20.500.12556/DiRROS-17289 Corrosion properties of aluminized 16Mo3 steel Chromium-molybdenum steel (16Mo3) is widely used in petroleum, gas, automotive, and construction industries due to its good oxidation resistance and mechanical properties at moderately elevated temperatures. The aim of the research was to evaluate the corrosion susceptibility of 16Mo3 steel in hot rolled and aluminized states. Aluminization was performed by diffusion pack aluminization process at 900°C/2h and 730°C/4h, respectively. Electrochemical corrosion testing included measuring open circuit potential (EOCP), linear polarization resistance (LPR), potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS) in potassium phosphate buffer (KH2PO4, pH = 7). Optical microscopy (OM), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS) were used for surface layer microstructure characterization before and after corrosion tests. It was demonstrated that corrosion resistance of aluminized steel increased substantially. Corrosion properties were related to the structure and properties of intermetallic phase (FeAl, FeAl2 and Fe2Al5) that formed on the surface of 16Mo3 steel. aluminide coatings aluminized steel aluminizing electrochemical corrosion investigation 16Mo3 steel aluminidne prevleke aluminizirano jeklo aluminiziranje elektrokemijske preiskave korozije jeklo 16Mo3 true false true Technical Faculty, Copper Institute Angleški jezik Slovenski jezik © authors, 2023 Neznano 2023-11-16 14:26:44 2023-11-16 14:26:44 2024-02-13 09:28:45 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Opis vira z dne 6. 4. 2023; str. 91-100 Iss. 1 Vol. 59 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-01-01 544.5/.6 2217-7175 10.2298/JMMB220927008K 148084739 https://www.doiserbia.nb.rs/Article.aspx?ID=1450-53392300008K#.ZC60tvZBwzu 1 67574758-847b-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23481 RAZ_Karpe_Blaz_2023.pdf RAZ_Karpe_Blaz_2023.pdf 1 C413660453620BCCC0D7ABDF64594E0F f3cb9b698a06526c333eb21d2fc3cccc04171e946f322242c0b08a060e5a2058 7909a9b5-847c-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23482 Zavod za gradbeništvo Slovenije 0 0 0
