Claims15
A magnesium-based bulk metallic glass composite, which is a single material including a magnesium-based material and a TiZr alloy, wherein a particle size of the TiZr alloy is in a range from 25 μm to 45 μm.
A suture anchor, comprising:
- an anchor body having a proximal end and a distal end, wherein a thread having a plurality of turns is disposed on an outer surface of the anchor body, a transverse eyelet is disposed near the distal end, and a plurality of suture channels are disposed on the outer surface of the anchor body;
- wherein the suture anchor is made from a magnesium-based bulk metallic glass composite which is a single material including a magnesium-based material and a TiZr alloy, and a particle size of the TiZr alloy is in a range from 25 μm to 45 μm.
A method for preparing a magnesium-based bulk metallic glass composite, comprising steps of:
- (a) providing a Mg—Zn—Ca raw material and TiZr alloy;
- (b) induction melting a mixture of the Mg—Zn—Ca raw material and the TiZr alloy to form a melt;
- (c) cooling down the melt to form a Mg—Zn—Ca master alloy composite ingot;
- (d) remelting the Mg—Zn—Ca master alloy composite ingot;
- and
- (e) injecting the remelted Mg—Zn—Ca alloy composite melt into a mold to form a magnesium-based bulk metallic glass composite, wherein the magnesium-based bulk metallic glass composite is a single material including a Mg—Zn—Ca material and the TiZr alloy, and a particle size of the TiZr alloy is in a range from 25 μm to 45 μm.
