Structure and tribological properties of MoCN-Ag coatings in the temperature range of 25-700 °C

► MoCN-Ag nanocomposite coatings for tribological applications. ► Low friction coefficients in the temperature ranges of 25-100 °C and 400-700 °C. ► Carbon phase improves tribological properties at low temperatures. ► Ag, MoOx and AgMoxOy phases serve as lubricants above 400 °C.
