Abstract

L'invention concerne une méthode et un dispositif de projection gazodynamique de matériaux en poudre en vue de l'utilisation dans la mécanique et d'autres domaines industriels pour former des revêtements fonctionnels apportant des propriétés différentes sur les surfaces traitées. The invention relates to a method and a gas dynamic spraying device of powder materials for use in the mechanical and other industrial fields for forming functional coatings providing different properties on the treated surfaces. L'élargissement des capacités fonctionnelles et technologiques de la méthode et de l'appareil est atteint grâce au fait que des matériaux (métalliques ou non), en poudre de propriétés différentes sont alimentés simultanément dans les parties subsonique et/ou supersonique de la buse via les différents points d'alimentation afin d'assurer les conditions de projection optimales pour chaque matériau en poudre. Enlargement functional and technological capabilities of the method and apparatus is achieved by the fact that the materials (metal or otherwise), powder of different properties are fed simultaneously in the subsonic parts and / or supersonic nozzle via the different feed points in order to ensure the optimum spraying conditions for each powder material. Les poudres différentes sont injectées dans la buse supersonique via le point principal d'aümentation en poudre réalisé de sorte de permettre d'alimenter séparément les poudres différentes dans les parties subsonique et/ou supersonique de la buse et via les points supplémentaires d'alimentation des poudres différentes dans la partie supersonique de la buse, ces points supplémentaires étant réalisés sous forme d'éléments interchangeables et montés consécutivement et coaxialement à la partie supersonique de la buse. The various powders are injected into the supersonic nozzle via the main point of powder aümentation realized so to allow to separately supply the different powders in the subsonic parts and / or supersonic nozzle and via supply additional points different powders in the supersonic part of the nozzle, these additional points being in the form of interchangeable elements and consecutively mounted and coaxially with the supersonic portion of the nozzle.
