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 component's 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.
