20.500.12556/RUL-168304 Prisilno izpiranje pri plazemskem elektrolitskem poliranju Forced flushing in plasma electrolytic polishing Plazemsko elektrolitsko poliranje je postopek končne obdelave kovinskih površin, namenjen izboljšanju njihove hrapavosti. Pri poliranju notranjih površin se pojavljajo izzivi, saj zaradi učinka Faradejeve kletke nekatere površine ostanejo nepolirane. V okviru naloge je bil zato zasnovan in testiran sistem za prisilno izpiranje, ki omogoča enakomerno dovajanje elektrolita v kritične predele obdelovancev. Razviti in analizirani so bili trije različni sistemi, pri čemer je bil na podlagi večkriterijske analize izbran najučinkovitejši, ki je bil nato izdelan in preizkušen. Eksperimentalni rezultati so pokazali, da sistem izboljša enakomernost obdelave in omogoča učinkovitejše poliranje, vendar so se pri določenih preizkusih pojavile težave z globino poliranja, kar kaže na potrebo po nadaljnjih raziskavah in izboljšavah. Plasma electrolytic polishing is a surface finishing process designed to improve the roughness of metallic surfaces. However, challenges arise when polishing internal surfaces, as some areas remain unpolished due to the Faraday cage effect. To address this issue, a forced flushing system was designed and tested, enabling uniform electrolyte delivery to critical areas of the workpieces. Three different systems were developed and analyzed, with the most effective one selected based on a multi-criteria analysis. The chosen system was then manufactured and experimentally tested. The results demonstrated that forced flushing enhances processing uniformity and enables more effective polishing. However, certain tests revealed issues with polishing depth, highlighting the need for further optimizations and research. plazemsko elektrolitsko poliranje Faradayeva kletka prisilno izpiranje slepe izvrtine površinska hrapavost globina poliranja plasma electrolytic polishing Faraday cage forced flushing blind holes surface roughness polishing depth true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-04-09 07:30:05 2025-04-09 07:30:09 2025-04-10 04:12:53 0000-00-00 00:00:00 2025 0 0 XX, 49 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.7.024:620.19:621.9.048(043.2) 270570 231935747 38771.pdf 38771.pdf 1 1829F0F31D80D5553A37637EEDAFCB54 96d60d0817891c6e7878f2efe2521e57f1f58589e2def04f0e352f90a03eda5f a10167ab-1502-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201503 Fakulteta za strojništvo 0 0 0
