Abstract
A process for decreasing the elastic modulus of Ti or Ti-alloy material by nano technique and increasing its biocompatibility includes such steps as loading the Ti or Ti-alloy material in a sealable metallic container, putting small steel pellets in it, fixing the container to a vibration generator, and high-speed vibrating to generate high-speed collision to obtain nanoparticles.
Description
Technical field
The present invention relates to the method for the reduction elasticity modulus of materials in material field, specifically is the method that a kind of nanometer reduces titanium and titanium alloy material Young's modulus.
Background technology
Titanium and titanium alloy have good biocompatibility, it is the main bio-medical metallic substance of a class, has widespread use at aspects such as orthopaedics, tooth sections, as a large amount of uses in the clinical artificial hip joint replacing is exactly the titanium alloy prosthese, but in uses such as hip replacement, find at present because the Young's modulus (about 110GPa) of titanium material is much higher than people's bone (about 30GPa), cause biomechanics not match thus, produce stress-shielding effect, this is the major cause that causes the hip replacement failure.Therefore, the Young's modulus of reduction titanium and titanium alloy material is one of important research content of bio-medical metallic substance.
Be the titanium material of development low elastic modulus, use the method for alloying usually.Mitsou Niinomi is being published in Metallurgical and Materials Transactions A, 33A, 2002:477-486. article " Recent Metallic Materials for Biomedical Applications " (" the up-to-date metallic substance of biomedical applications ", " metallurgical and material proceedings ", 33A, 2002:477-486.) in introduced by adding Nb, Ta, alloying elements such as Zr, Mo and reduced the method for titanium alloy elastic modulus and alloy designations thereof etc., these alloying elements make titanium alloy become beta structure, can reduce its Young's modulus.Alloying has improved the production cost of material, and can not be at pure titanium and the low Young's modulus of titanium alloy acquisition arbitrarily.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, provide a kind of nanometer to reduce the method for titanium and titanium alloy material Young's modulus, make it that common industrial titanium or titanium alloy material are carried out the nanometer processing, make the crystalline size in the titanium material be reduced to nanometer scale, thereby the titanium material of nanocrystal is because the atomic disorder at crystal boundary place is arranged and its Young's modulus of interatomic distance increase the reduction from common micron dimension.
The present invention is achieved by the following technical solutions, specific as follows: as pending titanium material to be fixed on to carry out high-speed shot blasting in the sealable metal vessel and handle, the small ball ball of in container, packing into, adopt a vibration machine that container is vibrated, drive the surface that the steel ball in the container clashes into titanium at high speed during the container high-speed motion, high-speed shot blasting is handled the crystal of titanium is broken up, and crystalline size is reduced to nanometer scale, and the titanium elasticity modulus of materials after nanometer is handled significantly reduces.
Pending titanium material is sheet material or bar, and container vacuumizes when avoiding handling the titanium material when handling oxidized, and vacuum tightness is greater than or equal to 10
-3Pa.
Steel ball ball size is 1-20mm, steel ball number 10-100.
The container vibrational frequency is 1-500Hz.Drive the surface that the steel ball in the container clashes into titanium at high speed during the container vibration, this high-speed shot blasting is handled and is made titanium generation severe plastic deformation from outward appearance to inner essence, distortion dislocation and distortion twin are bred in a large number in the crystal of titanium, and the crystal of titanium is broken up, and crystalline size reduces.
The time of shot peening has determined the size of nanocrystal, and the general treatment time is 10-200 minute.When shot peening behind certain hour, the crystalline size of titanium can be reduced to several to the hundreds of nanometers.The Young's modulus that nanometer is handled back titanium material significantly reduces.
The present invention is a kind of nano treatment technology that passes through, and makes the crystalline size in the titanium material be reduced to tens nanometer sizes from tens microns common sizes, and number of grain boundaries increases greatly in the titanium material of nanocrystal.Relevant physics formula:
E is the Young's modulus of material in the formula, and a is an interatomic distance, and k and m are constants.As seen, increase the Young's modulus that interatomic distance can reduce material.Therefore, the titanium material is by being reduced to crystalline size the nanometer size, can increase the number of grain boundaries in the material greatly, and crystal boundary place interatomic distance increases and atomic disorder is arranged the Young's modulus that can reduce material, therefore, the present invention is a kind of effective means by the Young's modulus that nanometer reduces the titanium material.
The present invention realizes reducing the Young's modulus of titanium material by nano processing technology, the Young's modulus that nanometer is handled back titanium material significantly reduces, when crystalline size is reduced to several nanometer, can reach the low elastic modulus of 40-50GPa, approach the Young's modulus of people's bone, thereby can significantly reduce stress-shielding effect, improve the biomechanical compatibility of titanium material, can effectively reduce the incidence of operative failures such as joint replacement etc.
