Puas yog cov khoom tsim tawm ntawm cov hlau tsis muaj zog feem ntau yog alloy?
High resistance hluav taws xob cua sov alloy kuj hlau yog ib qho ntawm peb lub tuam txhab cov khoom tseem ceeb, muab faib ua ob series: hlau chromium txhuas thiab npib tsib xee chromium (hlau). Cov hlau no tau siv dav hauv kev tsim cov khoom siv cua sov thiab cov khoom siv hluav taws xob hauv pej xeem.
Yog li, koj puas tau xav txog vim li cas cov hlau tiv thaiv feem ntau yog ua los ntawm cov ntaub ntawv alloy? Cia wb mus saib qhov kev tshuaj ntsuam ntawm Yinxin Precision Alloy:
1. Txawm hais tias txhuas muaj kev tiv thaiv ntau dua li tooj liab, nws tsis ntau dua;
2. Tus nqi ntawm kev siv aluminium yog qis dua li ntawm kev siv tooj liab;
3. Aluminium muaj qhov ntom ntom ntau dua li tooj liab, thiab qhov hnyav ntawm cov xaim txhuas siv los nqa cov hluav taws xob tib yam tsawg dua. Nws yog qhov yooj yim dua rau nruab cov kab hluav taws xob, thiab tus nqi ntawm cov kab hluav taws xob yog qis dua;
4. Tus nqi ntawm txhuas hlau yog qis dua li ntawm tooj liab.
Ua ntej, peb txhua tus hauv daim teb no paub tias cov hluav taws xob cua sov ua haujlwm los ntawm kev hloov hluav taws xob rau hauv thermal zog, thiab inevitably cia siab rau qee yam cuab yeej los hloov hluav taws xob rau hauv thermal zog. Hluav taws xob cua sov raj yog tsim los ntawm cov hlau raj, insulating magnesium oxide hmoov, thiab hluav taws xob cua sov xov hlau. Yog li, cov hluav taws xob cua sov hlau ua haujlwm li cas hauv lub tshuab hluav taws xob cua sov? Niaj hnub no, peb yuav qhia rau koj thiab sib piv qhov sib txawv ntawm ob feem ntau siv high-temperature hluav taws xob cua sov xov hlau nyob rau hauv zus tau tej cov cua sov raj: muaj ntau ntau hom hluav taws xob cua sov xov hlau, uas yuav muab faib ua ob hom raws li lawv. Lub hom phiaj tseem ceeb thiab ntau npaum li cas, uas yog cov feem ntau siv. Cov hom hluav taws xob cua sov xov hlau tau muab faib ua raws li cov ntsiab lus ntawm cov khoom siv hluav taws xob thiab cov txheej txheem ntawm cov hluav taws xob cua sov hlau: hom hluav taws xob cua sov xov hlau yog hlau chromium aluminium alloy hluav taws xob cua sov xov hlau thiab nickel chromium alloy hluav taws xob cua sov xov hlau. Txhua tus muaj nws tus yam ntxwv. Ob hom hluav taws xob cua sov xov hlau, raws li cov khoom cua sov, muaj cov yam ntxwv sib txawv. Yog li thaum xaiv, nws yog ib qho tseem ceeb kom paub qhov twg koj siv nws.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm high-temperature hluav taws xob cua sov xaim yog tias cov khoom siv hluav taws xob cua sov hlau yuav tsum muaj qhov ua haujlwm siab. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov hluav taws xob cua sov hlau yog tib yam li lwm cov hlau cua sov, uas yog qhov tshwm sim ntawm hluav taws xob cua sov tom qab cov hlau yog electrified. Hluav taws xob cua sov yog hais txog lub cim ntawm ib tug npaum li cas ntawm cov cua sov los ntawm lub tam sim no dhau los ntawm ib tug conductor, uas yog ces kis tawm los ntawm tus neeg xyuas pib. Lub tshuab hluav taws xob cua sov nws tus kheej yog cov khoom siv hlau, uas yuav tawm cov cua sov thiab muab lub zog thermal tom qab hluav taws xob.
Cov lus piav qhia saum toj no yog hais txog feem ntau thiab feem ntau siv cov hluav taws xob hluav taws xob kub kub, uas tau muab faib ua ob hom no. Qhov laj thawj tseem yog lub hom phiaj. Vim li cas nws tsuas yog muab faib ua ob pawg loj? Qhov laj thawj yuav tsum yog tias hauv kev sim thiab kev ua haujlwm zoo tib yam, ob cov ntaub ntawv no yuav tsum ua kom ruaj khov thiab siv tau zoo.
