Zirconia toughened alumina(ZTA) ceramic particles reinforced high chromium cast iron (HCCI) architecture composite has excellent wear resistance.However,as the cast composite is difficult to process and easy to fracture,a heat treatment is required.The heat treatment of ZTA/HCCI configuration composite was carried out,the microstructure of the composite before and after quenching was analyzed,and the effect on the wear resistance of quenched and quenched-tempered heat treatment for ZTA/HCCI architecture composites was investigated.The results show that the matrix microstructure of HCCI is martensite or tempered martensite after heat treatment,which ensures the metal matrix also has relatively wear resistance.Compared with the quenched-tempered HCCI,the wear mass loss of quenched and quenched-tempered ZTA/HCCI composites reduces by 53% and 55%,respectively,which means the wear resistance of composites is promoted.The worn surface structure of the ZTA/HCCI architecture composites reveals that ZTA ceramic particles have a shadow effect to enhance the wear resistance of HCCI.
