A study of amorphous Ti–Ni alloys by X-ray photoelectron spectroscopy

Investigation on mechanical properties of sputtered TiNi thin films

“…Usually, TiNi films prepared at room temperature are amorphous [4,5], in order to crystallize the TiNi films [6], the as- The microstructures of thin films are studied by the X-ray diffractometer with Cu K␣ radiation of 0.154 nm, work voltage: 35 kV; electrical current: 40 mA; scanning rate: 0.02 • . The mechanical properties are studied by MTS IIXP Nano-Hardness Tester, with a three-sided pyramidal Berkovich diamond indenter.…”

Comparison of intrinsic zero-energy loss and Shirley-type background corrected profiles of XPS spectra for quantitative surface analysis: Study of Cr, Mn and Fe oxides

“…Some authors have said that the difference between the Shirley and Tougaard backgrounds in the core level peaks when normalized with respect to the elemental values is the intrinsic energy loss part, and then that the difference provides the information on the density of the states at the Fermi level [33,34]. On the other hand, Végh has claimed that this occurs because the Shirley background corrected spectra involve the intrinsic energy loss part [35,36].…”

XPS study on surface modification of NiTi alloy by acidic solution immersion and subsequent heating in air

“…In the Ti 2p region, two intense peaks with symmetric shapes were found at 459.1 and 464.7 eV, which corresponded to the TiO 2 state's 2p 3/2 and 2p 1/2 peaks (Figure 2C). 23 Small peaks at 454.3 eV, corresponding to metallic Ti, were also detected on the surfaces immersed in aqueous solutions of HNO 3 and H 2 SO 4 20 . The N 1s spectra comprised two peaks (Figure 2D); the intense peak at 397.1 eV and the weak peak at 400.1 eV were assigned as nitride and N bonded to O (i.e., N–O), respectively 24,25 .…”

“…The TOA was 90° as a regular analysis mode. In the Ni 2p 3/2 region, an intense peak at 852.9 eV was a metallic Ni state 20 . Additionally, a small broad peak at ~856 eV and a tiny satellite peak at ~862 eV were found on the untreated and water‐immersed surfaces.…”
