Abstract: A method of forming a conversion layer on a metallic surface and a composition usable in the method are provided. The composition is an aqueous solution comprising a source of tungstate ions and a soluble material comprising zirconium. The method provides a conversion coating on a surface that can then be painted or otherwise treated. The conversion coatings of the present invention are minimally affected by heating and/or baking, unlike chromate conversion coatings of the prior art.

Abstract: An aqueous conversion coating composition for treating metal substrates such as aluminum, aluminum alloys, zinc, zinc alloys, magnesium, magnesium alloys and steel to provide a conversion coating thereon. The conversion coating composition comprises a) a source of aluminum ions; b) a fluoro compound; c) at least one pH adjuster; d) a source of Group VIB metal ions selected from the group consisting of tungstate ions and trivalent chromium ions; and e) optionally, a preservative. The conversion coating composition provides a corrosion resistant coating on the metal surface and improves the adhesion of subsequently applied layers.
