20.500.12556/RUL-127262 Electrochemical and DFT studies of laser-alloyed TiB2/TiC/Al coatings on aluminium alloy Microstructural and corrosion characteristic of laser-alloyed TiB2/TiC/Al composite coatings on 6082-T651 aluminium substrate were investigated. Density functional theory was used to study the chemical bonding of TiC and TiB2. The results confirmed a compact TiB2/TiC/Al-coating with low porosity, without any cracks and with good long-term stability against corrosion. Moreover, EIS and CP results confirmed enhanced corrosion resistance of laser-alloyed TiB2/TiC/Al coatings, with lower coating capacitance, increased polarisation resistance and reduced corrosion current density compared to the Al 6082 substrate. Although, all the laser-alloyed coatings experienced pitting attack, the intensity of pitting attack was substantially reduced compared to the substrate material. laser coating of aluminum alloy EN AW 6082-T651 TiC-TiB2 pitting corrosion lasersko oplastenje aluminijeve zlitine EN AW 6082-T651 TiC-TiB2 jamičasta korozija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-05-31 14:16:57 2021-05-31 14:16:58 2025-03-13 10:43:08 0000-00-00 00:00:00 2018 0 0 Str. 18-27 Vol. 136 May 2018 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 2017-01-03 2018-02-16 2018-02-20 2020-05-15 669.715.018.8(045) 0010-938X 10.1016/j.corsci.2018.02.028 15930395 RAZ_Ravnikar_Dunja_2018.pdf RAZ_Ravnikar_Dunja_2018.pdf 1 E9E12B08E573C9B618A47AD2E463E64F 5ff96b443cfdde81020b92b806403faaf8f2553d63819134e41dfce77dfbaeee 2612996d-c20e-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143574 https://www.sciencedirect.com/science/article/pii/S0010938X16314561 1 074c66e8-c20a-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143573 Fakulteta za strojništvo 0 0 0
