20.500.12556/RUL-172020 Vpliv temperature in koncentracije elektrolita na učinkovitost plazemskega elektrolitskega poliranja The influence of electrolyte temperature and concentration on the efficiency of plasma electrolytic polishing V zaključni nalogi je obravnavan vpliv temperature in koncentracije elektrolita na učinkovitost plazemsko elektrolitskega poliranja (PeP) kovinskih vzorcev iz nerjavnega jekla. Namen raziskave je določiti ustrezne pogoje obdelave za doseganje čim boljše hrapavosti površine. Vsi vzorci so bili pred PeP peskani z namenom, da bi imeli čim bolj enako začetno hrapavost površine. Obdelava s PeP poteka pri konstantni napetosti 320 V in času trajanja obdelave štiri minute. Uporabljajo se različne koncentracije amonijevega sulfata (0,15 M–0,75 M) in temperature elektrolita (65–80 $^°$C). Meritve hrapavosti (Ra, Rz, Rp, Rv), mase, debeline in geometrije robov se izvajajo pred in po obdelavi. Rezultati kažejo, da se pri koncentracijah 0,15 M in 0,3 M pri vseh temperaturah hrapavost znatno zmanjša. Prav tako se dobri rezultati dosegajo pri 0,45 M in 80 $^°$C, kjer je površina gladka, izguba mase pa majhna. Koncentracija elektrolita ima večji vpliv na kakovost obdelave kot temperatura. The final thesis examines the influence of electrolyte temperature and concentration on the efficiency of plasma electrolytic polishing (PeP) of metallic stainless steel samples. The aim of the research is to determine the appropriate processing conditions to achieve optimal surface roughness. Prior to PeP, all samples were sandblasted in order to obtain the most uniform initial surface roughness possible. The PeP process is carried out at a constant voltage of 320 V and a treatment duration of four minutes. Various concentrations of ammonium sulfate (0.15 M–0.75 M) and electrolyte temperatures (65–80 $^°$C) are used. Surface roughness parameters (Ra, Rz, Rp, Rv), mass, thickness, and edge geometry are measured before and after treatment. The results show that at concentrations of 0.15 M and 0.3 M, surface roughness is significantly reduced at all temperatures. Good results are also achieved at 0.45 M and 80 $^°$C, where the surface is smooth and the mass loss is low. Electrolyte concentration has a greater influence on polishing quality than temperature. plazemsko elektrolitsko poliranje temperatura elektrolita koncentracija elektrolita hrapavost površine hitrost odnašanja materiala plasma electrolytic polishing electrolyte temperature electrolyte concentration surface roughness material removal rate true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-05 08:31:27 2025-09-05 08:31:28 2025-10-01 03:49:56 0000-00-00 00:00:00 2025 0 0 XII, 38 f. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536:544.018.4:621.9.048(043.2) 275503 248358147 43287.pdf 43287.pdf 1 B3B2E94C137B995DFE9A3EB8E9D1F323 18e80f26cff9ba2959129c0db01a15072d16e51cd413599b55d93a588c4b9aae ce2ebd72-8a21-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=215738 Fakulteta za strojništvo 0 0 0
