Abstract

La présente invention est un procédé de recouvrement d'un objet par un film provenant de la fusion d'une mince couche de poudre dans lequel (a) on dispose d'un lit de poudre fluidisée électrisée dans une cuve, cette poudre étant chargée par un dispositif tribochargeur à circulation forcée, (b) on trempe dans la cuve l'objet relié à un potentiel zéro ou suffisant pour le recouvrir de poudre, (c) on place ensuite l'objet recouvert de la poudre dans un four à une température suffisante jusqu'à obtenir le film de revêtement par fusion de la poudre. Selon une forme avantageuse de l'invention le four comprend des électrodes portées à un potentiel électrique élevé afin de provoquer un effet couronne qui compense la relaxation de la charge des particules de poudre pendant leur chauffage. On maintient ainsi la charge des particules et donc elles restent sur l'objet et peuvent ainsi former le film par fusion. La présente invention concerne aussi l'appareillage pour la mise en oeuvre du procédé.
