Abstract
The present invention is a medical implant or device fabricated, in any manner, from a niobium (Nb)—titanium (Ti)—zirconium (Zr)—Molybdenum (Mo) alloy (NbTiZrMo alloy). The implant or device has components at least partially fabricated from a metal alloy comprising a) between about 29 and 70 weight percent Nb; b) between about 10 and 46 weight percent Zr; c) between about 3 and 15 weight percent Mo; and a balance of titanium. The inventive alloy provides for a uniform beta structure which is corrosion resistant, and can be readily processed to develop high-strength and low-modulus, with the ability for conversion oxidation or nitridization surface hardening of the medical implant or device.
Claims17
A medical implant or deve fabricated from a niobium (Nb)—titanium (Ti)—zirconium (Zr)—Molybdenum (Mo) alloy (NbTiZrMo alloy), said medical implant or device comprising:
- components at least partially fabricated from a metal alloy consisting of:
- (a) between about 29 and 70 weight percent Nb
- (b) between about 10 and 46 weight percent Zr
- (c) between about 3 and 15 weight percent Mo
- (d) and a balance of titanium;
- wherein no other alloy exceeds the amount of Nb, and the alloy provides for a uniform beta structure which is uniform and corrosion resisting, and is capable of being readily processed to develop high-strength and low-modulus, with the ability for conversion oxidation or nitridization surface hardening of the medical implant or device.
A niobium (Nb)—titanium (Ti)—zirconium (Zr)—molybdenum (Mo) alloy (NbTiZrMo alloy), consisting of:
- (a) between about 29 and 70 weight pent Nb
- (b) between about 10 and 46 weight percent Zr
- (c) between about 3 and 15 weight percent Mo
- (d) up to about 3 wt. % of one or more contaminant elements each selected from the group consisting of Si P, Cu, F, Ta, Hf, Sn and Pd, up to about 1 wt % each;
- and
- (e) a balance of titanium;
- wherein no other alloy constituent excoedis the amount of Nb.
