| 摘要 |
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.
