Powder mixtures containing uniform dispersions of ceramic particles in superalloy particles and related methods

摘要

Embodiments of a method (20) for producing powder mixtures (24) having uniform dispersions of ceramic particles (28) within larger superalloy particles (26) are provided, as are embodiments of superalloy powder mixtures. In one embodiment, the method includes producing (22) an initial powder mixture comprising ceramic particles mixed with superalloy mother particles having an average diameter larger than the average diameter of the ceramic particles. The initial powder mixture is formed (30) into a consumable solid body. At least a portion of the consumable solid body is gradually melted (32), while the consumable solid body is rotated at a rate of speed sufficient to cast-off a uniformly dispersed powder mixture (36) in which the ceramic particles are embedded within the superalloy mother particles.
