摘要： A spray nozzle has a body having a flow passage. At least along a portion of the flow passage the body has a depth-wise compositional variation having: a cemented carbide first region; and a cemented carbide second region closer to the flow passage than the first region and having a higher boron content than a boron content, if any, of the first region.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A fluidized powder heat treatment classification assembly includes a gas source. A fluidized bed is connected to the gas source via a metered connection. The fluidized bed includes a first output connected to a powder classifier via at least a first valve. The powder classifier includes a catch container operable to decelerate a gas flow from the output and operable to catch particles entrained in the gas flow.

摘要： 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.
