主 题：Porous scaffolds Titanium Powder metallurgy Space holder Graded porosity
摘 要：To optimize both the mechanical and biological properties of titanium for biomedical implants,a highly flexible powder metallurgy approach is proposed to generate porous scaffolds with graded porosities and pore *** pellets acting as space holders were compacted with titanium powder and then removed by dissolution in water before *** morphology,pore structure,porosity and pore interconnectivity were observed by optical microscopy and *** results show that the porous titanium has porosity levels and pore size gradients consistent with their design with gradual and smooth transitions at the interfaces between regions of differing porosities and/or pore ***,the porous titanium has high interconnectivity between pores and highly spherical pore *** this article we show that this powder metallurgy processing technique,employing the novel sugar pellets as space-holders,can generate porous titanium foams with well-controlled graded porosities and pore *** method has excellent potential for producing porous titanium structures for hard tissue engineering applications.
