Title (EN) PROCESS FOR DEPOSITING A COMPACT FILM OF PARTICLES ON THE INTERNAL SURFACE OF A PART HAVING A HOLLOW DELIMITED BY THIS INTERNAL SURFACE
(FR) PROCEDE DE DEPOT D'UN FILM COMPACT DE PARTICULES SUR LA SURFACE INTERIEURE D'UNE PIECE PRESENTANT UN CREUX DELIMITE PAR CETTE SURFACE INTERIEURE
Abstract: front page image
(EN)The invention relates to a process for depositing a compact film of particles (4) on the internal surface (10) of a part (2), comprising the following steps: a) placing the part (2) in a carrier liquid (6); b) generating a flow of carrier liquid (44) into the hollow (8) of the part in the direction of the surface (18) of the carrier liquid, so as to create a protuberance (50); c) dispensing the particles (4) in order to form a compact film floating on the liquid (6) between a contact line (20) and an upstream front (6) of particles; and d) transferring the film (4) onto the internal surface (10) by performing a relative displacement between this part (2) and the surface (18) of the carrier liquid, while continuing to dispense particles (4) onto the upstream front (60).
(FR)L'invention concerne un procédé de dépôt d'un film compact de particules (4) sur la surface intérieure (10) d'une pièce (2), comprenant les étapes suivantes : a) placer la pièce (2) dans un liquide porteur (6); b) générer un flux de liquide porteur (44) dans le creux (8) de la pièce en direction de la surface (18) du liquide porteur, de manière à créer une protubérance (50); c) dispenser les particules (4) pour former un film compact flottant sur le liquide (6) entre une ligne de contact (20) et un front amont (60) de particules; et d) transférer du film (4) sur la surface intérieure (10) en opérant un déplacement relatif entre cette pièce (2) et la surface (18) du liquide porteur, tout en poursuivant la dispense des particules (4) sur le front amont (60).
