20.500.12556/RUL-105525 Transition from superhydrophilic to superhydrophobic state of laser textured stainless steel surface and its effect on corrosion resistance This work investigates the evolution from superhydrophilic to superhydrophobic surface state on corrosion behaviour of SS316L produced by Nd:YAG nanosecond direct laser texturing (DLT). Results confirm perfect correlation among wettability and corrosion, hence superhydrophobic surface with a contact angle of 168 +/- 3.0° reflects in enhanced passivity, lower anodic dissolution and corrosion current reduction. Characterization of the corrosion attack by 3D microscopy reveals high sensitivity of superhydrophilic surfaces on corrosion propagation direction in regard to the laser beam passage (90°/0°). However, this trend completely diminishes with superhydrophobic development. Further, DLT also completely prohibits intergranular corrosion detected with the non-processed sample. stainless steel polarization SEM intergranular corrosion passivity pitting corrosion lasersko teksturiranje nerjavno jeklo polarizacija interkristalna korozija pasivacija jamičasta korozija true false true Angleški jezik Slovenski jezik Članek v reviji 2018-12-04 14:26:29 2018-12-04 14:26:31 2025-02-18 12:34:41 0000-00-00 00:00:00 2017 0 0 Str. 21-26 Vol. 123 Jul. 2017 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.178.3:621.7(045) 0010-938X 10.1016/j.corsci.2017.04.005 15482907 5881607 RAZ_Trdan_Uros_i2017.pdf RAZ_Trdan_Uros_i2017.pdf 1 1214B40CA1103C18654C1E465202C771 51d496ff5bbaea9a8dda92b22b5f50dc7316abc45c1e7e615277cfd5590d00bd 315f9c52-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116192 http://www.sciencedirect.com/science/article/pii/S0010938X17300069 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116191 Fakulteta za strojništvo 0 0 0
