Abstract
The present invention discloses an alloy, particularly a medical biologic titanium alloy for the dentistry, which is mainly used for clinical mouth rehabilitation, implantation, orthodontia, etc. The present invention is characterized in that the alloy is prepared from 5 wt% to 25 wt% of zirconium (Zr), 0.1 wt% to 0.2 wt% of palladium (Pd) and titanium (Ti) as the rest. The present invention has the following advantages that Zr and Pd which have complete compatibility with human bodies are adopted as alloy elements, so the alloy elements have favorable biocompatibility; the elastic modulus is low (from 80 to 90Gpa), which is lower than that of an Ti6Al4V alloy by 10% to 20%; because the alloy contains the active element Pd, the alloy has excellent corrosion resistance, and the corrosion rate is less than 0.0001 mm/a in normal saline solution; the present invention has good process compactibility, delta in the condition of heat treatment is from 18 to 25%, phi in the condition of heat treatment is from 45% to 55%, delta and phi are higher than those of the Ti6Al4V alloy by more than 50%, and the low hot-processing temperature is from 150 DEG C to 200 DEG C.
Description
Technical field
The present invention relates to a kind of alloy material, particularly a kind of tooth section biological medical titanium alloy is mainly used in clinical Oral Repair, plantation, just abnormal etc.
Technical background
Along with The development in society and economy, the raising of national life level and the aging of social population, market is obvious to the dental material demand growth impetus.Clinical investigation shows that titanium is just abnormal as tooth section, the demand of reparation, planting material is with 20～30% speed increment, becoming a class in the tooth section metallic substance has the novel material of development and application prospect most, but because titanium industry only has 50 years of development history, can be for the clinical tooth section that provides use the titanium alloy kind very little, what use at present mainly is commercial pure titanium and Ti6Al4V alloy.The intensity of pure titanium is still inadequate, and the Ti6Al4V alloy strength is higher, and has problems such as the toxicity of vanadium, processing performance is poor, biocompatibility is undesirable.Therefore research and develop biology, processing performance, the better tooth of comprehensive mechanical property section medical titanium alloy and become the target that countries in the world material supply section scholar chases.
Summary of the invention
The purpose of this invention is to provide a kind of good biocompatibility, corrosion resistance excellent, have the intensity of 600～900Mpa and have good comprehensive mechanical properties concurrently and the tooth section medical titanium alloy of technological forming performance, to overcome the deficiencies in the prior art, for a kind of dental material of the novel replacement is provided clinically.
Technical solution of the present invention is: a kind of tooth section medical titanium alloy, it is characterized in that it is made up of titanium (Ti), zirconium (Zr), palladium (Pd), the shared weight percent of each component is as follows: zirconium (Zr): (5～25) %, palladium (Pd): (0.1～0.2) %, titanium (Ti): surplus.
The shared weight percent of described each component can be: zirconium (Zr): (13～17) %, palladium (Pd): (0.14～0.16) %, titanium (Ti): surplus.
The present invention compared with prior art has following advantage:
1, complete compatible Zr, Pd of selection and human body has excellent biological compatibility as alloying element.
2, Young's modulus low (80～90Gpa), lower by 10～20% than Ti6Al4V.
3, owing to contain negative active component Pd, have excellent corrosion resistance nature, in normal saline solution, erosion rate is less than 0.0001mm/a.
4, better technological forming, the δ of as-heat-treated condition: 18～25%, : 45～55%, exceed more than 50% low 150～200 ℃ of hot processing temperature than Ti6Al4V alloy.
5, great variety of goods can be produced various metallurgic products such as plate, rod, silk, line, pipe, forging, foundry goods.
