Abstract :

Increasing biocompatibility of implant materials is an important factor in developing better and long-lasting implants that function in a very close manner to actual tissue and bone. Various alloys have been used due to their biocompatibility, such as: stainless steels, titanium based alloys and nickel or cobalt alloys. Depending on the alloying elements used it is possible to modify the material properties to fit into various niches of use such as pacemaker devices, stents, biosensors, dental or bone implants and others. Some alloying elements show higher biocompatibility than others and the commonly used alloys include elements that can be detrimental to human health such as Nickel, Vanadium and Cobalt. Using materials such as Nb, Fe and Zr in order to replace the commonly used metals reduces the risks of accumulation of various substances that can damage tissue and lead to health complications. The proposed alloys are elaborated in a Five Celles levitation melting furnace under argon atmosphere in order to create a more homogeneous material with reduced defects and inclusions. The cast alloys are then analyzed through modern methods such as SEM, XRD, EDS and their mechanical properties such as hardness and strength and these properties are compared to that of bone in order to determine mechanical reliability.
