Abstract
Disclosed is a method for preparing a heterogeneous metal composite structure for medical implantation, including the steps of: step 1, preparing titanium alloy powder into a porous skeleton according to different printing strategies; step 2, filling magnesium after being melted into pores of the porous skeleton; and step 3, cooling a titanium-magnesium interpenetrating phase composite structure prepared in step 2 to room temperature, and covering a surface of the titanium-magnesium interpenetrating phase composite structure with a hydroxyapatite coating. In the present disclosure, a porous lattice dot-array structure of titanium alloy is used as a skeleton, and the skeleton pore is filled by pressureless infiltration of magnesium or hot isostatic pressure.
