“…1, is positioned at 46.9 eV, and cannot be described reliably by a fit procedure due to the presence of multiple overlapping peaks from the spin-orbit and multiplet splitting typical for 3d transition metals [20,[36][37][38]. The position of the main peak is commensurate with either Mn or Mn-silicides, or a mixture of both.…”

“…A second approach is the formalism of Tougaard [14], which relies on rigorous modeling of extrinsic losses due to inelastic scattering of electrons associated with their transport through the solid. Recently, by comparison of intrinsic zero-energy loss and Shirleytype background corrected spectra of iron oxides, Oku et al [15] demonstrated the validity of Shirley background use. In the present investigations, Shirley background was subtracted from each spectrum before the peak fitting.…”

Transition metal dichalcogenides belong to one of the most developed class of materials for solid lubrication. However, one of the main drawbacks of most of the self-lubricating coatings is their low load-bearing capacity, particularly in terrestrial atmospheres. In our previous works, alloying thin films based on tungsten disulfide with non-metallic interstitial elements, such as carbon or nitrogen, has been studied in order to improve tribological performance in different environments.Excellent results were reached with the deposited coatings hardness, in some cases, more than one order of magnitude higher than single W-S films. 2In this work, W-S-C films were deposited with increasing Cr contents by co-sputtering chromium and composite WS 2 -C and targets. Two films were prepared with approx. 7 and 13 at.% of Cr.Alloying with chromium led to dense films with amorphous microstructure; the hardness and adhesion was improved. Sliding tests were carried out in dry and humid air using pin-on-disc with 100Cr6 steel ball as a counterpart. To analyse the sliding process, the surfaces in the contact were investigated by X-ray photoelectron spectroscopy (bonding), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Raman spectroscopy (TEM). Surface and sub-surface structural modification of the coating and composition of the transferred tribolayer are discussed in detail. High friction in humid air was attributed to the absence of well-ordered WS 2 sliding interface. On the other hand, the existence of such interface explained a very low friction observed in dry air.
