| Zusammenfassung: | A method (100) for forming an oxide-dispersion strengthened coating on a metal substrate (304) is disclosed. The method generally includes comminuting MCrAlY alloy particles to form an oxygen-enriched powder, wherein at least about 25% by volume of the MCrAlY alloy particles within the oxygen-enriched powder have a particle size of less than about 5 urn. Additionally, the method includes applying the oxygen-enriched powder to the metal substrate (304) to form a coating and heating the oxygen-enriched powder to precipitate oxide dispersoids within the coating. |
