Vim tias cov khoom ntxeem tau muaj cov qauv qhib, uas tso cai rau kev loj hlob ntawm cov pob txha tshiab thiab cov kua dej hauv lub cev, thiab cov Young's modulus ntawm cov khoom ntxeem tau tuaj yeem ua tau.
kho kom haum cov porosity ntawm cov pob txha ntuj thiab txhim kho nws biomechanical compatibility. Porous titanium tau txais kev saib xyuas ntau hauv cov zej zog kho mob vim
nws zoo heev biocompatibility thiab zoo corrosion kuj. Tam sim no, nws txoj kev npaj muaj cov hauv qab no:
1. Lub xeev sintering txoj kev
Cov txheej txheem feem ntau muaj xws li hlau sintering txoj kev, pore-forming tus neeg sawv cev ntxiv txoj kev, slurry foaming sintering txoj kev, template txoj kev, combustion
txheej txheem synthesis, thiab lwm yam.
1) Cov hlau stacking sintering txoj kev yog ib txoj kev ntawm sintering lub stacked hollow spheres los yog hmoov nyob rau hauv high kub thiab ua metallurgical bonds los ntawm siab.
kub diffusion los npaj porous hlau. Tsis tas li ntawd, txoj kev xaim winding tuaj yeem siv los ua ib qho khoob thiab tom qab ntawd sinter los npaj cov khoom ntxeem tau.
2) Txoj kev no yog kom sib tov cov pore-forming tus neeg saib xyuas thiab titanium hmoov nyob rau hauv ib qho kev faib ua feem, thiab ces tshem tawm cov pore-forming tus neeg saib xyuas los ntawm cua sov los yog dissolving.
ua ntej lossis tom qab sintering kom tau txais cov qauv ntxeem tau. Cov txheej txheem muaj kev siv dav dav, txheej txheem kev npaj yooj yim thiab cov pore faib.
3) Txoj kev slurry foaming siv cov hmoov hlau ua cov khoom siv raw, thiab npaj rau hauv slurry los ntawm kev ntxiv cov foaming agent, thiab lwm yam, thiab tom qab ntawd ntxiv rau pwm rau cua sov.
Porous hlau tuaj yeem tau txais.
4) Cov qauv qauv kuj tseem siv tau los npaj cov porous titanium. Feem ntau, daim txhuam cev yog siv los ua qauv, titanium slurry yog immersed nyob rau hauv lub template, thiab tom qab ziab,
template raug tshem tawm los ntawm cua sov, thiab thaum kawg ntxeem tau titanium thiab nws alloy yog tau los ntawm kub sintering.
2. Txoj kev ua kua solidification
Raws li cov cua kub sib txawv, nws tuaj yeem muab faib ua electron beam heating forming method thiab laser engineering net forming method.
1) Electron beam processing
Electron beam processing yog ib txoj kev ua haujlwm tshwj xeeb uas siv lub zog hluav taws xob uas tsim los ntawm lub zog hluav taws xob siab ceev hluav taws xob los cuam tshuam cov khoom ua haujlwm kom yaj thiab
vaporize cov khoom. Txoj kev no kuj yog ib txoj hauv kev siv hauv kev siv tshuab prototyping sai.
2) Laser engineering net shaping txoj kev
Lub laser engineering net shaping txoj kev kuj yog ib hom kev siv tshuab prototyping sai. Cov tshuab no siv computer-aided tsim thiab sai prototyping technology rau
hloov cov qauv peb-dimensional khoom rau hauv dav hlau cov ntaub ntawv, thiab tom qab ntawd generates CNC machining code, uas yog thaum kawg kis mus rau lub chaw tswj thiab heats lub
laser. Cov khoom siv molten yog txheej txheej los ntawm txheej los tsim cov khoom siv.
3. Hlau deposition txoj kev
Cov txheej txheem hlau deposition feem ntau suav nrog lub tshuab nqus tsev evaporation, electrodeposition, plasma spraying thiab reactive deposition, ntawm cov uas feem ntau deposition txoj kev.
yog plasma txau. Feem ntau, plasma spraying muaj qhov tshwj xeeb zoo hauv kev npaj cov yeeb yaj kiab nyias lossis txheej txheej, thiab cov txheej txheem kuj tseem siv tau los ua cov hlau ntxeem tau.
