Description
Technical field
The present invention relates to a kind of preparation methods of porous Ti-5Ag alloy.
Background technique
Compared with traditional medical stainless steel and cobalt-base alloys, titanium and its alloy are due to its excellent mechanical property, biology
The advantages that compatibility and corrosion resistance, it is clinically widely used as orthopaedics and dental implant at present.However, although titanium and its
The elasticity modulus of alloy is lower than medical stainless steel and cobalt-base alloys, but still higher than bone tissue.The mismatch of this elasticity modulus
It can cause " stress shielding " effect, lead to the failure of osteoporosis and implant.Solve elasticity modulus mismatch method first is that
In titanium and its alloy introduce porous structure be prepared into porous metal material, thus reach be mitigated or eliminated stress shielding effect and
Extend the purpose of implant service life.In addition, POROUS TITANIUM and its unique porous structure of alloy enable bone tissue to grow into
Hole and body fluid transmit inside implant, can promote bone tissue regeneration and the combination improved between implant and bone tissue is strong
Degree.There are many methods of preparation POROUS TITANIUM for report at present, such as loose sintering method, Polymeric sponge method, solid-state foaming, slurry
Foaming, plasma spraying method, space occupy-place method, speed forming method etc., these methods respectively have advantage and disadvantage, wherein space occupy-place method
Have many advantages, such as hole shape, pore-size distribution and adjustable porosity.Urea and ammonium hydrogen carbonate (NH4HCO3) be exactly two of them have it is latent
The occupy-place agent of power, they are heated in a low temperature of 200 DEG C can resolve into gas exclusion, and will not react with titanium, therefore
Space occupy-place method is a kind of promising method for preparing porous titanium or titanium alloy.Although metal implant is in implantation using tight
The aseptic condition of lattice and it is postoperative use antibiotic, however material implantation after postoperative infection still cause more and more to pay close attention to.
Therefore, researcher attempts to develop, and there is the metal implant of antibiotic property to solve infection problems.Silver have strong sterilizing function and
Spectrum bactericidal effect.Therefore it regard silver as alloy element, is expected to develop antibacterial titanium alloy implant.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of porous Ti-5Ag alloy.
The present invention is realized by following technical solution:
A kind of preparation method of porous Ti-5Ag alloy includes the following steps: 30-40 parts of Ti powder and 5-15 parts of Ag powder ball is added
In grinding jar, abrading-ball is added by ratio of grinding media to material 10: 1,10-20 parts of dehydrated alcohols are added and carry out ball milling, with the revolving speed ball milling of 300r/min
2.5-3.5h；Ti-Ag powder is uniformly mixed with 20-30 parts of ammonium hydrogen carbonate, then by mixture under the pressure of 150-160MPa
Be pressed into 15mm × 25mm × 10mm cuboid sample, by the sample suppressed be put into vacuum sintering furnace under vacuum conditions into
Row sintering first removes ammonium hydrogen carbonate in 185-195 DEG C of heat preservation 2.5-3.5h, then in 870-890 DEG C of heat preservation 3-4h, cooling to obtain the final product；
Each raw material is parts by weight.
Preferably, in the preparation method, with the revolving speed ball milling 3h of 300r/min.
Preferably, in the preparation method, mixture is pressed under the pressure of 155MPa 15mm × 25mm ×
10mm cuboid sample.
Preferably, in the preparation method, ammonium hydrogen carbonate is removed in 190 DEG C of heat preservation 3h.
