In this paper, we report a machinable Ti3SiC2/hydroxyapatite (HAp) composite prepared by spark plasma sintering. The experimental results of a drilling test demonstrated that the composites exhibit excellent machinability when the Ti3SiC2 content is higher than 20 vol%, which can be attributed to the improvement in the mechanical and machinable properties of the composites by addition of Ti3SiC2 phase, which possessess unique mechanical and machinable properties and energy-absorbing mechanisms. The superior mechanical and machinable properties of Ti3SiC2/HAp composites suggest that the composite system could be attractive for practical applications of novel biomaterials.
