Abstract X‐ray photoelectron spectroscopy (XPS) has been used to investigate the electrochemical and thermal oxidation of titanium nitride (TiN) coatings prepared by physical vapour deposition (PVD) at 200°C. Electrochemical TiN was carried out various potentials in phthalate buffer solution (pH 5.0). Evaluation XPS Ti 2p N 1s spectra showed presence nitride, oxynitride oxide species layer formed anodic oxidation. The TiO 2 proceeds through formation a mixed oxynitride/oxide layer, which...
In situ electrochemical scanning tunneling microscopy (STM) measurements of the anodic oxidation Cu(111) in 0.1 M NaOH are reported. Anodic is preceded, underpotential range, by adsorption an ordered layer assigned to OH species. This adlayer a precursor oxide growing at higher potential with copper surface reordering mimic structural arrangement (111) oriented Cu2O oxide. range Cu(I) oxidation, Cu2O(111) film formed faceted, and most likely hydroxylated, surface.

Abstract Pit nucleation and repassivation on iron nickel has been examined by potentiostatic transient measurements. Very short times for the of corrosion pits some ms to 100 prepassivated specimens have observed. Addition picrate electrolyte can stop pit well at all potentials completely, but cannot prevent already existing pits. The results are explained adsorption‐ film breaking theory give contradiction penetration mechanism. in an early stage development takes Δ T r = 1 according...
Passive layers on nickel and their change by the action of fluoride have been studied surface analyses such as x‐ray photoelectron spectroscopy (XPS) low energy ion scattering (ISS). The thickness is deduced from height XPS signals , O1s, F1s attenuation covering layers. Argon sputtering gives information in‐depth structure passivating films in combination with higher depth resolution ISS. Their chemical composition electrode potential time exposure to .

Abstract Es werden Untersuchungen über die Bildung kleiner Korrosionslöcher von etwa 1 bis 50 μ Durchmesser an Eisen unter der Wirkung Chlorid‐ und Sulfationen im Phthalatpuffer ( p H = 5) durchgeführt. Eine erhöhte Lochkeimbildung wird mechanisch durch Potentialänderung elektrisch gestörten Passivschichten beobachtet.

The passive film formed by electrochemical oxidation on two different stainless steels differing in molybdenum (Mo) content physiological solution with and without the addition of complexing agent, i.e., citrate, was studied using X-ray photoelectron spectroscopy. alloys were polarized at potentials chamber attached to spectrometer. Thus, composition analyzed spectroscopy prior exposure air (quasi situ). consists predominant oxides, chromium iron oxides. Oxides alloying elements nickel Mo...
Abstract The passivation of nickel has been studied in 1 M NaOH and 0.5 H 2 SO 4 by XPS. An electrochemical specimen preparation transfer to an ultra‐high vacuum, without contact with oxygen, permits a detailed examination the oxide growth potential time resolution. Quantitative evaluation data yields values for thickness partial layers duplex film structure. Ni/NiO/Ni(OH) sequence passive range Ni/NiO/NiOOH transpassive alkaline solutions have confirmed peak analysis, including...
