Abstract:
An article prepared by a method comprising the steps of:providing an article precursor stock made of an aluminum alloy, the article precursor stock being initially oversize as compared with the final required size of the article; solution treating and annealing the article precursor; deforming the article precursor; aging the article at room temperature; providing a curable, cross-linkable, phenolic resin-containing organic coating material in an organic solvent, the coating material having a non-volatile portion that is predominantly organic and is curable at about a heat-treatment temperature of the aluminum-alloy article precursor; applying the organic coating material to the aluminum-alloy article precursor; and heat-treating the coated aluminum article precursor to an ultimate shear strength of at least about 24,000 psi, at a temperature and for a time sufficient to cure simultaneously the organic coating.
