    Abstract

    CaSiO3/Ti3SiC2 composites with different Ti3SiC2 volume fractions were fabricated by spark plasma sintering. The mechanical properties and hydroxyapatite formation ability in simulated body fluid were investigated. The results showed that no reaction occurred between the CaSiO3 and Ti3SiC2, and mechanical properties were improved significantly with the increase of the Ti3SiC2 volume fraction. Bending strength and fracture toughness reached 271 ± 12MPa and 2.47 ± 0.17 MPa·m 1/2 respectively, with the addition of 30vol% Ti3SiC 2. However, bioactivity is reduced due to the presence of large amount of Ti3SiC2. In order to retain the enough bioaetivity, the Ti3SiC2 volume fraction should not be above 30%.
