Production of Titanium Based Porous TiNb Alloy for Biomedical Applications

In recent years, intensive studies have been carried out on the production and application of titanium-based alloys as porous implant materials in order to promote the use of titanium-based alloys as biomolecules. Ti-based alloys are widely used in medical applications due to their high corrosion resistance, low elastic modulus and superior biocompatibility. Such alloys are especially preferred as hard tissue implants. When the alloy is produced as a porous material it is essential that it will allow the passage of live tissue through the body, allowing blood and nutrient transport, and a good bond with the bone. For this reason, pure titanium and titanium-based Ti-10Nb alloy was produced in this work using high purity elemental powders. After the production, the pure titanium structure consisted entirely of α phase, while in the structure of the Ti-10Nb alloy, β and α" phases were detected in addition to α phase. It was determined that the porosity ratio of Ti-10Nb alloy is higher than that of pure titanium specimen and the elastic modulus is closer to bone structure. It was understood that Ti-10Nb specimen produced would be more suitable as an ideal implant material in terms of microstructure and compressive strength
