The MoS2/metal (Ti, Mo) nanocomposite coatings were deposited on aluminum alloy substrate by magnetron sputtering. The morphology and microstructure of the coatings were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). The tribological properties of MoS2/metal (Ti, Mo) nanocomposite coatings were investigated using a ball-on-disk tribometer in ambient air. The MoS2/Ti nanocomposite coating showed lower friction coefficient and higher wear resistance as compared to the pure MoS2 coating, which were caused by the microstructure of the composite coating that serve as perfect intermediate lubricants between the contact faces. The effects of metal inclusion in the composite coatings were further discussed combined with the former reports.
