Abstract:
By changing the content of antimony sulfide(Sb2S3) based on the basic formula, the friction materials with different composite were prepared by directly mixed process. The friction and wear test were completed and wear morphology was observed, and the wear mechanism was analyzed. The results show that the tribology properties were obviously improved by antimony sulfide. When the content of antimony sulfide was 4wt%, the stability of friction coefficient, the property of recovery and the wear rate were the best. Compared with the basic formula, the stability of friction coefficient was increased by 10%, and the wear rate was decreased by 22% at 350 ℃. The wear mechanism changed from adhesive wear of without antimony sulfide to slight abrasion wear.
