EBs are demanding substrates to cover because of their non-flat surfaces, containing various metals, alloys, pins and other elements. Nanocomposite coatings were made on the basis of bis end-capped organic-inorganic hybrid precursors, bis-(3-(3-(3-triethoxysilyl)propyl)thioureido)propyl terminated polydimethylsiloxane (PDMSTU) and bis-3-(triethoxysilyl)propyltetrasulphide (BTESPT), imparting a hydrophobic character to the produced anticorrosion coatings. Reactions of hydrolysis and condensation were initiated with an addition of the 0.1 M HCl catalyst. Nanoparticles were introduced in the sols as trisilanol-heptaisooctyl-polyhedral oligomeric silsesquioxanes (up to 5 nm). The obtained sols were spray deposited on the test substrate, i.e., the aluminium alloy AA 2024, and also on EB. The coatings on AA 2024 were used for potentiodynamic electrochemical and surface (SEM, AFM) characterisation of the prepared coatings. Extensive Raman spectroscopy measurements of the uncovered and covered EBs revealed that the sol-gel coatings on various elements and pins of EBs are clearly visible in the Raman spectra and that this is an appropriate technique for detecting the coatings on such demanding substrates"},{"@xml:lang":"sl","#text":"Glede na nedestruktivni značaj in veliko prostorsko ločljivost ramanske spektroskopije smo to tehniko študirali s stališča možnosti detekcije napršenih sol-gel prevlek na elektronska vezja. Elektronska vezja so zahtevne podlage, kar zadeva njihovo prekrivanje, saj njihova površina ni ravna, na njej se nahajajo različne kovine, zlitine, konice in drugi elementi. Nanokompozitne prevleke smo pripravili na osnovi dvostransko funkcionaliziranih organsko-anorganskih prekurzorjev bis-(3-(3-(3-trieto- ksisilil)propil)tioureido)propil zaključenega poli(dimetilsiloksana) (PDMSTU) in bis-(3-(trietoksisilil)propil)tetrasulfida (BTESPT), ki v pripravljene protikorozijske prevleke vneseta hidrofoben značaj. Reakcije hidrolize in kondenzacije smo začeli z dodatkom katalizatorja 0,1 M HCl. Nanodelce smo v sole vključili kot trisilanol-heptaizooktil-poliedrične oligomerne silseskvioksane (do 5 nm). Tako pripravljene sole smo nanesli na preizkusne podlage, in sicer na aluminijevo zlitino AA 2024 in tudi elektronska vezja. Prevleke na AA 2024 smo uporabili za potenciodinamične elektrokemijske meritvein površinsko (SEM, AFM) karakterizacijo. Obširne ramanske meritve nezaščitenih in zaščitenih elektronskih vezij pa so pokazale, da lahko sol-gelprevleke na različnih elementih in konicah elektronskih vezij jasno ugotovimo v ramanskih spektrih in da je zato ta tehnika primerna za detekcijo prevlek na zahtevnih podlagah"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-OJBH4ZLD","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-OJBH4ZLD"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-OJBH4ZLD/6e5b0bef-f0fb-47eb-9186-51ef0bd2fe0a/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-OJBH4ZLD/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-OJBH4ZLD"}}}}
