20.500.12556/RUL-141941 Functional surface layer strengthening and wear resistance increasing of a low carbon steel by electrolytic-plasma processing Utrjevanje funkcijskih površinskih slojev in izboljševanje obrabne obstojnosti strojnih elementov iz maloogljičnega jekla s plazemsko elektrolizo The modified technology for strengthening the surface layer of low-carbon steel for machine components by electroplasma processing is proposed. This technology is to be used as an alternative carburizing method with subsequent hardening. The developed technology of strengthening by the proposed method is based on the author’s invention. The parameters of this process are given, resulting in a thickness of the reinforced surface layer of 1000 µm to 1700 µm. An increase in microhardness of 1.5 to 2 times (compared to the initial state) was observed. With hardening, chemical modification of the material’s surface layer occurs. The microstructure of the treated surface of the steel samples is characterised by a dark modified surface layer: a fine needle-like structure of martensitic origin under the dark layer transforms into an initial perlite-ferritic structure. The advantage of strengthening based on the electrolytic plasma processing consists of low energy consumption at high hardening speeds and the possibility of local processing of surface areas, especially large parts of complex shapes. In addition, the proposed surface treatment method using electrolytic plasma processing (EPP) not only achieves a smooth surface but also improves the service qualities of the components, specifically wear resistance. low-carbon compound steel strengthening electrolytic plasma processing maloogljično jeklo utrjevanje plazemska elektroliza prevleke inženiring površin obrabna obstojnost true false true Angleški jezik Slovenski jezik Članek v reviji 2022-10-12 08:35:29 2022-10-12 08:35:35 2022-10-13 04:03:52 0000-00-00 00:00:00 2022 0 0 Str. 542-551 no. 9 Vol. 68 Sep. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-09-01 621.357.1:66.087:669.14 0039-2480 10.5545/sv-jme.2022.147 125205507 Kombayev_..._-_Functional_surface_layer_strengthening_and_wear_resistance_increasing_of_a_low_carbon_steel_by_electrolytic-plasma_processing.pdf Kombayev_..._-_Functional_surface_layer_strengthening_and_wear_resistance_increasing_of_a_low_carbon_steel_by_electrolytic-plasma_processing.pdf 1 40A576751B7CE951FD663A4F11F94865 a50d67682c4b6a6a37578036c8d26f0754533e4b50133f422261673a642675be 5ed3bba0-49f8-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=163141 https://www.sv-jme.eu/sl/article/functional-surface-layer-strengthening-and-wear-resistance-increasing-of-a-low-carbon-steel-details-of-machines-by-electrolytic-plasma-processing/ 1 0c8d5a6e-49f8-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=163140 Fakulteta za strojništvo Strojniški vestnik 0 0 0
