Abstract

TiB_2P/Al composite was successfully fabricated by squeeze casting technology. Its mechanical and tribological properties were evaluated. The elimination of Ti-Al intermetallic compound was confirmed by X-ray diffraction (XRD) studies. At 45% volume fraction, the bending strength at ambient temperature was 934 MPa. And the fracture modes included ductile failure of Al matrix and brittle fracture of TiB₂ particles. In dry sliding wear mode, severe plastic deformation and adhesive wear were found on the worn surfaces of the SiC_P/Al composite. But no obvious characteristics of adhesion or abrasion wear were observed on that of the TiB_2P/Al composites. At the steady stage, the friction coefficient of the SiC_2P/Al composite was about 0.6. While that of TiB_2P/Al composite was only about 0.16-0.17.
