Apr 9, 2021 · Abstract X-ray Photoelectron Spectroscopy and Time-of-Flight Secondary Ion Mass Spectrometry were combined to characterize the surface oxides (native oxides and passive …

Sep 30, 2003 · The surface films of high Cr-Ni ferritic and austenitic stainless steels, which have 21–39 wt.% chromium and 5–28 wt.% nickel, after grinding with SiC paper down to grit 1200, …

In principle, the oxidation states of nickel in the surface region can be determined from the binding energies (BE) and their chemical shifts in XPS spectra.

We firstly chose the Ni60Nb20Zr20 and Ni57Nb19Zr19Ta5 glassy alloys to measure the corrosion rates in boiling 6 N HNO3 solutions with and without 5 g/l Cr6þ for 2 weeks.

The diffusion of elements from the alloy into the oxide and the redox reactions may cause modi-fications of the physical surface/interface morphology and chemical environment and lead to …

Aug 17, 2022 · Abstract This study uses nickel nanoparticles coated on the nickel–chromium (Ni–Cr) alloy by the electrodeposition technique to protect the alloy against corrosion.

Mar 29, 2021 · X-ray Photoelectron Spectroscopy and Time-of-Flight Secondary Ion Mass Spectrometry were combined to characterize the surface oxides (native oxides and passive …
