“…In another study, ZrN thin lm coating by unbalanced magnetron sputtering on 304 SS increased the passivation behavior by at least 100 times relative to bare 304 SS by looking at the decrease in the corrosion current density 11 . Besides, titanizing 12 , gamma-alumina 13 , zirconia 14,15 , titanium boron nitride thin lms 16 , WO 3 nano akes coated with TiO 2 nanoparticles 17 , borate glass 18 , amorphous boron 19 , amorphous hybrid silane reinforced with ZnO 20 , FeCo 2 O 4 nanowire arrays 21 , polypyrrole-sulfonated melamine formaldehyde nanocomposites 22 , polypyrrole doped with dodecylbenzenesulphonic acid 23 , polypyrrole-Al 2 O 3 composite 24 , poly(vinylcarbazole)/alumina nanocomposite 25 , polyterthiophene 26 , polyaniline and its derivatives 27 , superhydrophobic electroactive epoxy 28 , polyaniline-graphene oxide 29 , nickel hydroxide-graphene oxide 30 , carbon nanotube/nano ber 31 , organic-inorganic hybrid sol-gel silica 32 are coated on 316 series stainless steels to improve their performance for a range of applications.…”
