<P>PROBLEM TO BE SOLVED: To provide a method for forming an oxide dispersion strengthened coating that provides erosion resistance without sacrificing environmental protectiveness. <P>SOLUTION: There is disclosed a method (100) for forming an oxide dispersion strengthened coating on a metal base material (304). The method generally includes a step of comminuting MCrAlY alloy particles to form an oxygen-enriched powder, wherein at least about 25% by volume of the MCrAlY alloy particles included in the oxygen-enriched powder have a particle size of less than about 5 μm. Further, the method includes a step of applying the oxygen-enriched powder to the metal base material (304) to form a coating, and a step of heating the oxygen-enriched powder to precipitate oxide dispersoids within the coating. <P>COPYRIGHT: (C)2013,JPO&INPIT |
