent coating of the anodized workpiece with a second coating such as polytetrafluoroethylene ("PTFE") or silicone containing coatings. The invention is especially useful for forming longer life coatings on aluminum substrates by pre-coating the substrate with an anodized layer of titanium and/or zirconium oxide that provides excellent corrosion-, heat and abrasion-resistance in a hard yet flexible film.
