XPS Analysis of Passive Film on Stainless Steel
Potentiodynamic, impedance measurements were carried out on 304 stainless steel in 0.5N, 1.0, 2.0 and 5.0 N H2SO4 solutions. X-ray photoelectron spectroscopic [XPS] studies carried out on 304 stainless steel in H2SO4 solutions revealed the existence of CrOOH, Cr2O3, -Fe2O3, FeOOH, Mn2O3, Mn3O4, MnS, Ni (OH)2, Ni2O3, NiO, sulphides. The passive film found to contain chromium oxide inner layer an...

متن کاملEffect of nitriding temperature on the nanostructure and corrosion properties of Nickel coated 304 stainless steel
Nickel films of 150 nm thickness were deposited on 304 stainless steel and post annealed under flow of nitrogen at different temperatures. The prepared samples were corrosion tested in 1.0 M H2SO4 solution using potentiodynamic polarization technique. Crystallographic and morphological structure of the samples were analysed by X-ray diffraction XRD and atomic force microscopy AFM respectively b...
