Samples of industrial-pressure die-cast aluminium–silicon alloy AlSi12Cu1(Fe) underwent anodization in as-die-cast surface conditions and after surface-grinding operations with material removal of 0.1, 0.5, and 1 mm. After surface grinding operations, the anodic layer thickness was significantly greater when subjected to a steady-state voltage of 35 V compared to that formed under a steady-state voltage of 20 V, showing an increase in the range of 2 to 2.5 times more than the thickness at 20 V. Additionally, anodizing under steady-state current mode (1.6 A·dm−2) yielded thicker layers compared to steady-state voltage mode (35 V, 1.6 A·dm−2 max) across all surface states (as-cast, ground). SEM-EDS analysis with element mapping revealed the subsequent effects of element distribution on anodic layer growth and structure. Grinding prior to anodization resulted in larger cavity sizes and lengths, attributed to microstructural variations induced by grinding. Grinding also exposed areas with slower solidification rates, fostering a homogeneous Al phase that facilitated enhanced oxide growth. Moreover, the formation of oxide was directly correlated with the presence of alloying elements, particularly silicon particles, which influenced the presence of the unanodized aluminium regions.}, year = {2024}, eissn = {2073-4352}, pages = {352-366} } @CONFERENCE{MTMT:34547816, title = {Challenges Associated with Anodizing Casting Al-Si Alloys}, url = {https://m2.mtmt.hu/api/publication/34547816}, author = {Razzouk, Emel and Török, Tamás}, booktitle = {PhD hallgatók anyagtudományi napja XXIII}, unique-id = {34547816}, year = {2023}, pages = {21-21} } @article{MTMT:34514260, title = {Additív technológiával előállított termékekben kialakuló maradó feszültségek vizsgálata}, url = {https://m2.mtmt.hu/api/publication/34514260}, author = {Kovács, Sándor Endre and Varga, László}, journal-iso = {BKL}, journal = {BÁNYÁSZATI ÉS KOHÁSZATI LAPOK (2023-)}, volume = {156}, unique-id = {34514260}, year = {2023}, eissn = {2498-9322}, pages = {10-15} } @article{MTMT:34499270, title = {Molibdát adalékos vasfoszfát konverziós réteg vizsgálata}, url = {https://m2.mtmt.hu/api/publication/34499270}, author = {Nagyné Fekete, Mónika and Kulcsár, Tibor and Török, Tamás}, journal-iso = {DOKTORANDUSZ ALMANACH}, journal = {DOKTORANDUSZ ALMANACH}, volume = {2023}, unique-id = {34499270}, issn = {2939-7294}, year = {2023}, pages = {65-74} } @article{MTMT:34498464, title = {Simulation testing of metal powders used in additive manufacturing technologies}, url = {https://m2.mtmt.hu/api/publication/34498464}, author = {Halápi, Dávid and Varga, László}, journal-iso = {DOKTORANDUSZ ALMANACH}, journal = {DOKTORANDUSZ ALMANACH}, volume = {2023}, unique-id = {34498464}, issn = {2939-7294}, year = {2023}, pages = {151-161} } @article{MTMT:34471927, title = {Áramlási vonalak vizsgálata deformációs mező meghatározására csőhúzás során}, url = {https://m2.mtmt.hu/api/publication/34471927}, author = {Palkovics, Miklós and Tóth, László}, journal-iso = {DOKTORANDUSZ ALMANACH}, journal = {DOKTORANDUSZ ALMANACH}, volume = {2}, unique-id = {34471927}, issn = {2939-7294}, year = {2023}, pages = {51-63} } @article{MTMT:34453362, title = {Comparison of metal powders shape and grain structure}, url = {https://m2.mtmt.hu/api/publication/34453362}, author = {Halápi, Dávid and Varga, László}, journal-iso = {DOKTORANDUSZ ALMANACH}, journal = {DOKTORANDUSZ ALMANACH}, volume = {2023}, unique-id = {34453362}, issn = {2939-7294}, year = {2023}, pages = {175-182} } @article{MTMT:34453228, title = {Examination of the porosity of 3D metal printed samples of metal powders used in additive manufacturing technologies}, url = {https://m2.mtmt.hu/api/publication/34453228}, author = {Halápi, Dávid and Varga, László}, journal-iso = {DOKTORANDUSZ ALMANACH}, journal = {DOKTORANDUSZ ALMANACH}, volume = {2023}, unique-id = {34453228}, issn = {2939-7294}, year = {2023}, pages = {162-173} } @article{MTMT:34452612, title = {Additive manufacturing mistakes: an overview of possible errors in Laser Power Bed Fusion processes}, url = {https://m2.mtmt.hu/api/publication/34452612}, author = {Kovács, Sándor Endre and Varga, László}, journal-iso = {DOKTORANDUSZ ALMANACH}, journal = {DOKTORANDUSZ ALMANACH}, volume = {2023}, unique-id = {34452612}, issn = {2939-7294}, year = {2023}, pages = {184-188} }
