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 robotic deburring process that automatically, accurately, and efficiently removes burrs from a workpiece. The robotic deburring process uses CAM location data to establish deburring trajectory, physics based machining models to predict burr type and size, and force control functions to compensate inaccuracies due of inaccuracies of robots arms.

Abstract: A process of deburring a workpiece comprising installing a workpiece onto a machine table proximate a robot, the workpiece having a surface, the robot having at least one force sensor and a spindle load sensor associated with a spindle coupled to a cutting tool, the robot having at least one joint configured to be actuated by a joint actuator; the robot being coupled to a controller; generating joint encoder signals with the controller, the joint encoder signals configured to direct the joint actuator; sensing contact forces between the cutting tool of the robot and the surface of the workpiece; determining a deburring path of the cutting tool to deburr the workpiece; and controlling the robotic deburring process by use of the joint encoder signals, a physics based model of burr size and material removal, a nominal trajectory and an actual trajectory of the cutting tool center point position.

Abstract: A component may be self-monitoring having a sensor assembly located on a surface of a substrate and covered by an encapsulating layer additively manufactured over the sensor assembly and thereby bonded to the substrate. The sensor may be wireless, self-powered, and embedded into the substrate such that it is unobtrusive and may not limit the performance or function of the component.

Abstract: One embodiment includes a method for enhancing bond strength between a powder deposit and a substrate. Powder is deposited on the substrate. Powder is shot peened with peening media that is harder than both the powder and the substrate to produce bond strength between the powder and the substrate that is at least twice bond strength between the powder and the substrate without shot peening.

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.
