Beschreibung
Zusammenfassung:	Apparatus and process for solid-state deposition and consolidation of powder particles entrained in a subsonic or sonic gas jet onto the surface of an object. Under high velocity impact and thermal plastic deformation, the powder particles adhesively bond to the substrate and cohesively bond together to form consolidated materials with metallurgical bonds. L'invention concerne un appareil et un procédé pour déposer à l'état solide et consolider des particules de poudre entraînées dans un jet de gaz sonique ou subsonique sur la surface d'un objet. Sous l'effet de l'impact à haute vitesse et de la déformation plastique thermique, les particules de poudre se collent au substrat et s'assemblent de manière adhésive pour former des matériaux consolidés avec des liaisons métallurgiques.
