20.500.12556/RUL-126437 Tribology of solid-lubricated liquid carbon dioxide assisted machining An investigation is made into the lubrication capabilities of solid-lubricated liquid carbon dioxide (LCO2) in comparison to flood lubrication, straight LCO2 and oil lubricated LCO2 (MQL). The coefficient of friction is determined via tribological experiments, similar to machining, using an open tribometer which features an uncoated carbide insert sliding against a workpiece. Tribological experiments reveal superior performance of solid-lubricated LCO2. The milling experiments as well indicate that solid-lubricated LCO2 significantly reduces wear. The machined surface topography is examined using high-magnification SEM, which shows no presence of adhered solid particles on the workpiece surface, providing a completely dry machining process. machining lubrication friction odrezavanje mazanje trenje true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-22 10:32:05 2021-04-22 10:32:08 2022-09-05 03:55:17 0000-00-00 00:00:00 2020 0 0 Str. 69-72 iss. 1 Vol. 69 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.92:621.89(045) 0007-8506 10.1016/j.cirp.2020.04.033 15739395 RAZ_Pusavec_Franci_2020.pdf RAZ_Pusavec_Franci_2020.pdf 1 7BD42ECB7A56F1B4FB81FDDD5F08F70D f12cdb811dd552e9439d93402ca89163e0f5e2d07802427300344e4cb5418c9e adc5151d-a346-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142402 https://www.sciencedirect.com/science/article/pii/S000785062030055X 0 3a2d074b-a345-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142401 Fakulteta za strojništvo 0 0 0
