Inspite of superior mechanical properties such as low modulus of elasticity, high strength to weight ratio and excellent biocompatibility among the biomedical titanium alloys, it suffers from poor wear resistance. The objective of this work is to enhance the wear resistance of the newly developed beta titanium alloy, gum metal (Ti-23Nb-0. 7Ta-2Zr-10) by subjecting it to various heat treatments. These alloys were subjected to α and β Solution treatments and its mechanical properties were measured. Phase analysis was performed using X-ray diffraction technique and microstructural observations were made using scanning electron microscopy. The sliding wear behavior of all these heat treated samples were studied under simulated body fluid (Hank's solution) condition and compared with the β Cez alloy. The results of the above studies will he discussed in detail in this paper. Source
