  • Raman investigation of sol-gel anticorrosion coatings on electronic boards = Ramanske raziskave sol-gel protikorozijskih prevlek na elektronskih vezjih
    Rauter, Aleksander, 1983- ...
    Due to its non-destructive character and high spatial resolution, confocal Raman spectroscopy was found to be a good technique for detecting spray-deposited sol-gel coatings on electronic boards ... (EBs). 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)propyl]tetrasulphide (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.
