20.500.12556/RUL-127264 Improvement of corrosion resistance of AA2024-T3 using femtosecond laser peening without protective and confining medium This work reports for the first time the effect of femtosecond laser shock peening (fLSP) without a sacrificial overlay under atmospheric conditions (no confinement) on the corrosion behaviour of AA2024-T3. After fLSP and additional exposure to air a superhydrophobic state (θ=160 ± 4°) is achieved. Moreover, fLSPed corrosion-resistant surface contributes to increased polarization resistance, reduced corrosion current and lower anodic dissolution, with long-term stability in aggressive chloride solution. Furthermore, SEM/EDS characterisation reveals reduction in pitting and complete eradication of intergranular corrosion (IGC) attack due to reduced metal/electrolyte contact area and homogeneous, refined microstructure which prevents chain-link IGC propagation. aluminium aluminium alloy 2024-T3 polarization scanning electron microscope - SEM intergranular corrosion pitting corrosion aluminij aluminijeva zlitina 2024-T3 polarizacija vrstični elektronski mikroskop - SEM interkristalna korozija jamičasta korozija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-06-01 08:10:40 2021-06-01 08:10:44 2025-03-13 10:33:55 0000-00-00 00:00:00 2018 0 0 Str. 46-55 Vol. 143 Oct. 2018 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 2018-04-17 2018-08-07 2018-08-14 2020-10-01 620.1(045) 0010-938X 10.1016/j.corsci.2018.08.030 16218651 RAZ_Trdan_Uros_2018.pdf RAZ_Trdan_Uros_2018.pdf 1 AB4ECF64BACA82DACCC0B59C11B33F6C 5b6ea34b94b19abe576c83e21a2aca41a68367360292abb79613de54ef6b423b 7b3ac095-c2a4-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143578 https://www.sciencedirect.com/science/article/pii/S0010938X18307030?via%3Dihub#! 1 07b86c0d-c2a0-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143576 Fakulteta za strojništvo 0 0 0
