20.500.12556/RUL-98469 Controlling the stainless steel surface wettability by nanosecond direct laser texturing at high fluences This work investigates the influence of the direct laser texturing at high fluences (DLT-HF) on surface mor - phology, chemistry, and wettability. We use a Nd:YAG laser (gamma= 1064 nm) with pulse duration of 95 ns to process stain- less steel surface. The surface morphology and chemistry after the texturing is examined by using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and electron backscatter diffraction (EBSD), while the surface wettability is evaluated by measuring the static contact angle. Immediately after the texturing, the surface is superhydrophilic in a saturated Wenzel regime. However, this state is not stable and the superhydrophilic-to-superhy - drophobic transition happens if the sample is kept in atmos- pheric air for 30 days. After this period, the laser-textured stainless steel surface expresses lotus-leaf-like behavior. By using a high-speed camera at 10,000 fps, we measured that the water droplet completely rebound from this superhydro- phobic surface after the contact time of 12 ms. surface engineering laser microstructuring surface functionalization inženiring površin lasersko mikrostrukturiranje funkcionalizacija površin true false false Angleški jezik Slovenski jezik Delo ni kategorizirano 2017-12-04 08:51:05 2018-02-28 10:53:31 2025-03-02 15:45:52 0000-00-00 00:00:00 2107 0 0 Str. 1-8 Vol. 123, art. 766 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2018-11-13 535(045) 0947-8396 10.1007/s00339-017-1392-5 15750427 14196007 Gregorcic_ID=_15750427.pdf Gregorcic_ID=_15750427.pdf 1 4ABA785A8BCF229AC25956FC2D006386 4a9a63736ecda3b1db37f6a1764f1c394f620de6b26588753acd55787cd1034c 67d288b6-a1b4-11eb-a523-00155dcfd717 20.500.12556/rul/2c122074-c891-4c41-87de-4f224619b487 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=107754 Fakulteta za strojništvo 0 0 0
