Zirconium Alloys rau Orthopedic thiab Kho Hniav
Zirconium alloys rau kev siv biomedical tau txais kev saib xyuas ntxiv vim muaj ob lub zog tshwj xeeb: 1) tsim cov pob txha zoo li apatite txheej ntawm lawv qhov chaw hauv lub cev ib puag ncig, thiab 2) vim lawv zoo sib xws nrog kev sib nqus resonance imaging (MRI) diagnostics lawv tsawg magnetizability.
Hauj lwm lawm
Zirconium yog non-toxic, biocompatible hlau. Ntxiv nrog rau cov khoom siv zoo thiab zoo corrosion kuj, zirconium-raws li cov ntaub ntawv muaj ob lub zog tshwj xeeb rau orthopedic thiab kho hniav daim ntawv thov piv rau lwm cov khoom siv hlau biocompatible niaj hnub no. Ib qho yog qhov tsim ntawm cov pob txha zoo li cov txheej txheem nruab nrab ntawm lub cev, thiab lwm qhov yog lawv cov hlau nplaum tsawg. Cov cuab yeej thib ob yog qhov tseem ceeb tshwj xeeb rau kev sib nqus resonance imaging (MRI).
Khoom Description
Txij li ob qho tib si qhov zoo thiab qhov ceev ntawm MRI nyob ntawm qhov sib nqus lub zog, nws xav tau kom cov hlau nplaum muaj zog los ntawm tam sim no 1.0-1.5 T mus rau 3.0-7.{{5 }} T ntau. Txawm li cas los xij, tam sim no cov ntaub ntawv cog lus hlau xws li stainless hlau, cobalt-chromium alloys (hloov magnetizable) thiab titanium alloys ua magnetized nyob rau hauv 3.0-7.0 T magnetic teb tej yam kev mob. Cov txiaj ntsig muaj xws li cua sov ntawm qhov cog, loosening thiab dislocation ntawm qhov cog, thiab cov khoom siv tsis pom hauv MRI cov duab.
Lub magnetization ntawm tib neeg cortical pob txha yog kwv yees li -8.9 x 10 -6. Feem ntau, MRI-tshaj magnetization ntawm implanted cov ntaub ntawv yuav tsum tsawg tshaj li 10 x 10 -6. Ntawm cov khoom siv biocompatible thiab ductile hlau, zirconium muaj cov hlau nplaum tsawg heev, tab sis tseem zoo tshaj qhov sib xws. Cov kev tshawb fawb ua ntej tau pom tias los ntawm kev qhia ua tib zoo xaiv cov ntsiab lus rau hauv zirconium (lub npe hu ua "alloying"), nws muaj peev xwm txo tau cov hlau nplaum ntawm zirconium rau hauv MRI-tshaj ntau yam thaum ua rau cov zirconium alloys uas ua rau ntau yam tsim nyog rau kev cog qoob loo.

txog peb
Tau ntau xyoo, peb tau cog lus los tsim thiab muab cov hlau zoo thiab niaj hnub siv zog los txhim kho peb cov txheej txheem tsim khoom thiab cov khoom zoo. Peb lub hom phiaj yog los ua lub ntiaj teb ua lag luam cov khoom siv hlau thiab peb yuav txuas ntxiv mus nqis peev hauv cov cuab yeej tsim khoom thiab thev naus laus zis, txhim kho cov kev pabcuam zoo thiab kev daws teeb meem kev thauj mus los, thiab ua ntej cov neeg siv khoom txaus siab.
