Cov khoom siv hluav taws xob cua sov cov qauv kev ua tau zoo siv cov lus piav qhia (cov khoom siv taw qhia):
Cua sov hlau raws li nws cov ntsiab lus tshuaj lom neeg thiab microstructure ntawm qhov sib txawv, tuaj yeem muab faib ua ob pawg: ib qho yog hlau-chromium-aluminium alloy series, lwm qhov yog npib tsib xee-chromium alloy series, lawv yog cov khoom siv hluav taws xob cua sov muaj lawv tus kheej zoo, yog li nyob rau hauv domestic ntau lawm thiab dav siv.
Ua ntej, hlau-chromium-aluminium hluav taws xob cua sov alloy
1. Kub kub hauv qhov chaw
Kev siv kub ntawm hlau-chromium aluminium cua sov hlau tuaj yeem ncav cuag 1400 degree, thaum siv kub ntawm nickel-chromium hlau yog 1200 degree.
2. Lub neej ua haujlwm ntev
Raws li kev siv tib yam ntawm qhov kub thiab txias hauv huab cua, lub neej ntawm hlau-chromium aluminium tuaj yeem yog 2-4 npaug ntawm nickel-chromium.
3. High deg load
Txij li thaum cov hlau-chromium-aluminium alloy tso cai rau qhov kub thiab txias thiab lub neej ntev, qhov hnyav ntawm cov khoom siv kuj tuaj yeem siab dua, uas tsis tsuas yog ua rau cov cua kub ceev tab sis kuj txuag cov khoom siv alloy.
4. Zoo oxidation tsis kam
Lub al2o3 oxide zaj duab xis tsim nyob rau saum npoo ntawm cov hlau-chromium-txhuas alloy muaj cov paj ntom nti, thiab tsis yooj yim rau scatter paj thiab ntws thiab ua rau muaj kuab paug. Tsis tas li ntawd, Al2O3 muaj qhov siab tiv taus thiab siab melting point, uas txiav txim siab Al2O3 oxide zaj duab xis
Nws muaj oxidation zoo heev. Lub carburizing kuj tseem zoo dua li ntawm Cr2O3 tsim nyob rau saum npoo ntawm nickel-chromium alloys.
5. Me me lub ntiajteb txawj nqus
Qhov tshwj xeeb lub ntiajteb txawj nqus ntawm hlau-chromium-aluminium alloys yog me dua li cov nickel-chromium alloys, uas txhais tau hais tias kev siv hlau-chromium txhuas rau kev tsim cov khoom sib npaug yog ntau cov khoom-txuag tshaj nickel-chromium.
6. Siab resistivity
Lub resistivity ntawm hlau-chromium-aluminium alloys yog siab dua li ntawm cov nickel-chromium alloys, thiab cov ntaub ntawv alloy nrog cov kab uas loj dua tuaj yeem xaiv tau thaum tsim cov khoom, uas yog qhov tsim nyog rau kev ua haujlwm ntev ntawm cov khoom siv, uas yog qhov tseem ceeb tshwj xeeb rau cov hlau zoo. cov xov hlau.
7. Kev ua haujlwm zoo los tiv thaiv sulfur
Nws muaj kev tiv thaiv corrosion zoo rau cov huab cua uas muaj leej faj thiab ntog los ntawm cov tshuaj sulfur-muaj, thaum siv cov nickel-chromium yuav raug corroded hnyav heev.
8. Tus nqi pheej yig
Hlau-chromium txhuas yog pheej yig dua nyob rau hauv tus nqi txheeb ze tshaj nickel-chromium vim nws tsis muaj tsawg nickel.
9. Qhov tsis zoo ntawm cov hlau-chromium-aluminium alloy Tsis tshua muaj siab kub lub zog, thiab nws cov plasticity yuav loj dua li qhov kub thiab txias, uas yooj yim ua rau cov khoom siv deformation.
Qhov tsis zoo ntawm cov hlau-chromium-aluminium hluav taws xob cua sov alloy: feem ntau tsis tshua muaj siab kub lub zog, nrog rau kev siv qhov kub thiab txias, nws cov yas yuav loj dua, cov khoom siv tau yooj yim deform, tsis yooj yim rau khoov thiab kho.
