    Abstract: A powder feed splitter and a machine using a powder feed splitter, to divide a powder flow into two or more streams in a predictable, adjustable, and reliable manner for use in material processing such as welding. A housing encloses an inlet disk having an inlet regulator preferably a disk, having an inlet tube which may be adjustable radially or laterally with respect to the housing. An adjustment mechanism can selectively move the inlet regulator to adjust the powder flow amongst the several powder outlet ports. Funnel-shaped cavities within the housing may have optional gas inlets to enable the introduction of additional gas to the separated powder flow streams. A one-way fit may be present between the interior powder flow splitter and the exterior casing. Smooth interior surfaces through the device prevent turbulence and buildup of powder.

    Abstract: A laser plasma spray apparatus for depositing a feed material onto a substrate includes a nozzle having a plasma confinement chamber into which a laser beam is focused, the focal point being at a distance sufficiently far from the substrate that the substrate is not melted. Finely divided feed material in a carrier gas flow is fed axially into the confinement chamber along the direction of the laser beam and melted in the plasma formed in the interaction of the laser beam, the feed material, and the gas at the focal point. The melted feed material is then directed to deposit onto the substrate, while the plasma energy is largely confined within the apparatus by the confinement chamber and a constriction in the flow path upstream of the confinement chamber.

    Abstract: A feed material is melted by a focussed laser beam in a partially confined interaction volume, and ejected from the interaction volume in a direction different from the axis of the laser beam. The feed material, preferably in the form of a finely divided powder fluidized by a gas stream, is fed to the interaction volume in a direction transverse to the axis of the laser beam. Confinement of the molten feed material is preferably attained using balanced gas pressures that do not permit the molten feed material to flow in the direction parallel to the laser beam. The energy density of the laser beam is preferably sufficiently high to form a plasma within the interaction volume from gas and vaporized feed material atoms, so that the feed material is introduced into the plasma.
