CrMoN/MoS2 coatings with different Mo contents were fabricated by magnetron sputtering technique. The microstructure, mechanical and wear properties at elevated temperatures of coatings were investigated. The
results show that the coating (Mo: 18.5 at.%) exhibited moderate hardness and high adhesion strength, which was primarily due to the effect of solid solution enhancement. Almost all of the Mo added composite coatings demonstrated good wear resistance performance with low wear rates of 10-6 mm3 (N m)-1 magnitude although they had high friction coefficients at RT and 500 °C. Particularly, the coating (Mo: 18.5 at.%) exhibited excellent wear resistance property at 700 °C, which was attributed to the outstanding adhesive strength of coating and lubrication of Cr2O3, MoO2 and MoO3.
