“…In XAS analysis, the detection technique, either electrons (total electron yield) or photons (fluorescence yield), provides information on the chemical structure at different sample depths. In order to identify the chemical nature of tribofilm species, the obtained spectra are compared with the spectra of different model compounds with known chemistry [12,25,[27][28][29][30][31][32][33]. To enable non-vacuum environment analysis, hard X-rays are required.…”

Chemical characterisation of boundary lubricated interfaces is essential for developing mechanistic models that describe lubricant additive interactions with the surface and their effect on tribological performance. In this study the potential for using the synchrotron-based reflection mode X-ray absorption spectroscopy (XAS) technique for in-situ chemical characterisation of lubricant films has been studied.

Abstract:The modification of tribological properties of highly loaded components by selecting a suitable manufacturing process is state-of-the-art. Beyond the generation of microgeometrical structures, the present study investigates the potential of chemical alterations, i.e., metalworking fluid additives engaged in a grinding process to improve the chemical surface properties of machined gear synchronizations. These gearbox components ensure a uniform switching operation by harmonizing the number of revolutions between the power transmitting components by friction. A short running-in phase and a friction coefficient which is constant over the entire duration of use are required. The results show that the addition of polysulfide as well as zincdialkyldithiophosphate in the metalworking fluid could considerably reduce the friction coefficient fluctuations and the running-in phase of the generated synchronizations in later operation tests. The wear distances were lower although the machined parts revealed higher surface roughnesses as the reference workpieces, which indicates the formation of sorption or reaction layers of the additives with the metal surface.

“…In fact, many instrumental techniques of material characterization and surface analysis have been used in tribofilm characterisation, as shown in Table 1. Readers interested in this issue can read more in literatures [11,[12][13][14][15][16] .…”
