Abstract EN
Increased durability of permanent TiAl6V4 implants still remains a requirement for the patient’s well-being.
One way to achieve a better bone-material connection is to enable bone “ingrowth” into the implant.
Therefore, a new porous TiAl6V4 material was produced via metal injection moulding (MIM).
Specimens with four different porosities were produced using gas-atomised spherical TiAl6V4 with different powder particle diameters, namely, “Small” (<45 μm), “Medium” (45–63 μm), “Mix” (90% 125–180 μm + 10% <45 μm), and “Large” (125–180 μm).
Tensile tests, compression tests, and resonant ultrasound spectroscopy (RUS) were used to analyse mechanical properties.
These tests revealed an increasing Young’s modulus with decreasing porosity; that is, “Large” and “Mix” exhibit mechanical properties closer to bone than to bulk material.
By applying X-ray tomography (3D volume) and optical metallographic methods (2D volume and dimensions) the pores were dissected.
The pore analysis of the “Mix” and “Large” samples showed pore volumes between 29% and 34%, respectively, with pore diameters ranging up to 175 μm and even above 200 μm for “Large.” Material cytotoxicity on bone cell lines (SaOs-2 and MG-63) and primary cells (human bone-derived cells, HBDC) was studied by MTT assays and highlighted an increasing viability with higher porosity.
