    Khoom cim npe

    Hlau Chrome Txhuas (FeCrAl) alloys yog cov khoom siv siab ua haujlwm feem ntau siv rau hauv cov ntawv thov nrog kev ua haujlwm siab tshaj plaws txog 1,400 ° C (2,550 ° F).

    Cov Ferritic alloys paub tias muaj peev xwm thauj khoom ntau dua, kev tiv thaiv siab dua thiab qis duaNickel Chrome(NiCr) lwm txoj hauv kev uas tuaj yeem txhais cov khoom siv tsawg dua hauv daim ntawv thov thiab qhov hnyav. Qhov siab tshaj plaws ua haujlwm kub kuj tuaj yeem ua rau lub neej ntev dua. Hlau Chrome Txhuas alloys tsim lub teeb grey Aluminium Oxide (Al2O3) ntawm qhov kub siab tshaj 1,000 ° C (1,832 ° F) uas ua rau muaj kev tiv thaiv corrosion ntxiv rau kev ua raws li hluav taws xob rwb thaiv tsev. Kev tsim oxide yog suav tias yog tus kheej-insulating thiab tiv thaiv luv luv Circuit Court nyob rau hauv cov kev tshwm sim ntawm hlau mus rau hlau sib cuag. Hlau Chrome Aluminium alloys muaj zog txhua yam muaj zog thaum piv rauNickel Chromecov ntaub ntawv nrog rau qis creep zog.
