| 摘要 |
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. |
