Material has important market value.
Titanium alloy has good mechanical property and corrosion resistance, with skeleton similar density, is widely used in surgical device
Tool and body implant.But the wearability of titanium alloy is poor, coefficient of friction is higher, can be closed in use due to human body
Section activity causes serious abrasion, causes its service life too short, it is necessary to often change, influences therapeutic effect.In addition, its is wear-resistant
Damage performance deficiency also results in the loosening of implant, and chip caused by implant abrasion can also cause tissue reaction, trigger swelling and pain
Phenomena such as, more seriously, chip caused by abrasion can enter human body vitals by blood circulation, cause actual bodily harm,
Even threat to life.
The content of the invention
It is an object of the invention to provide a kind of medical titanium alloy and preparation method thereof, and it is wear-resisting to solve existing medical titanium alloy
The problem of performance deficiency, bioactivity difference.
The technical solution adopted in the present invention is a kind of medical titanium alloy and preparation method thereof, specifically according to following steps
Implement：
Zirconium 22%-25%, palladium 6%-9%, gallium：0.5%-1.5%, titanium are surplus, proportionally weigh raw material；
Melting：All raw materials are added into non-consumable heating in vacuum stove heat, are evacuated to vacuum as 3 × 10-3Pa-6×
10-3Pa, high-purity argon gas is filled with to 1.01 × 105Pa, is then smelted into alloy ingot at 1500 DEG C -1600 DEG C；
Casting：The ingot casting melted is subjected to remelting and ensures the uniformity of its composition, after melting between casting.
Heat treatment and cooling：The medical titanium alloy of casting is put into vacuum heat treatment furnace and is heat-treated, temperature
For 1000 DEG C -1200 DEG C, after being incubated 36-48 hours at such a temperature, furnace cooling.
The features of the present invention also resides in：
The titanium is 1 grade of titanium sponge；
The zirconium is pure zirconium；
The gallium is pure gallium.
The beneficial effects of the invention are as follows by improving the proportioning of zirconium and gallium in the feed, obtained titanium alloy is functional,
Casting surface is smooth, and alloy strength is high, and anti-wear performance is high, while avoids the addition of precious metal, cost-effective.After casting
Heat treatment and cooling so that the medical titanium alloy has preferable bioactivity, can melt well with people's body phase, reduce it is medical
Injury of the titanium alloy implant to human body.
