摘要：
The increase in usage of prosthesis in patients has revealed evidence of in vivo fretting-assisted crevice corrosion of the mating surfaces, stress induced corrosion and fatigue failure, which lead to revision and bone loss every time surgery is performed. Titanium based alloys for the new generations of implant materials necessitate high strength-to-weight ratio, enhanced corrosion resistance, superior biocompatibility and excellent mechanical properties. Ti-13Mo-7Zr-3Fe (TMZF) and Ti-13Mo-13Nb-3Fe (TMNF) quaternary alloys address the aforementioned properties. The corrosion behavior, wettability, roughness and morphology of the alloys are determined in an effort to access their biocompatibility. The Modulus of elasticity and hardness of the alloys are measured by a nano-indenter.
