Spark Plasma Sintering of Titanium Alloys for Biomedical Applications

Abstract:

A dense Ti6Al4V with a porous cp2-Ti surface layer was produced by Spark Plasma Sintering, using a Calcium Phosphate powder as space holder. The duplex porosity structure resulting from the space holder (large pores) and the uncompleted densification of the titanium powder (micrometric pores) has a very positive effect on both cell in-growth and cell proliferation.The porous structure decreases the fatigue resistance significantly, even if less than what reported in literature, likely due to the formation of a globular microstructure in the interface region of the substrate, where fatigue crack nucleation occurs. The porous surfaced specimens succeeded the adhesion by pull-off test, the resistance to static and cyclic shear stresses and the Taber abrasion test.
