Tribological Properties of MoS2-Ti Films Sliding Against Different Mating Materials in Dry Sliding
In order to study the tribological behavior of MoS2-Ti thin films sliding against 9Cr18 steel,W-DLC and DLC thin films,MoS2-Ti,W-DLC and DLC films are deposited on 9Cr18 steel by magnetron sputtering and plasma enhanced chemical vapor deposition technology respetively.The morphology,composition and phase structure of the films are charac-terized by SEM,EDS and XRD.The hardness and tribological properties of MoS2-Ti films sliding against 9Cr18 steel,W-DLC and DLC are investigated by hardness tester and ball-on-disc tribometer respectively.The results show that the MoS2-Ti films sliding against DLC have the lowest friction coefficient and wear rate among these three mating materials.Compared to the MoS2-Ti films sliding against the 9Cr18 ball,MoS2-Ti films and W-DLC film does not reduce the friction coefficient and wear rate.The wear mechanism of MoS2-Ti films and W-DLC is adhesive wear and abrasive wear,while the wear mecha-nism of MoS2-Ti films and DLC is adhesive wear.
