  • Publication number: 20200306886
    Abstract: An assembly for measuring metal powder material mass flow rate during direct metal deposition is disclosed. A detection strip is placed in the gas-blown metal powder material flow path. The detection strip is fixed in one end and suspended at the other end. The flowing metal powder material particles induce displacement to the detection strip. A displacement measurement sensor measures the amount of displacement of the detection strip. The amount of displacement of the detection strip gives relationship to the amount of the metal powder material flowing in the metal powder material flow path. Preferably, the detection strip and the sensor are enclosed in a housing with a metal powder material inlet port and metal powder material outlet port and includes internal features for smooth travel of metal powder material particles.

  • Patent number: 10160127
    Abstract: Direct metal deposition (DMD) is used to fabricate knife edges with extended service life. A metal alloy powder is deposited along a blank and melted with a laser beam so that the powder solidifies into a strip of material having a hardness and/or wear resistance greater than that of the starting material. The piece is then finished to produce a sharp edge in the solidified material. The powder may be melted while it is being deposited, or it may be melted after being deposited. A slot or groove may be formed in the blank with the metal alloy powder being deposited into the slot or groove. A hardened steel alloy powder is deposited onto a mild steel blank. For example, a tool steel or vanadium steel powder may be deposited onto a 1018 steel blank. An invention line-beam nozzle may be used for deposition and/or powder melting.

  • Publication number: 20160271732
    Abstract: A method of performing direct material deposition onto a metallic substrate uses a source of an energy beam. A nozzle is coordinated with the source of the energy beam for infusing material relative to the energy beam generated by the source. The energy beam creates a melt pool on the metallic substrate. The source of the energy beam and the nozzle move along a predetermined path to generate a material deposition bead upon the substrate. A pre-heater is provided that is cooperatively controlled with the source of the energy beam and the nozzle. The pre-heater is moved along the predetermined path preceding the energy beam for heating the metallic substrate prior to the energy beam generating the melt pool. The nozzle infuses the melt pool with material for creating a direct material deposition bead upon the metallic substrate.

  • Publication number: 20160083850
    Abstract: A method of enhancing wear resistance of a metallic substrate includes applying a coating of an interstitial element to a surface of a substrate. A laser beam is directed onto a localized area of the metallic substrate coated with the interstitial element locally raising a temperature of the metallic substrate to a temperature causing the interstitial element to diffuse into the substrate. A layer of alloy including the interstitial element is generated onto the localized area of the metallic substrate. A focal point of the laser beam is disposed at a location spaced from the surface of the substrate for optimizing a power density of the laser beam at the surface of the substrate. The coating of interstitial element not diffused into the substrate is removed exposing the layer of alloy including the interstitial element.
