The aim of this work was to investigate how the mechanical and tribological properties of this alloy can be improved by applying an anodizing process. The properties of the oxide layer formed by anodizing using oxalic acid at low temperatures were characterized by different analytical and tribological methods. The combination of tribological methods with standard measurement techniques—such as hardness measurement, layer thickness measurement, as well as the analysis of the morphological characteristics—was used to track the layer evolution during wear developments.}, year = {2023}, eissn = {2079-6412}, orcid-numbers = {Windisch, Márk/0009-0004-3413-2471; Török, Mátyás/0009-0008-6298-6625; Nguyen Quang, Chinh/0000-0002-6610-7308; Vida, Ádám/0000-0002-0519-2772} } @article{MTMT:33761895, title = {Kender – PLA biokompozit filament 3D nyomtatásának vizsgálata}, url = {https://m2.mtmt.hu/api/publication/33761895}, author = {Csörgő, Zsombor László and Kovács, Sándor and Topa, Martin and Rédey, Soma}, journal-iso = {MŰANYAG- ÉS GUMIIPARI ÉVKÖNYV}, journal = {MŰANYAG- ÉS GUMIIPARI ÉVKÖNYV}, volume = {21}, unique-id = {33761895}, issn = {1589-6269}, year = {2023}, pages = {36-38} } @article{MTMT:33761834, title = {Kender - PLA kompozit filament 3D nyomtatásának elemzése}, url = {https://m2.mtmt.hu/api/publication/33761834}, author = {Csörgő, Zsombor László and Kovács, Sándor and Topa, Martin and Rédey, Soma}, journal-iso = {ANYAGVIZSGÁLÓK LAPJA}, journal = {ANYAGVIZSGÁLÓK LAPJA}, unique-id = {33761834}, issn = {1215-8410}, year = {2022}, eissn = {1787-5072}, pages = {20-25} } @article{MTMT:33205972, title = {Kompozit filamentek 3D nyomtathatósági vizsgálata}, url = {https://m2.mtmt.hu/api/publication/33205972}, author = {Topa, Martin and Tóka, Bence and Béres, Levente and Kovács, Sándor}, journal-iso = {ANYAGVIZSGÁLÓK LAPJA}, journal = {ANYAGVIZSGÁLÓK LAPJA}, unique-id = {33205972}, issn = {1215-8410}, year = {2022}, eissn = {1787-5072}, pages = {48-53} } @article{MTMT:32815145, title = {Végeselemes szimulációkkal támogatott anyagfejlesztési projekt bemutatása}, url = {https://m2.mtmt.hu/api/publication/32815145}, author = {Ungár, Péter and Kovács, Sándor and Havas, Zsuzsanna}, journal-iso = {MŰANYAG- ÉS GUMIIPARI ÉVKÖNYV}, journal = {MŰANYAG- ÉS GUMIIPARI ÉVKÖNYV}, volume = {2022}, unique-id = {32815145}, issn = {1589-6269}, year = {2022}, pages = {80-82} } @article{MTMT:32518397, title = {Mezőgazdasági melléktermékek használatával készült kompozitok vizsgálata evőeszközök gyártásához}, url = {https://m2.mtmt.hu/api/publication/32518397}, author = {Ungár, Péter and Kovács, Sándor and Havas, Zsuzsanna}, journal-iso = {GÉP}, journal = {GÉP}, volume = {2021/3-4.}, unique-id = {32518397}, issn = {0016-8572}, year = {2021}, pages = {65} } @article{MTMT:31950236, title = {Coupled numerical method for rolling contact fatigue analysis}, url = {https://m2.mtmt.hu/api/publication/31950236}, author = {Szávai, Szabolcs and Kovács, Sándor and Bézi, Zoltán and Dražan, Kozak}, doi = {10.17559/TV-20201117124940}, journal-iso = {TEH VJESN}, journal = {TEHNICKI VJESNIK-TECHNICAL GAZETTE}, volume = {28}, unique-id = {31950236}, issn = {1330-3651}, year = {2021}, eissn = {1848-6339}, pages = {1560-1567}, orcid-numbers = {Szávai, Szabolcs/0000-0002-8311-2870} } @article{MTMT:31833469, title = {Comparison of Simplified and Finite Element Analysis on Cold Flat rolling}, url = {https://m2.mtmt.hu/api/publication/31833469}, author = {Szűcs, Máté and Bobor, Kristóf and Szabó, Gábor and Krállics, György and Kovács, Sándor}, journal-iso = {MATER SCI ENGINEERING MISKOLC}, journal = {MATERIALS SCIENCE AND ENGINEERING: A PUBLICATION OF THE UNIVERSITY OF MISKOLC}, volume = {45}, unique-id = {31833469}, issn = {2063-6792}, year = {2020}, pages = {271-283} } @article{MTMT:31607117, title = {Temperature Variation at Solid-Fluid Interface of Thin Film Lubricated Contact Problems}, url = {https://m2.mtmt.hu/api/publication/31607117}, author = {Szávai, Szabolcs and Kovács, Sándor}, doi = {10.3390/pr8080922}, journal-iso = {PROCESSES}, journal = {PROCESSES}, volume = {8}, unique-id = {31607117}, issn = {2227-9717}, abstract = {Many calculating methods have been already developed for solving contact problems of parts such as gears, cams, and followers under fluid film lubrication conditions considering the temperature and pressure dependence. Similarly, the determination of the elasto-hydrodynamic pressure distribution the processes taking place in the lubricant and the contacting bodies, as well as in their environment, have to be dealt with simultaneously for the determination of the temperature field. A system of equation for the modelling of thermo-elastohydrodynamic lubrication between two contacting bodies containing hydrodynamic, thermodynamic, and strength problems is a highly non-linear system which becomes even more so if the temperature and pressure dependence of the material properties are considered. To solve this system, scientists started to use the finite element formulation in the 1960s and it was found to be a promising and reliable method. Earlier, the lubrication analysts used only the h-version finite element method (h-FEM) till 1991, when the first usage of the p-version finite element method (p-FEM) was published in the literature. In order to reduce the problem, in case of point or line contact, the contact bodies can be handled as semi-infinite ones. Following this simplification that had been successfully applied for the gap size determination, a substructure model was defined using analytical solution of the moving heat source. Instead of an iterative way between the solid and fluid problem, in this paper we present an efficient solution when thermal model for lubricant and surfaces were coupled and solved by a direct numerical method in one step.}, year = {2020}, eissn = {2227-9717}, orcid-numbers = {Szávai, Szabolcs/0000-0002-8311-2870} } @inproceedings{MTMT:33228517, title = {COMPARISON OF DIFFERENT PLATING TECHNOLOGY OF BONDING PROPERTIES OF MULTILAYER ALUMINIUM SHEETS}, url = {https://m2.mtmt.hu/api/publication/33228517}, author = {Szabó, Gábor and Mikó, Tamás and Kovács, Sándor}, booktitle = {MultiScience - XXXIII. microCAD International Multidisciplinary Scientific Conference}, doi = {10.26649/musci.2019.086}, unique-id = {33228517}, year = {2019} }
