【発明の名称】スーパーアロイに用いるアルミニウム処理コーティング
Document Type and Number:
Japanese Patent JP3001161
Kind Code:
B2
Abstract:
A protective coating system for superalloys is described. The coating is an active element enriched aluminide, and can be formed by aluminizing an overlay coated superalloy, wherein during the aluminizing process, aluminum diffuses completely through the overlay coating and into the substrate. The coating system exhibits desirable oxidation resistance and resistance to thermal fatigue cracking, due to the presence of oxygen active elements in the overlay.
