Abstract
A process for depositing a compact film of particles on an internal surface of a part, including: a) placing the part in a carrier liquid; b) generating a carrier liquid stream in a hollow of the part towards a surface of the carrier liquid, to create a protuberance; c) dispensing the particles to form a compact film floating on the liquid between a contact line and an upstream front of particles; and d) transferring the film onto the internal surface by operating a relative displacement between the part and the surface of the carrier liquid, while continuing dispensing the particles on the upstream front.
