Method using laser quick forming producing HA/Ti gradient biological activity material

The invention discloses a method for preparing a HA/Ti gradient biological activity material by adopting laser rapid forming. The method introduces the conception of gradient function material, changes the mixture ratio of CaHPO4*2H2O+CaCO3 and titanium powder in a gradient way, and adopts the laser rapid forming technology to melt and cover the mixing material into the surface of titanium metal directly in hope of obtaining the medical gradient biological activity material with good bonding strength, thereby improving the proliferation and differentiation of the osteocyle on the metal surface, solving the difficulty of the early bonding between the metal implantation material and the bone, and providing a theoretical and experimental basis for better clinic application of titanium.
