Abstract: A powder feeder for a cold spray system includes a rotatable drum body, a housing surrounding the drum body, and a support structure. The support structure couples to the housing and supports the housing such that the drum body rotates about a rotation axis to provide in-situ blending of powder disposed within an interior of the drum body.
