| Abstract: |
| To explore the effect of different oxidation treatments on the wear resistance of MoS2 solid lubrication film prepared by magnetron sputtering. Before sputtering the MoS2 film, the aluminum alloy was pre-treated by anodic oxidation, micro arc oxidation and hard oxidation, and then a layer of MoS2 lubrication film was deposited on the surface by sputtering. The wear resistance of the film was evaluated by friction and wear test, and analyze the surface morphology, structure and wear scar morphology and composition of the film by SEM, XRD, EDS. The XRD pattern shows that aluminum alloys treated with different oxidation methods will not affect the structure of the MoS2 film. The surface of MoS2 film on aluminum alloy was prepared by sulfuric acid anodizing and magnetron sputtering is the most compact, uniform, low roughness, cauliflower like. The cross-section SEM photos show that the sputtering film and the substrate are closely combined, The thickness of the sputtered film is 2 μm, The friction coefficient of the samples is less than 0.1 and the wear life was more than 450 000 r, 300 000 r and 90 000 r respectively under high loads of 10, 20, 30 N, which were all higher than other samples. All film samples have excellent environmental resistance to humidity and heat. In the process of friction, the load borne by the sample is basically transferred to the oxide film. After anodizing, the surface roughness of the coated sample is small, which will not produce large adhesive wear as the tangential stress is small, so the wear loss speed is slow and the wear life is long. Therefore, the anodic oxidation pretreatment of aluminum alloy has the best effect on improving the friction resistance of sputtering MoS2 film. |
