20.500.12556/DiRROS-21098 Influence of surface preparation of aluminum alloy AW-5754 and stainless steel X5CRNI18-10 on the properties of bonded joints Adhesive bonding has proven to be a reliable method of joining materials, and the development of new adhesives has made it possible to use bonding in a variety of applications. This article addresses the challenges of bonding metals such as the aluminum alloy EN AW-5754 and the stainless steel X5CrNi18-10. In this study, the effects of laser cleaning and texturing on the surface properties and strength of two bonded joints were investigated and compared with mechanical preparation (hand sanding with Scotch-Brite and P180 sandpaper). The bonded joints were tested with three different epoxy adhesives. During the tests, the adhesion properties of the bonded surface were determined by measuring the contact angle and assessing the wettability, the surface roughness parameters for the different surface preparations, and the mechanical properties (tensile lap-shear strength). Based on the strength test results, it was found that bonded joints made of stainless steel had 16% to 40% higher strength than aluminum alloys when using the same adhesive and surface preparation. Laser cleaning resulted in maximum shear strength of the aluminum alloy bond, while the most suitable surface preparation for both materials was preparation with P180 sandpaper for all adhesives. adhesive bonding surface preparation aluminum alloy AW-5754 stainless steel X5CrNi18-10 epoxy adhesives lepljenje priprava površin aluminijeva zlitina AW-5754 nerjavno jeklo X5CrNi18-10 epoksi lepila true false true MDPI Švica Angleški jezik Slovenski jezik © 2024 by the authors Neznano 2024-12-20 12:18:19 2024-12-20 12:18:19 2024-12-21 03:36:18 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 30. 5. 2024; str. 1-19 iss. 11, [article no.] 2561 Vol. 17 May 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-05-01 621.792:669.715+669.14.018.8 1996-1944 10.3390/ma17112561 197248003 RAZ_Zdravkovic_Natasa_2024.pdf RAZ_Zdravkovic_Natasa_2024.pdf 1 22BC41B9882DD0E1820C1925B2A4EE06 7831e60dd8f60a94426e7df65fa81fafbadb49cd991b17058a37e137cd37349a fb27ce39-bec6-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29904 https://www.mdpi.com/1996-1944/17/11/2561 1 1f2163cc-bec4-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29903 Inštitut za kovinske materiale in tehnologije 0 0 0
