1. Dab tsi yog thawj cov ntawv thov ntawm Lork Nchuav Astm F90 \/ uns unsed R30605 forged co-w-ni alloy bar?
Teb:
Thawj daim ntawv thov ntawm Alloy bar yog nyob rau hauv kev kho mob kev lag luam, tshwj xeeb rau orthopedic kev cog lus. Nws yog ib feem siv los tsim cov khoom siv xws li hip thiab pob hauv paus uas xav tau biocompatibility, thiab muaj zog, tshuab muaj zog, thiab kev tiv taus rau corrosion hauv tib neeg lub cev.
2. Vim li cas Haynes 25 (Co-Cr-w-ni alloy) haum rau orthopedic kev cog lus?
Teb:
Haynes 25 (co-f-w-ni alloy) yog cov khoom siv zoo rau orthopedic kev cog lus vim nws tau ua tiav zoo ntawm:
Biocompatibility:Lub Alloy tsis yog ntxias cov kev cai lij choj thaum sib tiv thaiv lub cev cov ntaub so ntswg, ua rau nws haum rau lub sijhawm ua haujlwm ntev.
Siab lub zog thiab durability:Lub alloy muaj cov tshuab ua siab tshaj plaws muaj zog thiab hnav tsis kam, uas yog qhov tseem ceeb rau kev cog lus raug tshem tawm thiab txav mus los tas li.
Corrosion Kuj:Nws cov khoom ua kom zoo tsis kam mus rau corrosion, tshwj xeeb hauv kev sib nrug ntawm roj ntsha, ua kom muaj kev sib tw ntawm kev cog hniav.
3. Dab tsi yog cov cuab yeej siv cov tshuab ntawm ASTM F90 \/ uns uns r30605 forged co-w-ni alloy bar?
Teb:
Cov khoom siv mechanical ntawm cov alloy feem ntau suav nrog:
High tensile lub zog(feem ntau tshaj 1000 MPa)
Kev qaug zog zoo heev zog, ua rau nws haum rau cov ntawv thov kev ntxhov siab hnyav
Siab tawv(nruab nrab ntawm 35-45 hrc) rau hnav tsis kam
Zoo creep Kuj, uas yog qhov tseem ceeb rau kev ua tau zoo ntev hauv tib neeg lub cev cov khoom no tuaj yeem tiv thaiv cov ntawv thov kom nruj thaum lub sijhawm tswj hwm nws lub sijhawm.
4. Dab tsi yog cov txiaj ntsig ntawm kev siv Haynes 25 (co-cr-w-ni alloy) hauv kev tiv thaiv kev kho mob tshaj lwm cov ntaub ntawv?
Teb:
Kev hnav siab tsis kam:Haynes 25 muab kev tiv thaiv zoo rau kev puas tsuaj thiab hnav, uas yog qhov tseem ceeb rau kev cog lus ntev, tshwj xeeb tshaj yog nyob rau hauv cov lus taw qhia zoo li lub ntsag lossis lub hauv caug.
Corrosion Kuj:Lub alloy muaj cov kev tshwj xeeb tsis kam rau cov kev cuam tshuam ntawm lub cev ntawm lub cev, kom pom kev cog hniav yuav tsis txwv lossis poob lawv lub zog dhau sijhawm.
Bio-sib xyaw:Cov khoom siv no tau tsim tshwj xeeb rau kev siv tshuaj kho mob, txo qhov kev pheej hmoo ntawm kev phiv zoo li o lossis cov lus teb tsis haum.
Txhim kho cov khoom siv neeg kho tshuab:Haynes 25 muaj lub siab modulus ntawm elasticity thiab lub zog zoo, uas yuav pab tswj hwm cov qauv txheej txheem ntawm kev cog lus txawm tias nyob hauv cov nra hnyav.
5. Haynes 25 (co-cr-w-ni alloy) feem ntau ua rau cov ntawv thov kev kho mob?
Teb:
Haynes 25 yog feem ntau ua tiav los ntawm cov hauv qab no:
Forging thiab Rolling:Cov ntaub ntawv tuaj yeem raug rau hauv cov pas nrig, tuav, lossis lwm cov duab los tsim qhov ntev uas xav tau rau kev cog hniav. Cov txheej txheem no txhim kho kom muaj lub zog alloy lub zog thiab txhim kho nws cov khoom siv neeg kho tshuab.
Machining:Tom qab forging, lub alloy yog precisely machined tau ua kom tau raws li cov khoom siv tshwj xeeb ntawm cov khoom siv orthopedic, kom pom tseeb tias cov khoom haum kom raug thiab ua raws li tau txais.
Kev Kho Cua Sov:Kev kho cua sov yuav ua haujlwm txhawm rau txhim kho cov khoom siv lub zog, tawv tawv, thiab qaug zog tsis kam. Cov txheej txheem no tseem tuaj yeem pab ua kom tiav cov qauv zoo nkauj thiab cov khoom sib dhos rau cov khoom siv cog.
Xov Deg Plaub:Txhawm rau txhim kho biocompatibility thiab txo cov kev hnav, cov alloy tej zaum yuav dhau deg cov txheej txheem zoo li polishing lossis txheej.
