Titanium thiab stainless hlau yog ob qho tib si dav siv hauv engineering thiab cov khoom siv niaj hnub, tab sis "kev noj qab haus huv" nyob ntawmkoj siv nws rau dab tsi(cov khoom cog / kho mob, cookware, fwj dej, hniav nyiaj hniav kub / daim tawv nqaij, thiab lwm yam) thiab tseem nyob rauqib, nto tiav, thiab ib puag ncigcorrosive kua, qaub ncaug, hws, ntsev, cua sov).
Kev sib piv dav dav (kev noj qab haus huv- tsom)
1) Corrosion kuj / hlau tso tawm
TitaniumNws tiv taus corrosion heev vim nws tsim ib qho ruaj khov, tiv thaiv oxide txheej yuav luag tam sim. Hauv ntau lub cev- lossis ya raws- qhov chaw raug, titanium nyiam tso cov hlau ions tsawg heev.
Stainless hlaukuj tiv taus corrosion zoo, tshwj xeeb tshaj yog cov qib kev kho mob / zaub mov zoo li316L (thiab qee qhov lwm yam xws li 304/316 nyob ntawm daim ntawv thov). Txawm li cas los xij, stainless hlau tuaj yeem ua rau muaj qhov degradation ntau dua (piv txwv li, pitting, crevice corrosion, los yog hnav) nyob rau hauv qee yam mob hnyav, uas yuav ua rau me ntsis nce ion tso tawm.
Kev lag luam nqa tawm:Rau ib puag ncig uas nquag tawm tsam corrosion (kub / hws tej yam kev mob, ntev -lub sij hawm ntub dej, aggressive tu),titanium feem ntau suav hais tias yog qhov kev xaiv ntau "biocompatible".nyob rau hauv lub siab ntawm minimizing hlau ion raug.
2) Biocompatibility (kev kho mob cog)
Kev kho mob- qib titanium (piv txwv li, Ti-6Al-4V lossis kev lag luam ntshiab titanium)Nws yog feem ntau tshwm sim hauv orthopedic thiab kho hniav implants. Nws qhov chaw feem ntau yog qhov zoo rau kev sib cuag nrog cov ntaub so ntswg ntev.
Stainless hlau kuj tseem siv taunyob rau hauv tej yam khoom siv kho mob (thiab keeb kwm nyob rau hauv implants), thiab nws yuav ua tau biocompatible -tshwj xeeb tshaj yog hom alloy thiab tswj tej yam kev mob. Txawm li cas los xij, titanium tus cwj pwm corrosion feem ntau yog suav tias yog kev kwv yees ntau dua rau kev cog qoob loo ntev -.
3) Cov tawv nqaij tiv thaiv kev nplij siab (jewelry / watches / dermal raug)
Ob qho khoom siv feem ntau muaj kev nyab xeeb thaum sivsiab - qib zoothiabtiav tiav.
Cov neeg nrognickel rhiab heevyuav tsum tau them sai sai: ntau cov hlau tsis muaj hlau yuav muaj cov npib tsib xee, uas tuaj yeem ua rau muaj kev tsis haum tshuaj nyob rau hauv ib pawg ntawm cov tib neeg.
Titanium (tshwj xeeb yog cov ntshiab titanium lossis titanium alloys) feem ntau yogtsis yog npib tsib xee- muaj cov khoom, yog li nws feem ntau ua tau zoo dua rau npib tsib xee - cov tawv nqaij rhiab heev -txawm yog cov hlau tuaj yeem ua rau khaus yog tias qhov chaw ntxhib los yog muaj kab mob.
Kev lag luam nqa tawm:Yog tias koj qhov kev txhawj xeeb yog "zoo rau kev sib cuag ntawm daim tawv nqaij,"titanium feem ntau muaj qhov zoo rau kev ua xua npib tsib xee- cov neeg nyiam, thaum stainless hlau zoo thiab muaj pes tsawg leeg tseem ceeb heev.
Thaum "stainless steel" tej zaum yuav zoo li noj qab haus huv
Rau ntau yam kev siv txhua hnub -zoo lichav ua noj cookware, fwj dej, ntim khoom noj-zoozaub mov-hu rau qib stainless hlau(feem ntau 304 lossis 316) suav tias yog kev nyab xeeb thiab siv dav. Yog tias:
nws yog tsim los rau zaub mov / dej sib cuag,
qhov saum npoo yog du,
nws tau siv raws li kev npaj (tsis muaj acids hnyav rau lub sijhawm ntev),
thiab nws tsis hnav / khawb qhov tseem ceeb,
ces stainless hlau tuaj yeem ua tau zoo rau kev siv niaj hnub.
Hauv qab kab
Rau ntev -lub cev tiv tauj / implants / minimizing corrosion- hais txog hlau ion tso tawm: Titanium feem ntau yog qhov kev xaiv noj qab haus huv.
Rau cov khoom noj txhua hnub lossis dej sib cuag nrog cov qib kom raug thiab siv: Stainless hlau tuaj yeem muaj kev nyab xeeb sib npaug, thiab qhov sib txawv feem ntau me dua li cov neeg xav.
Rau cov neeg uas muaj nickel rhiab heev: titanium feem ntau yeejvim nws feem ntau zam cov nickel raug.
