| 摘要 |
A high-strength, corrosion- and heat-resistant aircraft structural component such as a fastener is prepared by providing a corrosion-resistant stainless steel or heat-resistant superalloy metallic component precursor that is not in its final heat-treated state, and coating with an aluminum-containing, curable polyaromatic phenolic coating material having a non-volatile portion that is predominantly organic and is curable at about the high-strength metallic alloy component's stress equalizing tempering temperature. The coated, high-strength metallic-alloy component is then thermally treated to concurrently impart pre-determined metallurgical properties to the finished, metallic substrate, and cure the organic, aluminum-containing coating.
