Abstract | The present invention concerns membranes and a process of realizing membranes that comprises the following steps: - preparing a substrate by sintering of metal powders, ceramics or their composites, with dimensions between 1 and 50 microns; - covering said substrate by thermal deposition of a layer of the same or different ceramic material, metal or alloys and composites; - cooling said layer during and/or after its thermal deposition; and possibly - a further step of covering said layer realized by thermal deposition through physical vapor deposition (PVD) or chemical vapor deposition (CVD) of a layer of a same or different material.
L'invention porte sur des membranes et sur leur procédé de réalisation qui comporte les étapes suivantes: préparation d'un substrat par frittage de poudres métalliques et céramiques et de leurs composites, d'une taille comprise entre 1 et 50 microns; recouvrement dudit substrat par dépôt par pyrolyse d'une couche de matériau céramique, de métal ou d'alliages et de composites, identiques ou différents des précédents; refroidissement de ladite couche pendant et/ou après le dépôt par pyrolyse; et éventuellement recouvrement de ladite couche d'un revêtement par dépôt physique en phase vapeur (PVD) ou dépôt chimique en phase vapeur (CVD) d'un matériau identique ou différent des précédents. |
