In order to extend the service life of the wear resistant layer of resin-based devices， a Ti-DLC-MoS2 composite film layer was developed.The resin-based materials were sequentially coated by magnetron sputtering， and the effects of different coating processes were investigated.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 coating； 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 significantly enhanced the wear resistance of resin-based devices， resulting in a substantial improvement in their service life.
