Hlau Chrome Txhuas Kev Tiv Thaiv Ntau Alloys
Hlau Chrome Aluminium (Fecral) alloys muaj cov ntaub ntawv siab tshaj plaws feem ntau siv nyob rau hauv cov ntawv thov kub txog 1,400 ° C (2,550 ° F).
Cov ferritic alloys tau paub kom muaj ntau dua qhov chaw thauj khoom, nce ntom ntom ntom nti (NICR) cov kev xaiv uas tuaj yeem txhais rau cov khoom siv thiab cov khoom siv hnyav. Qhov siab tshaj plaws ua haujlwm kub kuj tseem tuaj yeem ua rau lub neej ntev dua. Hlau Chrome Txhuas Alloys Form Ib lub teeb ci grey oxide (al2o3) ntawm qhov kub tshaj tawm nrog rau kev ua raws li insulator insulator. Cov Oxide tsim yog suav tias yog kev ua tus kheej thiab tiv thaiv kev tiv thaiv luv luv ntawm cov khoom siv luv luv ntawm cov hlau sib tiv thaiv. Hlau Chrome Txhuas Alloys muaj qis dua lub zog thaum piv rau Nickel Chrome cov ntaub ntawv nrog rau qis dua lub zog.
