“…After sputter cleaning, the V2p 3/2 and V2p 1/2 maxima are shifted to 513.25 and 520.85 eV, respectively, consistent with the reported values for both VC 1Àx (Choi, 1999;Liao et al, 2005) and VN (Sanjiné s et al, 1998;Liao et al, 2004;Glaser et al, 2007). The peak at about 513 eV is already observed before sputter cleaning, but with a much lower intensity.…”

V-Al-C-N hard coatings with high carbon content were deposited by reactive radio-frequency magnetron sputtering using an experimental combinatorial approach, deposition from a segmented sputter target. The compositiondependent coexisting phases within the coating were analysed using the complementary methods of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), X-ray absorption near-edge spectroscopy (XANES) and extended X-ray absorption fine-structure spectroscopy (EXAFS). For the analysis of the X-ray absorption near-edge spectra, a new approach for evaluation of the pre-edge peak was developed, taking into account the selfabsorption effects in thin films. Within the studied composition range, a mixed face-centred cubic (V,Al)(C,N) phase coexisting with a C-C-containing phase was observed. No indication of hexagonal (V,Al)(N,C) was found. The example of V-Al-C-N demonstrates how important a combination of complementary methods is for the detection of coexisting phases in complex multi-element coatings.

Self-cleansing of transition metal nitrides is discovered to take place during ultra-high vacuum annealing of TiN, NbN, and VN thin films. Native oxide layers from air exposure disappear after isothermal anneal at 1000 degrees C. Also, for TiN, the Ti 2p and N 1s X-ray photoelectron spectra (XPS) recorded after the anneal are identical to those obtained from in-situ grown and analyzed epitaxial TiN(001). These unexpected effects are explained by oxide decomposition in combination with N-replenishing of the nitride during recrystallization. The finding opens up new possibilities for true bonding assignments through non-destructive XPS analyses, thus avoiding artefacts from Ar etching. (C) 2016 Author(s).

Among these elements, particular attention has been given to the vanadium-containing coatings (Magnéli phases V n O 2n−1 ), which showed interesting tribological properties in the temperature range 500-700•C [2,[10][11][12][13][14][15]. Dissimilar series of V-based hard coatings have been developed, such as ternary…”
