1. the preparation method of a porous titanium copper calcium material, it is characterised in that processing step is as follows:

  • (1) by Ti85~

    97%, Cu1~

    5%, Ca2~

    10% mass percent, weigh Ti, Cu, Ca powder respectively, powder is put into ball grinder carries out mechanical alloying, evacuation then ball milling 50 ~ 100h after sealing with anhydrous alcohol, gained Ti-Cu-Ca alloying powder is still placed in anhydrous alcohol, standby;

    (2) by the Ti-Cu-Ca alloying powder obtained in step (1) and NH4HCO3Powder mixes 120 ~ 240min in batch mixer and obtains mixed-powder;

    In mixed-powder, the mass percent of Ti-Cu-Ca alloying powder is 95% ~ 75%, NH4HCO3The mass percent of powder is 5% ~ 25%;

    (3) mixed-powder step (2) obtained loads stainless steel mould, cold moudling under the individual event pressure of 200 ~ 500MPa, obtains block pressed compact after moving back mould;

    (4) block pressed compact step (3) obtained loads in graphite jig, insert in discharge plasma sintering stove again, system vacuum is sintered after being evacuated to 2 ~ 6Pa, heating rate is 50 ~ 100min/ DEG C, at 800~

    1000 DEG C be incubated 5~

    10min, cool to the furnace room temperature porous titanium copper calcium medical material.
