Abstract: A method includes introducing metallic powder into a fluidizing chamber of a fluidized bed reactor. A fluidization gas is flowed into the fluidizing chamber. The metallic power becomes entrained in the flow of the fluidization gas. Adsorbed water is removed from the metallic powder by exposing the metallic powder to the fluidization gas for a duration of time and at a treatment temperature to cause the adsorbed water to be removed from the metallic powder.

Abstract: A method for heat treating metal alloy powder includes (a) introducing metal alloy powder to a chamber having a floor and a sidewall; (b) flowing a fluidizing gas through the floor and into the chamber to fluidize the metal alloy powder in the chamber; (c) flowing an additional gas through the sidewall into the chamber; and (d) heating the chamber to heat treat the metal alloy powder in the chamber. A system for heat treating metal alloy powder includes an inner chamber having a porous floor and a porous sidewall; an outer chamber, the inner chamber being inside of the outer chamber and defining an annular space between the outer chamber and the inner chamber, wherein the outer chamber and the inner chamber are inside a furnace; a source of fluidizing gas connected to the porous floor through the annular space; and a source of additional gas communicated with the porous sidewall through the annular space.

Abstract: A cold spray system includes a powder generator and a powder feeder. The powder generator has a powder source disposed within a housing. The powder feeder is in fluid communication with the housing and the powder generator within the housing. A closed circuit defined from the powder generator to the powder feeder conveys powder from the powder generator to the powder feeder without exposing the powder to contaminates from outside the closed circuit.
