Abstract

L'invention concerne des procédés de revêtement de matières internes consistant à produire des matières cibles et internes, à effectuer une ablation des matières cibles pour constituer des matières cibles particulaires ablatées, et à recouvrir les matières internes desdites matières cibles particulaires ablatées, ledit procédé étant réalisé à une pression d'au moins environ 10 Torr. Cette invention a également trait à des procédés permettant de recouvrir des particules de revêtements d'épaisseurs d'un à plusieurs manomètres à pression atmosphérique, et d'avoir recours à la fluidisation pneumatique.
