摘要： A method for forming an oxide-dispersion strengthened coating on a metal substrate 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 μm. Additionally, the method includes applying the oxygen-enriched powder to the metal substrate to form a coating and heating the oxygen-enriched powder to precipitate oxide dispersoids within the coating.
