Effect of space holders on fabrication of porous titanium alloy-hydroxyapatite composite through powder injection molding

Powder injection molding (PIM) is able to produce porous titanium alloy/hydroxyapatite composite through the space holder technique. Thermal debinding and sintering processes were the main challenges due to different properties of metal and ceramic in producing such composite. This study focused on...
