Synthesis, microstructure and mechanical properties of W-S-C self-lubricant thin films deposited by magnetron sputtering

Popis výsledku v původním jazyce

W-S-C thin films were deposited by magnetron sputtering in a semi-industrial deposition unit. Various parameters like the composition, crystallinity, morphology and hardness were studied. A single coating was selected for tribological studies in different testing environments. The tribological response during ambient air testing was governed mainly by carbon-based phase at low normal loads and both carbon-based and WS2 rich tribofilms at higher loads. Very low coefficients of friction (similar to 0.01) were obtained during testing at elevated temperature due to accelerated formation of WS2 rich tribofilms. The tribological response in a vacuum against a steel-based counterbody was unsatisfactory due to the presence of a carbon-phase at the sliding interface. Discrepancies were observed between the tribological response in dry N-2 and vacuum environments.
