Yuav ua li cas tuaj yeem smelting ua kom muaj kev coj dawb huv thiab kev ua tau zoo?

Titanium Nickel alloy tau dhau los ua cov khoom tseem ceeb thiab kev siv tshuaj kho mob xws li nws cov nyhuv cim, thiab biocompatibility. Nws qhov kev ua tau zoo yog nyob ntawm kev tswj hwm ntawm cov txheej txheem melting, thiab cov txheej txheem ntawm kev cais tawm lossis cov kab zauv uas tuaj yeem ua rau kev ua tau zoo sai li. Los ntawm cov kev pom ntawm tag nrho cov txheej txheem ua haujlwm, txheeb xyuas cov ntsiab lus tseem ceeb kom ntseeg tau tias muaj kev ua tau zoo ntawm cov alloys.

Cov khoom siv raw ua ntej melting yog thawj kab ntawm kev tiv thaiv rau kev paub tseeb. Daim txhuam cev titanium nrog lub purity ntawm ntau dua los yog sib npaug rau 99.8% yuav tsum tau xaiv los ntawm ntau dua lossis cov pa roj ntsha, nrog cov ntsiab lus ntawm cov roj ntsha uas tsawg dua lossis sib npaug rau 0.05%). Cov khoom siv ua ntej tau tsis quav ntsej tias: Titanium raw khoom siv ntawm ethydrous ib puag ncig thiab oxide cov yeeb yaj kiab, zam kev tsim cov oxide suav ua thaum lub sij hawm yaj. Nyob rau tib lub sijhawm, kev npaj ntawm cov electrodes constrodes yuav tsum siv cov tshuab hluav taws xob tau tswj hwm saum toj no 4.2g / cm los tiv thaiv cov roj tsis tiav vim yog siv hluav taws xob.

Smelting khoom thiab ib puag ncig tswj yog cov tseem ceeb txhawb. Lub Tshuab nqus tsev tau muaj ARC melting rhuab hluav taws xob feem ntau siv hauv kev lag luam. Ua ntej melting, lub rauv taws yuav tsum tau nqus thiab muaj kev sib luag ntawm 1 × 10 ⁻ 10 × 10 ⁻ 10 itrogen oxes xws li nitrogen oxes nyob rau hauv huab cua. Kev Purity High Argon nrog lub purity ntawm ntau dua los yog sib npaug ntawm cov pa roj teeb lub qhov cub, thiab nws yuav tsum tau mus sab hauv cov pa roj cua sov (de Thaum lub sijhawm siv hluav taws xob, nws yog ib qho tsim nyog yuav kom ntseeg tau tias kev sib txawv tsawg dua los yog sib npaug ntawm cov txheej txheem kev tawm tsam hauv cheeb tsam thaum lub sij hawm melting txheej txheem, ua rau tsis sib xws.

Cov ntsuas tswj cov txheej txheem smelting ncaj qha txiav txim siab qhov ua tau zoo. Thaum lub sij hawm arc pib theem, qhov qis}-}} {{{{12} {{{12} {{12} {{ Thaum lub sijhawm yaj yaj, nws yog ib qho tsim nyog los tswj qhov kub ntawm Molten Rauv ntsuas kom tsis txhob muaj qhov kub ntawm lub sijhawm 16668 degree) lossis theem pib ua haujlwm los ntawm qhov kub tsawg. Txhawm rau kom ua tiav cov kev sib xyaw ua ke, 3-4 lub ntsej muag ntawm melting yog xav tau, nrog lub sijhawm 10 feeb los ua kom muaj kev hloov pauv ntawm kev sib txawv

Ncej melting kho thiab kev tshuaj xyuas zoo yog cov tshev kawg. Alloy Ingots yuav tsum tau txias nyob rau hauv lub cub tawg kom qis dua 200℃ua ntej raug tshem tawm kom tsis txhob txias thiab tshwm sim ntawm martensitic hloov pauv brittleness. Sai li sai tau tom qab ua ci, kev kho qab saum npoo yog nqa tawm kom tshem tawm cov 1-} 2 hli tuab oxide txheej thiab titanium tsis muaj txheej. Tom qab ntawd, lub deg ntsiab lus impurity yog kuaj pom los ntawm x-tshav fluorescence spectroscopy kom ntseeg tau tias tsawg dua lossis sib npaug rau 0.005% yog tsawg dua lossis sib npaug nrog 0.005%. Cov kev sim sab hauv zoo siv kev sim ultrasonic (UT) thiab yuav tsum tau ua raws cov qauv hauv chav kawm, tsis muaj qhov hws nrog ntau dua lossis sib npaug nrog 0.5 hli.

Qhov melting ntawm titanium npib alloy yog qhov kev ua kom zoo nkauj ntawm "kev ntsuas rawing ntawm txhua kauj ruam", los ntawm raw kuaj ntawm txhua kauj ruam ", los ntawm raw kuaj ntawm kev soj ntsuam, txhua qhov txuas ncaj qha cuam tshuam nrog kev coj dawb huv thiab kev ua tau zoo. Tsuas yog los ntawm nruj me ntsis tom qab lub tshuab ua haujlwm ntawm lub tshuab nqus ib puag ncig tuaj yeem txhim khu kev qha ntawm alloys tau ua tiav hauv high-} daim teb kawg.
