摘要	To improve the fretting wear resistance of TC4 titanium alloy, DLC films were deposited on TC4 titanium alloy by unbalanced magnetron sputtering technology. The fretting wear behavior of DLC film and TC4 titanium alloy were comparatively investigated in a condition of dry friction, which reveals the mechanism of DLC film on the fretting wear resistance. The surface morphology, phase composition and nano-hardness of the films were analyzed by atomic force microscope, Raman spectroscopy and Nanoindentation tester. The fretting friction and wear performance of DLC film or TC4 alloy was studied by SRV-V fretting friction tester with a ball/plane contact configuration. The wear tracks of the materials were characterized by laser confocal microscope and field emission scanning electron microscope with DES analysis. The fretting damage mechanism was revealed by the analysis of Ft-D-N curve, three-dimensional profile, wear morphology and wear chemical composition. Compared with TC4 alloy, the DLC film exhibited very low friction coefficient and wear volume. At a normal load of 10 N, friction coefficient of the DLC film ranged between 0.01~0.03 while that of TC4 substrate ranged between 0.07~0.12. The wear rate of TC4 titanium alloy increased with increased displacement amplitude. In contrast, the wear rate of DLC film decreased with increased displacement amplitude. Under the displacement amplitude of 100 µm, the wear rate of the TC4 alloy was largest as 5.02×10-5 mm3/(Nm), while that of the DLC film was the lowest as 6.70×10-8 mm3/(Nm). The wear of TC4 alloy was serious and the wear mechanism is adhesive wear, abrasive wear, fatigue peeling and oxidative wear, accompanied by plastic deformation, while the wear of DLC film was slight and the wear mechanism is dominated by abrasive wear. It can be concluded that DLC film has higher hardness and good lubricating properties. Under dry friction conditions, the DLC film can effectively improve the fretting wear resistance of TC4 alloy. © 2021, Chongqing Wujiu Periodicals Press. All rights reserved.
