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.
