Description	W-Se-C coatings were deposited by co-sputtering from WSe2 and C targets. Carbon content varied from 25 at. % up to 70 at. %, Se/W ratio was between 0.9-1.0, with no significant influence of the carbon content on their variations. The hardness of the coatings was evaluated by nanoindentation with values between 3.8 - 5.6 GPa. The structure of the coatings analysed by X-ray diffraction in glancing mode could be defined as quasi-amorphous. The tribological properties were evaluated in a SRV machine using reciprocating ball on disk tests under increasing loads. In general, the friction decreased with increasing loads. The comparison with other transition metal dichalcogenides alloyed with carbon, namely Mo-Se-C and W-S-C systems, showed that W-Se-C coatings could be a good alternative with almost identical friction properties.
