Abstract

Abstract

Electrolytic titanium powder was utilized as the raw material for fabricating porous titanium through press-sintering technique. The forming and sintering characteristics were investigated. Then the mechanical properties, pore structure, pore size distribution and permeability of the prepared porous titanium were characterized. The results show that with the increase of pressing pressure, the bridging space between the particles of electrolytic titanium powder with secondary particle characteristics gradually disappears. Porous titanium powder with different porosity and mechanical strength can be obtained by adjusting the molding pressure and sintering temperature. Compared to HDH titanium powder, electrolytic titanium powder exhibits better molding performance, easier sintering densification, higher porosity, greater permeability, and a higher Young’s modulus. A porous titanium was obtained by using electrolytic titanium powder with a particle size of 74~104 μm at 70~110 MPa and then sintering it at 1110 ℃, whose Young’s modulus is similar to that of human cancellous bone. The permeability and maximum pore diameter meet the requirements of TG035 and TG020 in the standard for sintered metal filtration elements (GBT6887-2019), indicating promising applications in the fields of human cancellous bone implants and filtration materials.
