Comparative Study of the Tribological Behaviour of Self-Lubricating W-S-C
Original language description
In this paper, the general comparison between W-S-C and Mo-Se-C coatings is presented. The main effort is pointed on the tribological behaviour of both systems when tested by pin-on-disk against steel counterpart balls under different testing conditions:applied normal loads, temperatures and relative humidity of the atmospheres. Both coatings were deposited by co-sputtering from a C target with a varying number of TMD pellets which could lead to C contents in the films in the range from 30 at.% up to 70 at.%. A Ti interlayer was interposed between the films and the substrates for improving the adhesion. Typically, W-S-C films are harder than Mo-Se-C films. From the tribological point of view, W-S-C films are more thermal stable than Mo-Se-C films although the friction coefficients of these last ones are lower when tested in humid containing atmospheres.
