Abstract
The invention belongs to the technical field of surgical implants and relates to a preparation process of a titanium nitride-coated artificial joint. A titanium nitride coating formed on the surface of an artificial joint prosthesis has high biocompatibility and bioactivity and is capable of improving the hardness and wear resistance of the prosthesis. The titanium nitride coating on the surface of the artificial joint prosthesis is formed through a chemical reaction, is combined with substrate chemical bonds and is prevented from falling off, so that the long-term postoperative effect of the prosthesis is ensured; meanwhile, the artificial joint prosthesis is fixed biologically, so that the generation of bone cement fixing wear particles is avoided, the generating rate of aseptic loosening is lowered, and the service life of the artificial joint is prolonged.
Description
Technical field
The invention belongs to surgical implant technical field, relate to the preparation technology of the surfaces nitrided titanium coating of a kind of artificial joint.
Background technology
It is the first-selected Therapeutic Method of all kinds of ultimate joint diseases that prosthetic replacement is recognized.Yet along with prosthetic replacement's quantity constantly increases, the complication such as the prosthetic loosening being produced by this operation, sinking also increase, and have had a strong impact on clinical efficacy thereupon.
] titanium-based metal is because its density is little, intensity is high, proportion is close with body bone tissue and have the good advantages such as biocompatibility, is the main embedded material of current artificial joint prosthesis.But exist biological activity poor, can not induce bone growth; Anti-wear performance is poor, and the wear particle of generation easily brings out the aseptic loosening of prosthese; Can only rely on mechanical fixing and be combined with osseous tissue, cannot realize bone bonding with osseous tissue.
In prior art, mainly by HA coating, promote the osseous tissue prosthese of growing into, but have many problems: (1) coating degree of crystallinity is low,, in body fluid, easily to degrade, service life is short; (2) bond strength a little less than, after implanting, easily peels off; (3) expensive.Based on above reason, often cannot fundamentally realize biological activity and fix, the incidence rate that causes prosthetic loosening to sink is still very high, has had a strong impact on the service life of prosthese.
Glow ion nitriding, to utilize glow discharge principle, using metal works as negative electrode, put into the negative-pressure container being connected with containing nitrogen medium, nitrogen hydrogen atom after energising in medium is ionized, between anode and cathode, form ion plasma, under the effect of ion plasma highfield, the cation of nitrogen and hydrogen is to bombard to surface of the work at a high speed, the kinetic energy of ion changes heat energy into, and heated parts surface is to temperature required.Due to the bombardment of ion, surface of the work produces atom sputtering, thereby is purified, and due to absorption and diffusion, nitrogen infiltrates surface of the work then simultaneously.Compare with common gas nitriding, the feature of glow ion nitriding is: (1) nitriding cycle is short; (2) nitriding layer fragility is little; (3) can energy savings and the consumption of ammonia; (4) to not needing the part maskable of nitriding, realize selective nitriding; (5) ion bom bardment has purification surface action, can remove surface of the work passivating film; (6) alloying layer thickness is easy to control.
Titanium nitride coating is a kind of golden yellow thin film, have that hardness is large, corrosion resistance, with the advantage such as basal body binding force is strong, be industrial conventional abrasion-proof ceramic coat material.Research in recent years finds that titanium nitride coating has good histocompatibility, biological activity and anti-microbial property, has started application in oral cavity implanting tooth field, but up to the present, in artificial joint field, have not been reported.
Summary of the invention
The object of the invention is to for deficiency of the prior art, a kind of preparation technology who prepares titanium nitride coating on artificial joint surface is provided.
The technical solution adopted in the present invention is that the preparation technology of titanium nitride coating artificial joint, comprises the following steps.
Step 1, artificial joint prosthesis surface preparation.
Sanding and polishing is carried out on titanium-based metal artificial joint prosthesis surface, and ultrasonic waves for cleaning is processed.
Step 2, the preparation of the surfaces nitrided titanium coating of artificial joint prosthesis.
The good artificial joint prosthesis of sanding and polishing is placed on to glow ion nitrogen furnace negative electrode position, while being evacuated to 100Pa-200Pa after sealing, switch on power and start to beat arc, when voltage is increased to 400 ~ 800V, aura is lighted, and aura flash-point appears in prosthetic surface, passes into a small amount of ammonia, Control experiment temperature is 850-950 ℃, regulation voltage and electric current, make stove internal gas pressure be stabilized in about 300Pa to carry out nitriding, after reaction finishes, cool to room temperature with the furnace.
The advantage that the present invention has and beneficial effect.
Equipment required for the present invention and preparation technology are simple, with low cost, are easy to suitability for industrialized production; The titanium nitride coating of preparation, not only has good biocompatibility and biological activity, and has improved hardness and the anti-wear performance of prosthese.Because the surfaces nitrided titanium coating of artificial joint prosthesis forms by chemical reaction, with matrix chemical bonds, there is not the problem of surfaces nitrided titanium coating shedding, thereby the long-term postoperative of prosthese is guaranteed; Because artificial joint prosthesis adopts fix biology, avoid the fixedly generation of wear particle of bone cement simultaneously, reduced the incidence rate of aseptic loosening, extended the service life of artificial joint.
