Porous titanium is used as implant material because of its high specific strength, bone-like stiffness, biocompatibility and good bone cell ingrowth provided that the open pores have sizes between 100 μm and 500μm. Powder metallurgy has been successfully used to produce titanium foams by using the space holder method. Recently, Ti grade 4 has been obtained by powder injection moulding (PIM) of... More

    Summary
    Porous titanium is used as implant material because of its high specific strength, bone-like stiffness, biocompatibility and good bone cell ingrowth provided that the open pores have sizes between 100 μm and 500μm. Powder metallurgy has been successfully used to produce titanium foams by using the space holder method. Recently, Ti grade 4 has been obtained by powder injection moulding (PIM) of titanium hydride, which is cheaper and less reactive than pure titanium. The feasibility of a novel route combining TiH2 and space holders to produce porous titanium is explored in this work.
