20.500.12556/RUL-135970 Investigating the feasibility of preparing metal-ceramic multi-layered composites using only the aerosol-deposition technique The preparation of metal–ceramic layered composites remains a challenge due to the incompatibilities of the materials at the high temperatures of the co-firing process. For densification, the ceramic thick-film materials must be subjected to high-temperature annealing (usually above 900 °C), which can increase the production costs and limit the use of substrate or co-sintering materials with a low oxidation resistance and a low melting point, such as metals. To overcome these problems, the feasibility of preparing dense, defect-free, metal–ceramic multilayers with a room-temperature-based method should be investigated. In this study, we have shown that the preparation of ceramic–metal Al$_2$O$_3$/Al/Al$_2$O$_3$/Gd multilayers using aerosol deposition (AD) is feasible and represents a simple, reliable and cost-effective approach to substrate functionalisation and protection. Scanning electron microscopy of the multilayers showed that all the layers have a dense, defect-free microstructure and good intra-layer connectivity. The top Al$_2$O$_3$ dielectric layer provides excellent electrical resistance (i.e., 7.7 × 10$^{12}$ Ω·m), which is required for reliable electric field applications. aerosol deposition multi-layered composites interdigitated aluminium electrodes alumina insulating layers aerosolno nanašanje večslojni kompoziti povezane aluminijeve elektrode aluminijevi izolirni sloji true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-05 10:15:55 2022-04-05 10:16:01 2022-09-15 04:13:01 0000-00-00 00:00:00 2021 0 0 10 str. iss. 16, art. 4548 Vol. 14 Aug. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.79:62-419:544.772 1996-1944 10.3390/ma14164548 72970755 RAZ_Sadl_Matej_2021.pdf RAZ_Sadl_Matej_2021.pdf 1 EC472AC0F93FC77DF8033F8CB3DCF0E8 368c4d03f3ee8c9093d94a2dc9b4ceb1103700261d2efb4709a8684e8f8957ed cc45f826-b4b8-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155315 https://www.mdpi.com/1996-1944/14/16/4548 1 9918427c-b4b8-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155314 Fakulteta za strojništvo 0 0 0
