3. Cov yam ntxwv ntawm porous titanium phaj
Cov porous titanium phaj ua los ntawm titanium hlau hmoov muaj qhov zoo tshaj plaws corrosion kuj ntawm titanium, tuaj yeem tiv thaiv kev yaig ntawm ntau cov ntsiab lus ntawm nitric acid thiab feem ntau cov kua qaub-piv cov ntsiab lus, thiab tsis muaj tshuaj lom, muaj qhov kub thiab txias tsis kam, siab zog, thiab siab porosity, Nws muaj qhov zoo ntawm cov cua tsis sib xws thiab yooj yim tu.
Porous titanium ntawv muaj cov qauv sib xws, siab porosity, thiab zoo compressive zog. Nws yog feem ntau siv hauv qab 300 degree. Nrog zoo corrosion kuj thiab biocompatibility, nws yog dav siv nyob rau hauv hydrogen ntau lawm los ntawm lub zog tshiab, hydrogen roj cell electrode phaj, kev tiv thaiv ib puag ncig, hydrogen-oxygen ventilator, zaub mov purifier, nplua tshuaj kev lag luam, tshuaj kho mob, thiab lwm yam industries, precision pom, roj. Kev faib tawm, kev kho decarbonization, thiab kev cog qoob loo lom neeg.
4. Dab tsi yog daim ntawv thov ntawmporous titanium daim hlau?
Kev kho ozone ntawm cov dej haus thiab cov dej khib nyiab hauv kev lag luam yog cov cuab yeej tsim kho sai hauv tsev thiab txawv teb chaws hauv xyoo tas los no. Txoj kev no yog: ozone yog sib npaug rau hauv cov dej phwj tuaj los ntawm lub phaj ntxeem tau, thiab cov tshuaj lom neeg tshwm sim nrog cov dej phwj tuaj, thiaj li ua tiav lub hom phiaj ntawm kev tua kab mob, decolorization, thiab purification.
Yog li ntawd, lub phaj ntxeem tau yuav tsum tau tiv thaiv corrosion ntawm cov dej phwj tuaj thiab ozone thiab muaj cov porosity siab thiab cov pa roj, tusyees faib pore txoj kab uas hla, thiab qee lub zog. Yav dhau los, qee chav nyob hauv Suav teb uas siv cov txheej txheem ozone los kho cov dej phwj tuaj siv PVC perforated daim hlau, ceramic perforated daim hlau, iav perforated daim hlau, thiab lwm yam ntaub ntawv, tab sis lawv tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua vim tsis zoo corrosion kuj thiab tsis muaj zog. Porous titanium phaj daws qhov teeb meem loj no.
Tam sim no, porous titanium phaj tau siv los ua ozone diffusion phaj hauv kev kho dej phwj tuaj ntawm kev tsim thiab luam ntawv zaj duab xis, organic dye, roj refining, thiab tsev kho mob thiab foob pob ua ntxaij cav kuaj khiav. Hauv kev kho cov yeeb yaj kiab ua cov dej khib nyiab, lub neej kev pab cuam ntawm PVC perforated phaj tsuas yog 350 teev. Tom qab hloov nws nrog lub ntxeem tau titanium phaj, lub neej kev pabcuam tau nce mus rau 3 xyoos. Nyob rau hauv kev kho ozone ntawm refinery dej khib nyiab, PVC perforated phaj yog Ameslikas siv, tab sis ozone nqus tus nqi tsuas yog 65 feem pua, uas nkim ntau ozone thiab nce nqi ntawm kev kho dej khib nyiab. Tom qab siv lub phaj titanium ntxeem tau, tus nqi ozone nqus tau nce mus rau 85 feem pua, uas zoo heev rau kev kho mob.
5. Cov yam ntxwv thiab kev npaj ntawm cov khoom titanium ntxeem tau thiab titanium alloy cov ntaub ntawv
Porous titanium thiab titanium alloys ua ke cov khoom ntawm titanium alloys thiab cov ntaub ntawv ntxeem tau kom txo tau qhov hnyav ntawm cov khoom tsis muaj zog nws lub zog thaum tswj siab toughness thiab corrosion kuj. Yog li ntawd, ntxeem tau titanium thiab nws cov alloys muaj ib tug tseem ceeb daim ntawv thov nqi nyob rau hauv ib co tshwj xeeb teb, tshwj xeeb tshaj yog nyob rau hauv lub biomedical kev lag luam, vim porous titanium muaj ob qho tib si siab biocompatibility thiab zoo heev mechanical zog, yog li qhov zoo yog pom tseeb heev. Piv nrog rau tag nrho cov khoom titanium ntxeem tau, cov khoom siv titanium uas tsuas yog ntxeem tau ntawm qhov chaw muaj zog dua txhua yam thiab tuaj yeem tiv taus lub cev muaj zog ntau dua, yog li qhia txog kev nthuav dav hauv kev kho mob.
