20.500.12556/RUL-125701 Protective alumina coatings prepared by aerosol deposition on magnetocaloric gadolinium elements Korundna zaščita magnetokaloričnih hladilnih elementov pripravljena z metodo nanašanja delcev v curku aerosola In this work the preparation of a protective insulating alumina coating on magnetocaloric gadolinium elements was investigated. In order to prepare a dense ceramic coating at room temperature the aerosol deposition technique was used. The study reveals that the powder morphology and particle size are important parameters that influence the deposition efficiency, powder packing and consequently also the density and functional properties of the alumina coating. The optimal powder pre-deposition treatment includes heating the powder to 1150 °C, followed by milling. The deposition of this powder resulted in the preparation of dense alumina coatings with a low specific electrical conductivity of 6.4.10-14 [Omega]-1m-1. protective alumina coating aerosol deposition magnetocaloric gadolinium korundne zaščitne prevleke nanašanje delcev v curku aerosola magnetokalorični gadolinij true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-02 14:35:38 2021-04-02 14:35:44 2022-09-05 03:52:09 0000-00-00 00:00:00 2019 0 0 Str. 177-182 no. 3 Vol. 49 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.5(045) 0352-9045 URN:NBN:SI:doc-OFHVNHSU 16935195 1220612 RAZ_Sadl_Matej_2019.pdf RAZ_Sadl_Matej_2019.pdf 1 26F72F78FC45F0FC6E8C6589920DC6FF 167ca50d8be349627bc09cba4f1ba401e4c4e9c9da906d773ef37b52968a09f4 c58e1606-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141553 https://doi.org/10.33180/InfMIDEM2019.306 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141552 Fakulteta za strojništvo 0 0 0
