抄録

In order to develop new titanium matrix composite for surface-coating titanium used in biomedical field, magnesia particles were added into pure titanium through hot press sintering method. Samples fabricated at the temperature of 973 K and at the pressure of 55 MPa were used to investigate the effects of magnesia addition on the properties of the new composite. In the fabricated samples, uniform dispersion of magnesia particles in titanium matrix was successfully obtained and no reaction layer was observed at interface between magnesia particles and titanium matrix. The volume fraction (<I>V</I><SUB>f</SUB>) and the size of magnesia particles mainly influenced tensile strength of the samples. When the size of magnesia particles was in the range of 25–90 \\micron, tensile strength of the composite was increased with increase of <I>V</I><SUB>f</SUB> till 5%. With respect to biocompatible property, the results of simulated body fluid immersion test showed that an apatite surface layer was formed on the fabricated magnesia/titanium composite samples, which would be benefit to bonding of the material to surrounding bone when it would be implanted into human body.
