| titleOfInvention | A kind of titanium alloy/calcium pyrophosphate surface layer Biocomposite material and preparation method thereof |
| abstract | The invention discloses a kind of titanium alloy/calcium pyrophosphate surface layer Biocomposite materials and preparation method thereof, belong to biomedical materials field.For skin layer composite material according to the present invention using titanium alloy as matrix, calcium pyrophosphate+zirconium is biological ceramic layer.Its processing step is：It will be dried after titanium, niobium, 6 ~ 8h of zirconium powder mechanical alloying, obtain titanium alloy mixed-powder；It is dried after calcium pyrophosphate is mixed 1 ~ 2h of powder with zirconium powder ball milling, obtains calcium pyrophosphate mixed-powder.Then titanium alloy mixed-powder and calcium pyrophosphate mixed-powder are respectively charged into the upper and lower layer of graphite jig by auxiliary device, sintering in discharge plasma sintering stove is placed in after compacting and obtains titanium alloy/calcium pyrophosphate surface layer Biocomposite material.Skin layer composite material interface cohesion prepared by the present invention is good, intensity is suitable, surface bioactive is excellent, composite bed thickness reaches as high as 10mm, it substitutes and repairs available for human body hard tissue, and preparation process is clean, simple for process, of low cost, it is easy to accomplish industrialized production. |
