Abstract

FFC process could be used to prepare titanium foams. The mixed oxides CaO-TiO₂ with mole ratio 1:2 were sintered into CaTiO₃-TiO₂ mixture. CaTiO₃-TiO₂ was then used as cathode and electrolyzed in molten CaCl₂ to prepare porous titanium. The porous titanium with the porosity of about 72.15% was first fabricated. The internal pores are in the presence of circular cavities and the pore size is in the range of 50–100 μm. Compared with the powder metallurgy technique using the space-holder this method promises to be lower cost and less processing. It is potential to fabricate titanium foams using FFC process.