Cov ntaub ntawv ntxeem tau muaj cov qauv qhib uas tso cai rau cov pob txha tshiab thiab cov kua dej hauv lub cev, thiab Young's modulus ntawm cov ntaub ntawv ntxeem tau tuaj yeem hloov kho kom haum rau qhov porosity ntawm cov pob txha ntuj thiab txhim kho nws cov biomechanical compatibility. Porous titanium tau ntxim nyiam nyob rau hauv cov neeg kho mob vim nws zoo heev biocompatibility thiab zoo corrosion kuj. Porous titanium phaj muab ib qho kev xaiv tshiab rau kev kho mob thaum ntxov femoral taub hau necrosis, slows down txoj kev loj hlob ntawm tus kab mob thiab qeeb lub sij hawm ntawm kev sib koom tes hloov, thiab yog ib tug zoo txoj kev rau orthopedic kev kho mob ntawm ntxov femoral taub hau necrosis. Cov tshuaj niaj hnub ntseeg hais tias kev kho mob rau femoral taub hau necrosis yog kev phais. Cov kws tshaj lij hauv tsev thiab txawv teb chaws tawm tswv yim palliative phais rau cov necrosis ntxov, xws li core decompression, vascularized pob txha grafting, vascular implantation, thiab pob txha stenting. Late unavoidable dag pob qij txha hloov phais thiab lwm yam. Txawm li cas los xij, feem ntau, kev kho phais tsis raug lees txais los ntawm ntau tus neeg mob vim nws qhov mob hnyav, tus nqi siab, lub sijhawm rov qab los ntev, kev txwv dav, thiab tsis txaus siab rau lub sijhawm ntev. Yog li ntawd, siv txoj hauv kev zoo los tiv thaiv qhov tshwm sim thiab kev loj hlob ntawm femoral taub hau necrosis thiab txhawb kev tsim cov pob txha tshiab hauv thaj chaw necrotic tau dhau los ua qhov tseem ceeb ntawm cov kws kho mob orthopedic.
Tam sim no, txoj hauv kev los npaj cov ntaub ntawv titanium ntxeem tau yog raws li hauv qab no:
1. Hlau deposition txoj kev: Hlau deposition txoj kev mas muaj xws li lub tshuab nqus tsev evaporation method, electrodeposition method, plasma spraying, thiab reactive deposition method, cov uas feem ntau deposition txoj kev yog cov plasma spraying txoj kev. 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.
2. Cov txheej txheem ntawm lub xeev sintering: Txoj kev no feem ntau suav nrog cov txheej txheem hlau sintering, pore-forming tus neeg sawv cev ntxiv txoj kev, slurry foaming sintering method, template method, combustion synthesis method, thiab lwm yam.
ib. 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 tsim metallurgical bonds los ntawm high-temperature diffusion los npaj ntxeem tau 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.
b. Cov txheej txheem yog kom sib xyaw cov pore-forming tus neeg sawv cev thiab cov 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 los yog tom qab sintering kom tau ib tug ntxeem tau qauv. Cov txheej txheem muaj kev siv dav dav, txheej txheem kev npaj yooj yim, thiab cov pore faib tsis sib xws.
c. Txoj kev slurry foaming siv cov hmoov hlau ua raw khoom 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. Vim tias qhov kev txiav txim ntawm cov tshuaj ntxiv thiab tus neeg sawv cev foaming, cov pa roj pib nthuav dav, thiab tom qab sintering, Porous hlau tuaj yeem tau txais.
d. Cov txheej txheem template kuj tseem siv tau los npaj cov porous titanium. Feem ntau, daim txhuam cev yog siv los ua tus qauv, titanium slurry yog immersed nyob rau hauv lub template, thiab tom qab ziab, lub template raug tshem tawm los ntawm cua sov, thiab thaum kawg ntxeem tau titanium thiab nws alloy yog tau los ntawm high-temperature sintering.
3. Cov txheej txheem ua kua: Raws li qhov sib txawv ntawm cov cua sov, nws tuaj yeem muab faib ua cov kab hluav taws xob hluav taws xob cua sov txoj kev thiab laser engineering net txoj kev.
ib. Electron beam processing. Electron beam processing yog ib txoj kev ua haujlwm tshwj xeeb uas siv lub zog hluav taws xob uas tsim los thaum lub teeb hluav taws xob nrog lub zog muaj zog muaj zog cuam tshuam rau lub workpiece kom yaj thiab vaporize cov ntaub ntawv. Txoj kev no kuj yog ib txoj hauv kev siv hauv kev siv tshuab prototyping sai.
b. Laser engineering net shape method. Lub laser engineering net shaping txoj kev kuj yog ib hom kev siv tshuab prototyping sai. Lub tshuab no siv lub computer-aided tsim thiab ceev prototyping thev naus laus zis los hloov cov qauv khoom peb-dimensional rau hauv cov ntaub ntawv dav hlau thiab tom qab ntawd tsim cov CNC machining code, uas yog thaum kawg xa mus rau qhov chaw tswj thiab ua kom sov lub laser. Cov khoom siv molten yog txheej txheej los ntawm txheej los tsim cov khoom siv.
