Study on Modification of Wear Resistant Layer on Resin-Based Devices by MoS2
In order to extend the service life of the wear resistant layer of resin-based devices,a Ti-DLC-MoS2 composite film layer was devel-oped.The resin-based materials were sequentially coated by magnetron sputtering,and the effects of different coating processes were investiga-ted.Results showed that the wear resistance of the Ti-DLC-MoS2 composite film was improved by 30%compared to that of the Ti-DLC mixed film.In comparison with the resin material without a film layer,the wear resistance of the Ti-DLC-MoS2 composite film layer was enhanced by 54%.The friction coefficient of the composite film was the lowest,which was 0.077 6,under specific conditions:a cavity pressure of 3.00 Pa and power density of 0.30 W/cm2 for sputtering the Ti coating;a cavity pressure of 0.65 Pa and power density of 4.00 W/cm2 for the DLC coat-ing;and a cavity pressure of 3.00 Pa and power density of 7.00 W/cm2 for the MoS2 coating.The Ti-DLC-MoS2 composite film layer signifi-cantly enhanced the wear resistance of resin-based devices,resulting in a substantial improvement in their service life.
