The invention relates to a titanium-based metal glass/hydroxyapatite composite material and a preparation method thereof. The composite material consists of titanium-based metal glass and hydroxyapatite in a mass ratio. The preparation method comprises the following processes of: weighing pure metals Ti, Zr, Cu and Pd according to the atomic ratio of elements in the titanium-based metal glass components, and smelting the pure metals into a titanium-based metal glass master alloy; melting the titanium-based metal glass master alloy in an atomic gas atomization device, then performing high-speed ejection and granulation, mixing the titanium-based metal glass powder and the hydroxyapatite powder in a mass ratio after grading, pressing the mixture into a blank, and sintering the blank in an electric spark sintering device to obtain the titanium-based metal glass/hydroxyapatite composite material. The method has the advantages of low temperature and quickness because the electric spark device is adopted in the sintering process; and the prepared composite material has low elastic modulus and good biological and mechanical properties of recoverable strain and biocompatibility.
