低侵襲性高力学的生体適合性生体用チタン合金 Titanium Alloys with High Biological and Mechanical Biocompatibility
β-type titanium alloys composed of non-toxic and allergy-free elements with low modulus are getting much attention for biomedical applications. The author has developed Ti-29Nb-13Ta-4.6Zr (TNTZ) where Nb, Ta, and Zr are non-toxic and allergy-free are elements showing low Young's modulus. Focusing on TNTZ, biological and mechanical biocompatibility including fatigue characteristics, fretting fatigue characteristics, and wear characteristics, functionalities such as super elastic and shape memory effect, and bioactive surface modification of low modulus titanium alloys with high biological and mechanical biocompatibility for biomedical applications are described.
