Abstract
Official abstract text for this publication.
A method is disclosed for treating an anodized metal surface. According to the method, polynuclear clusters comprising aluminum oxide hydroxide are applied to the anodized metal surface.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of surface treating a metal article, comprising: anodizing the metal article to form an anodized surface on the metal article; and applying polynuclear aluminum clusters comprising aluminum oxide hydroxide to the anodized surface, wherein the polynuclear aluminum oxide hydroxide clusters comprise Al 13 clusters according to the formula: [AlO 4 Al 12 (OH) 24 (H 2 O) 12 ] 7+ *[(7/n) X −n ] 7− where X −n represents ‘−n’ charge-bearing X counter-ion species and (7/n) X −n are needed to neutralize the total complex charge, or Al 30 clusters formed by condensation of two of said Al 13 clusters bridged with four monomeric aluminum ions. 2. The method of claim 1 , wherein applying the polynuclear aluminum oxide hydroxide clusters comprises: applying a coating composition comprising the polynuclear aluminum oxide hydroxide clusters to the anodized surface; optionally titrating the applied coating composition to an alkaline pH to gel the applied coating composition; drying the applied coating composition to remove water; and optionally subjecting the dried composition to heat treatment.
