| Abstract: |
| The work aims to enhance lubrication properties of MoS2 films in high temperature environment. Co-sputtering MoS2 and Al targets were used to deposit MoS2-Al composite films by adopting unbalanced magnetron sputtering. Surface, sectional morphology, microstructure, mechanical property and tribological property in high temperature environment of the MoS2-Al composite films was evaluated with field emission scanning electron microscope (SEM), X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), nano indenter and CSM high temperature friction and wear tester, respectively. Morphology of grinding cracks and spots was observed with Olympus microscope. When the temperature exceeded 400 ℃, the MoS2-Al composite films with Al content of 18.3 at.% exhibited excellent lubrication property at high temperature, friction coefficient maintained at nearly 0.07, and average friction coefficient was 0.172, which decreased by 64% compared with that of pure MoS2 films. Friction curve of the composite films was steady. The optimum amount of Al in the film is 18.3%, the addition of Al has the effect of preferential oxidation while preserving the MoS2 structure, thus protecting the MoS2 structure from being destroyed, and significantly enhancing lubrication capacity of MoS2-Al composite films in high temperature environment. |
