20.500.12556/RUL-171241 Doseganje ustrezne topografije struženih keramičnih diskov s pomočjo UZ asistence za namen izboljšanja adhezijskih lastnosti površine Achieving appropriate topography of turned ceramic disks using ultrasonic assistance for the purpose of improving surface adhesion properties Po mehanski obdelavi ZnO varistorskih diskov je treba na čelno površino nanesti aluminijev prevodni sloj, ki mora imeti dobro adhezijo. Ker gladka čelna površina po klasičnem struženju ne omogoča zadostnega oprijema, jo dodatno teksturiramo s struženjem z ultrazvočno asistenco. V okviru magistrske naloge so bili izvedeni poizkusi z različnimi kombinacijami rezalnih parametrov. Prve teste smo zaradi višje obdelovalnosti izvedli na medenini, nato pa postopke prenesli na keramiko. Rezultate smo ovrednotili s trgalnimi testi in MATLAB analizo ter na podlagi tega določili optimalne pogoje obdelave. After the mechanical processing of ZnO varistor discs, a conductive aluminum layer must be applied to the front surface, which requires good adhesion. Since the smooth surface resulting from conventional turning does not provide sufficient bonding, additional texturing is performed using ultrasonic-assisted turning. As a part of the master's thesis, experiments were conducted using various combinations of cutting parameters. Initial tests were carried out on brass due to its better machinability, and the procedures were later applied to ceramic discs. The results were evaluated using pull-off tests and MATLAB analysis, which enabled the determination of optimal machining conditions. keramični disk varistor struženje obdelava z ultrazvočno asistenco rezalna hitrost trgalni test ceramic disc varistor turning ultrasonic-assisted machining cutting speed pull-off test true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-08-21 08:30:41 2025-08-21 08:30:46 2026-07-24 08:45:22 0000-00-00 00:00:00 2025 0 0 XXII, 80 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2027-08-20 621.9.048:621.315.612:519.6(043.2) 274501 246176003 42903.pdf 42903.pdf 1 0967D9271639920D25C3AD4C763DD05E 887306ff6cb6dfcda4774933ccc07a1ebbb6aa48a6f15d9db31c69f97b817b6c 45a0916b-7e58-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214432 Fakulteta za strojništvo 0 0 0
