Abstract

L'invention concerne les techniques utilisant l'effet de détonation dans les gaz. L'installation faisant l'objet de l'invention est caractérisée en ce que dans la trémie est placée une cloison en matière perméable aux gaz, équidistante de ses parois et formant avec celles-ci une enceinte annulaire communiquant avec une source de gaz comprimé, et que dans le canal 11 reliant la chambre de mélange du doseur de poudre de matière de revêtement à la trémie 10, est monté un clapet anti-retour 26, 27, 28 fermant le canal 11 lors du choc en retour en provenance de la chambre d'explosion. L'invention peut être utilisée notamment pour l'application de revêtements en poudres à dispersion fine de matieres telles que les carbures de tungstène, de chrome et de molybdène.
