| Abstract: |
| The work aims to improve loose structure, hardness, friction and wear properties of MoS2 films. MoS2-Zr composite films with different Zr content were deposited on GCr15 substrate by ion assisted magnetron sputtering technology. Morphology of surface and cross section of films was analyzed by SEM; composition was determined by EDS; hardness by Micro Vickers tester; indentation test was performed by Rockwell-C hardness tester; friction and wear properties of the films were evaluated by ball-disk rotating friction and wear tester. The compactness and hardness of MoS2-Zr composite films increased with the increase of Zr content with hardness value ranging from 300~500HV. The adhesion strength between composite film and substrate increased with the increase of Zr content and decreased in case of excessive Zr content. The MoS2-Zr composite films with 15 at.% Zr content showed the best tribological properties, their average friction coefficient was 0.09, wear rate 9.33×107 mm3•N–1•m–1 and wear life 5.25×105 r. Loose structure, hardness and adhesion strength of MoS2-Zr composite films were improved. Lower friction coefficient and longer wearing life can be obtained provided with appropriate Zr doping content. |
