"Peb tab tom siv Titanium - Tsis Yog Qhov Kho Mob Twb Tau -Pam lawm?"
"Peb xaiv titanium. Nws yog biocompatible, muaj zog, thiab dav siv hauv kev cog qoob loo. Yog li thaum nws luam tawm, peb zoo mus ... txoj cai?"
Tsis heev.
Yog tias koj tab tom ua haujlwm nrog Hlau 3D Printing, tshwj xeeb tshaj yog Titanium Alloy 3D Printing lossis nrhiav los ntawmTitanium 3D Printing Service, ntawm no yog qhov tseeb:
Kev kho mob -qib titanium qhov chaw tsis yog txhais los ntawm cov khoom ib leeg - lawv raug txhais los ntawm qhov lawv tau tshaj tawm - ua tiav, tswj, thiab siv tau.
Qhov tseeb, feem ntau ntawm "kev kho mob- qib" yuav tsum tshwm simtom qab luam ntawv, tsis yog thaum.
Cia peb taug kev los ntawm qhov ua rau titanium ncej- ua tiav hauv daim ntawv thov kev kho mob sib txawv - hauv txoj kev pom tseeb, siv tau.
Vim li cas Kev Kho Mob Titanium Post-Kev ua haujlwm yog qhov xav tau ntau dua li qhov koj xav tau
Titanium alloys (zoo li Ti-6Al-4V) tau dav siv vim:
biocompatibility zoo heev
corrosion kuj
siab zog-rau- hnyav piv
Tab sis ntawm no yog lub ntsiab lus tseem ceeb:
Raws li - cov khoom titanium luam tawm tsis tau npaj rau kev siv kho mob.
Lawv feem ntau muaj:
Qhov chaw ntxhib (Ra 5-15 μm)
kev ntxhov siab sab hauv
residual hmoov
microstructural inconsistencies
Yog vim li cas kev tshaj tawm -kev ua haujlwm tsis yog xaiv tau - nws yog qhov tseem ceeb.
Cov Ntsiab Cai Tshwj Xeeb rau Kev Kho Mob Titanium Post-Kev Ua Haujlwm
1. Kev Tiv Thaiv Kev Nyuaj Siab thiab Kev Tiv Thaiv Thaum Tshav Kub Kub
Vim li cas nws tseem ceeb:
ThaumHlau 3D Printing, laser tsim:
ceev cua sov thiab txias
internal residual stress
Yog tsis kho:
qhov chaw tuaj yeem deform
mechanical zog ua inconsistent
Kev kho mob xav tau:
tswj kev kho cua sov cycles
cov ntaub ntawv parameter
repeatability nyob rau hauv batch
Raws li cov ntaub ntawv kev lag luam:
Kev ntxhov siab thiab kev kho cua sov yog qhov yuav tsum tau ua kom ruaj khov microstructure thiab kev ua haujlwm
Hauv cov ntsiab lus yooj yim:
Tsis muaj kev kho cua sov tswj=tsis sib xws.
2. HIP (Kub Isostatic Pressing) rau cov khoom kho mob tseem ceeb
HIP yog dab tsi?
Kub kub + kev kub siab txheej txheem
tshem tawm cov porosity sab hauv
Vim li cas kev lag luam kho mob xav tau nws:
implants yuav tsum muaj nyob ze -zero internal defects
lub neej qaug zog yuav tsum tau kwv yees
Hom mob HIP:
900-950 degree
siab - ib puag ncig siab
Tshwj xeeb tshaj yog tseem ceeb rau:
load-cov kabmob implants
ntev - cov khoom siv kho mob
3. Kev ua tiav saum npoo tsis yog hais txog qhov tshwm sim xwb
Qhov no yog qhov uas ntau buyers underestimate qhov yuav tsum tau.
Raws li - luam tawm titanium nto:
semi-melted particles
ntxhib ntxhib ntxhib los mos
muaj peev xwm kis tau
Kev kho mob xav tau:
Qhov saum npoo yuav tsum yog:
huv si
tswj roughness
corrosion-resistant
Cov txheej txheem muaj xws li:
sandblasting
polishing
electropolishing (mus rau Ra 0.2-0.4 μm)
Vim li cas nws tseem ceeb:
Kev tshawb fawb qhia tias:
Kev hloov kho saum npoo ncaj qha txhim kho biocompatibility thiab kev sib xyaw ntawm pob txha
Qhov saum npoo yog qhov lub cev "pom" - tsis yog cov khoom hauv.
4. Advanced Cleaning thiab Contamination Control
Kev kho mob titanium qhov chaw yuav tsum yog:
dawb hmoov
tsis muaj roj
dawb ntawm chemical residues
Cov txheej txheem ntxuav muaj xws li:
ultrasonic tu
tshuaj ntxuav
internal channel flushing
Raws li ISO 10993:
Cov ntaub ntawv yuav tsum tsis txhob ua rau muaj tshuaj lom, inflammatory, lossis tiv thaiv kab mob
Qhov ntawd txhais tau tias txawm tias microscopic paug tuaj yeem ua rau tsis ua haujlwm.
5. Nto Chemistry thiab Oxide Txheej Tswj
Titanium ib txwm tsim cov txheej txheem oxide uas:
tiv thaiv corrosion
txhim kho biocompatibility
Tab sis kev tshaj tawm - ua tau:
txhim kho txheej txheej no
los yog ua puas rau nws
Kev kho mob xav tau:
tswj qhov chaw chemistry
ruaj khov oxide txheej
tsis muaj kev xav tsis zoo
Kev ua haujlwm tsis zoo=nce ion tso tawm txaus ntshai.
6. Kev soj ntsuam tag nrho thiab siv tau (tsis yog xaiv tau)
Cov khoom kho mob xav tau ntau dua li kev kuaj pom.
Yam validation muaj xws li:
CT scanning (kev puas tsuaj sab hauv)
kev kuaj tensile
metallographic tsom xam
qhov ntsuas qhov ntsuas
Raws li kev lag luam kev lag luam:
Kev tshuaj xyuas tag nrho ua kom muaj kev ntseeg tau ntawm cov khoom siv thiab cov qauv
Thiab txhua kauj ruam yuav tsum tau sau tseg.
7. Tag nrho Traceability thiab cov ntaub ntawv
Qhov no yog ib qho ntawm qhov sib txawv loj tshaj plaws thiab cov khoom lag luam.
Kev kho mob- qib yuav tsum muaj xws li:
hmoov batch traceability
cov ntaub ntawv txheej txheem
tus neeg tsav tsheb cav
kev tshuaj xyuas
Raws li txoj cai kev cia siab:
tag nrho cov saw hlau tsim khoom yuav tsum tau sau tseg rau kev pom zoo
Tsis muaj traceability=tsis muaj kev pom zoo.
