Filed:

Oct 3, 2000

Appl. No.:

09/678275

Inventors:

Steven G. Keener - Trabuco Canyon CA
Kevin T. Ruth - Trabuco Canyon CA

Assignee:

Boeing North American, Inc. - Seal Beach CA

International Classification:

B32B 1508

US Classification:

148529, 428220, 428328, 428332, 428421, 428457, 428461

Abstract:

A ferrous-alloy aircraft structural component such as a fastener is prepared by providing a ferrous-alloy component precursor that is not in its final heat-treated state, and coating with an aluminum-containing, curable organic coating material having a non-volatile portion that is predominantly organic and is curable at about the ferrous-alloy components tempering temperature. The coated, ferrous-alloy is then tempered to concurrently impart predetermined metallurgical properties to the finished, ferrous-alloy material, and cure the organic, aluminum-containing coating.
