20.500.12556/DKUM-27361 Nanofoils for soldering and brazing in dental joining practice and jewellery manufacturing Nanofolije za lotanje pri zobozdravniškem delu in izdelavi nakita This paper describes the development of novel, reactive Al-Au nano-multilayered foils, their possible application in different fields and a discussion of the nano-foils' suitability for dental and jewellery applications. Moreover, this study includes the rapid joining of similar and dissimilar materials, by placing multilayer nano-foils and two layers of solder or braze. The foils precisely control the instantaneous release of heatenergy for the joining and act as a controllable local heat source. The reactive foils' thickness is in the range 10 nm to less than 100 nm and they contain many nanoscale layers that alternate between materials with high mixing heats, such as Al and Au. The foil between the two solder/braze layers melts the solder/braze with the heat generated by the reaction and bonds the components. The use of reactive foils eliminates the need for a furnace and dramatically increases the soldering/brazing heating rate of the components being bonded. Thus, ceramics and metals can be fused over required areas without the thermal stresses that are encountered in furnace soldering or brazing. In addition, a completely new plasma technology is proposed for the manufacturing of nano-foils and the first results of the preliminary experimental testing are presented. Članek opisuje razvoj nanoplastnih reaktivnih Al-Au-folij, njihovo uporabo na različnih področjih in razprava o uporabi v zobni tehniki in pri izdelavi nakita. Študija vključuje hitro spajanje podobnih in različnih materialov s postavitvijo večplastnih nanofolij ter plasti lota med oba dela za spajanje. Folije kontrolirajo hipno sprostitev toplotne energije za spajanje in delujejo kot lokalni vir toplote. Reaktivne folije z debelino od 10 nm do 100 nm so izmenoma iz materialov, ki imajo veliko toploto mešanja, npr. Al in Au. Folija z reakcijsko toploto raztali obe plasti lota in spoji obe lotani komponenti. Pri uporabi reaktivnih folij je peč nepotrebna, zato se zelo poveča hitrost spajanja lotanih komponent. Keramiko in kovine je mogoče spajati na določenih površinah brez toplotnih napetosti, ki nastanejo pri lotanju s segrevanjem v peči. Sugerirana je tudi nova plazemska tehnologija zaizdelavo nanofolij in predstavljeni so prvi rezultati praktičnih preizkusov. ceramic-metal bonding low-temperature nano-foils plasma technology dentistry jewellery spajanje keramika-kovina nizke temperature nanofolije plazemska tehnologija zobotehnika nakit true false true Angleški jezik Slovenski jezik Znanstveno delo 2012-06-01 10:47:04 2012-06-01 10:47:04 2022-04-15 13:43:58 2021-04-11 03:25:50 2009 0 0 str. 3-9 št. 1 Letn. 43 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1580-2949 669.71'21:621.791.3:616.314-089.28:671.12 106193664 13021718 1580-2949 URN:SI:UM:DK:NLKDFFX6 Materiali_in_Tehnologije_2009_Raic_et_al._Nanofoils_for_Soldering_and_Brazing_in_Dental_Joining_Practice_and_Jewellery_Manufacturing.pdf Materiali_in_Tehnologije_2009_Raic_et_al._Nanofoils_for_Soldering_and_Brazing_in_Dental_Joining_Practice_and_Jewellery_Manufacturing.pdf 1 5FDEEE83B28CB2689E3F9AEDCC54808B 4423d1124da0a01226a5208c5f3a85fd11f2d75de3dd9d44d6646433ecac6b36 ff68bafa-7c0d-11eb-bb7a-00155d0001ca 20.500.12556/dkum/bf7096ac-3c2c-472a-8eb4-89442336aab1 https://dk.um.si/Dokument.php?lang=slv&id=109938 http://mit.imt.si/Revija/izvodi/mit091/raic.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=109937 Fakulteta za strojništvo 0 0 0
