  • METHOD AND SYSTEM FOR COLD DEPOSITION OF POWDERED MATERIALS ON A SUBSTRATE
    Publication number: 20240352590
    Abstract: A method and a system for cold spray deposition of a solid material on a substrate, the system comprising a fluid jet unit; a heating unit; a nozzle, and a powder feeder; the fluid jet unit providing a fluid of a speed up to 1200 m/s and a pressure in a range between 150 and 620 MPa to the heating unit, the heating unit controlling a temperature of the fluid and outputting one of: a superheated and a supercritical fluid; the powder feeder injecting feedstock powder particles into a mixing chamber of the nozzle, the feedstock powder particles being accelerated to a speed above a critical velocity of the feedstock powder particles by the fluid within the nozzle, the nozzle being configured for acceleration of the fluid, mixing the fluid and the feedstock powder particles, and projecting the mixture onto the substrate.

  • Method of on-line thickness measurement of applied coatings
    Patent number: 7758910
    Abstract: In a method of measuring the thickness of a coating as it is applied to a substrate, wherein the coating is applied as a thin ribbon from a spray gun, at least one surface profile of the applied coating is obtained along a line intersecting the ribbon during relative movement of the substrate and spray gun. The thickness of the applied coating is computed from the obtained surface profile.
