Synthesis and Structural Properties of Mo-Se-C Sputtered Coatings

Popis výsledku v původním jazyce

Mo-Se-C coatings were prepared by non-reactive r.f. magnetron sputtering from carbon target with embedded MoSe2 pellets. The carbon content and Se/Mo ratio determined by electron probe microanalysis increased from 29 to 68 at.% and from 1.7 to 2.0, respectively, as a function of the decreasing number of pellets. The coating structure analyzed by X-Ray diffraction, Raman spectroscopy and X-ray photoelectron spectroscopy showed that Mo-Se-C was a mixture of amorphous carbon and Mo-Se phases, since no traces of molybdenum carbides were observed. Linear increase of the hardness from 0.7 (29 at.% C) to 4.1 GPa (68 at.% C) showed a significant improvement compared to values typical for pure MoSe2 coating.
