Thoob plaws tib neeg cov keeb kwm, cov hlau uas muaj nqis muaj ib txwm nyob ntawm txoj haujlwm tshwj xeeb. Kub, nyiaj, platinum, etc., nrog lawv lub ntsej muag ci ntsa iab, muaj cov tshuaj me me, tau ua cov cim ntawm kev muaj nyiaj thiab muaj nuj nqis. Txawm li cas los xij, nrog kev txhim kho sai ntawm cov kev tshawb fawb thiab niaj hnub no, qhov tseem ceeb ntawm cov hlau uas muaj txiaj ntsig tau ntev ntev hauv cov thev naus laus zis.
Qhov kev ntxim nyiam tshwj xeeb thiab tso cai ib txwm muaj ntawm cov khoom siv hlau
Tej yam muaj txiaj ntsig feem ntau yog hais txog yim hlau cov ntsiab lus: KUB (AV), Rho tawm (Rhodium (OSMium (OS), thiab ruthenium (ru). Lawv muaj tsawg kawg nkaus hauv lub ntiaj teb kev ua kaub puab thiab muaj cov yam ntxwv ntawm qhov siab, siab yaj yaj, thiab cov tshuaj ruaj khov. Cov yam ntxwv no ua rau muaj cov nqi hlau nrov nrov nyob rau thaum ntxov ntawm tib neeg kev vam meej thiab tau siv dav hauv kev ua txiaj, cov hniav nyiaj hniav kub, thiab kev dai kom zoo.
Lub luag haujlwm tseem ceeb ntawm cov khoom muaj hlau hauv cov kev tshawb fawb thiab niaj hnub no
Niaj hnub no lub hnub nyoog niaj hnub no, cov ntaub ntawv hluav taws xob kev lag luam yog tawg, thiab cov hom me me ua si ib qho tseem ceeb txhawb txoj haujlwm hauv nws. Kub yog ib cov khoom siv tsis tau hauv cov khoom siv hluav taws xob. Nws cov kev ua tau zoo thiab corrosion tiv taus ua rau nws xaiv qhov zoo tshaj plaws rau kev txuas cov hluav taws xob sib txuas. Hauv qhov tseem ceeb xws li khoos phis tawj, txawb xov tooj ntawm cov xov hlau, thiab lwm yam kom ntseeg tau tias cov paib hluav taws xob tuaj yeem kis tau tias tau txais kev sib kis tau sai thiab ruaj khov. Peb lub tuam txhab feem ntau muab cov neeg siv khoom nrogKub-coated Tungsten cov xov hlaulossisKub Sputter Cov Hom Phiaj, uas tuaj yeem ua kom tiav qhov kev coj ua thaum txo tus nqi.
Hauv kev tiv thaiv ib puag ncig, platinum thiab palladium yog qhov tseem ceeb ntawm kev tso pa tawm ntau dua 90% ntawm cov pa roj teeb rau hauv cov khoom siv tsis zoo; Rhodium tseem ceeb txhim kho cov catalyst txoj kev ua kom huv rau cov nitrogen oxides. Peb tuaj yeem muab cov neeg siv khoom nrog cov khoom zoo99.95% Platinum Pt xaim, Palladium Ntawv Nyiaj, Platinum electrode pas nrig, thiab lwm yam khoom siv hlau muaj nqis.
Nyob rau hauv daim teb ntawm high-utidium muaj qhov melting point txog 2443 degree, uas yog qhov kev xaiv rau foob pob hluav taws. Nws tuaj yeem tiv taus cov roj teeb roj 3000 degree; Platinum-Rhodium alloy thermoco thermorot tuaj yeem ntsuas qhov kub ntawm 1800 degree, tiv thaiv cov ntsuas kub ntawm cov dav hlau tshuab tshuab. Peb liIridium ir hlauthiabPT IR xov hlauYog nrov heev nrog cov neeg siv khoom txawv teb chaws, thiab txawm tias ob peb lub tuam txhab tseem rov ua lawv cov. Yog tias koj txaus siab, koj tuaj yeem tiv tauj peb txhua lub sijhawm.
Hauv thaj teb ntawm Chip tsim, tswj hwm qhov tseeb ntawm nyias zaj duab xis nyob hauv cov phiaj xwm kev sib tw ua kom ntseeg tau tias qhov hluav taws xob ruaj khov ntawm cov chips hauv qab 7 nanometers; Rhodium plating yog siv rau nti txhuas thav ntawv txhim kho cov corrosion tsis kam ntawm cov cim ntsuas kev sib kis.

Cov nqi ntawm cov hlau ua si ib qho kev ua haujlwm irreplacesle hauv kev txhawb txuj ci tshiab thiab kev nce qib kev nce qib thiab kev txhim kho. Txawm hais tias muaj cov kev sib tw ntawm cov peev txheej tsis txaus ntseeg thiab cov hlau sib tw yuav ua kom muaj cov kev tswj hwm tshiab thiab tsim nyog muaj lub neej zoo rau noob neej. Raws li tus xa khoom ntawm cov khoom uas tsis yog-ferrous hlau nrog ntau dua 20 xyoo ntawm nws cov lus teb, cov lus teb zoo, kev ua haujlwm zoo tom qab muag khoom. Yog tias koj muaj lus nug txog cov khoom lag luam no cov ntsiab lus lossis lub sijhawm xa khoom, tsis txhob yig tau mus ntsib nrog peb ntawm {5}}. Peb tos ntsoov rau koj cov lus.
