20.500.12556/RUL-144795 Enhancement of strength of adhesive bond between wood and metal using atmospheric plasma treatment Combinations of wood and metal are interesting hybrid composite materials, joining together the low density of wood with the stiffness and strength of metals. Different types of adhesives are used to connect wood and metal elements, but the compatibility between adhesives used and load-bearing materials must be sufficient, which often is challenging. In adhesive bonding technology, surface treatments are a crucial step in the process. In this study, an atmospheric plasma discharge was employed to enhance the adhesion strength of joints between common beech (Fagus sylvatica L.) wood, metals (steel and aluminum alloy), and four different types of adhesives. The optical properties of plasma discharges and its influence on treated substrates’ surface morphology depended on the inherent properties of the treated materials. X-ray photoelectron spectroscopy revealed the surface oxidation of all the materials after plasma treatment. Consequently, the surface free energy of all materials increased as well. The positive effect of the plasma treatment on the tensile shear strength of single-lap joints shows a high potential of atmospheric plasma treatment technology for enhancement of adhesives strength of joints combining wooden elements, wood and steel, or wood and aluminum alloys. In addition to that, expensive epoxy and polyurethane adhesives could be replaced by more affordable polyvinyl acetate and melamine-urea-formaldehyde adhesives, and still perform at equal levels if the plasma was applied prior to bonding. adhesives bonding metals wood plasma tensile shear strength surface lepila lepljenje les kovina plazma površina true false true Angleški jezik Slovenski jezik Članek v reviji 2023-03-13 11:41:07 2023-03-13 11:41:08 2023-04-14 03:49:43 0000-00-00 00:00:00 2020 0 0 Str. 6411-6424 iss. 11 Vol. 27 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8 1572-882X 10.1007/s10570-020-03212-8 15624707 s10570-020-03212-8_(5).pdf s10570-020-03212-8_(5).pdf 1 28D986E52C2E30485FDCC8960998AEC4 3c1f2def8f571591df82e721616042d522578d2708565ae2680875befe449327 806f66e5-d9c5-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167902 https://link.springer.com/article/10.1007/s10570-020-03212-8 1 837d029d-c18b-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167310 Biotehniška fakulteta 0 0 0
