泡沫浸渍法制备小梁金属及性能
Fabrication of trabecular metal via impregnation and its properties
摘要
Abstract
Trabecular metal (Porous tantalum) was prepared by dipping with polymer foams, using worked PU foam as template, which had a high intension and was compatible with the elastic modulus of human bone. The density, micro-morphology, hole structure and impurity content were analyzed by fluid statics, SEM and EDS. The results show that the specimens can be obtained with the density of 6.06-7.02 g/cm3, the porosity of 57.7%-63.5% and the pore size of 313-622 μm, which have a similar three-dimensional connected hole morphology to cancellous bone, and with no other elements on the sample. The mechanical performance shows that the compressive strength is 50-73 MPa and the elastic modulus is 1.73-2.72 GPa, both similar to cancellous bone.关键词
