  ABSTRACT: In this paper, the sliding contact fatigue wear performance of shot-peened zirconia-silicon carbide composite (ZrO2/SiC) plates in contact with silicon nitride balls under compressive residual stress in dry conditions was investigated in order to improve the wear resistance of ZrO2/SiC friction parts. The wear resistance of ZrO2/SiC plates after shot peening was higher than that of plates not treated with shot peening in sliding wear testing under Hertziancontact. Due to fine Zirconia particle shot peening, the tetragonal phase crystal structure in ZrO2 in the near-surface of ZrO2/SiC plates was changed, and 1100 MPa compressive residual stress could be introduced into the near-surface layer of ZrO2/SiC plates. The compressive residual stress was determined to be the main factor in the improvement of the sliding wear resistance of ZrO2/SiC plates.
