Khoom cim npe

Nickel Chrome (NiCr) alloys yog cov khoom siv tiv thaiv siab feem ntau siv rau hauv cov ntawv thov nrog qhov kub siab tshaj plaws ua haujlwm txog 1,250 ° C (2,280 ° F).

Cov Austenitic alloys paub txog lawv lub zog siab dua ntawm qhov kub thiab txias piv rau FeCrAl alloys nrog rau lawv lub zog siab dua. Nickel Chrome alloys tseem nyob twj ywm ntau dua thaum piv rau FeCrAl alloys tom qab ncua sij hawm ntawm qhov kub thiab txias. Ib qho tsaus nti Chromium Oxide (Cr2O3) yog tsim nyob rau ntawm qhov kub thiab txias uas muaj kev cuam tshuam rau spalling, los yog flaking, ua rau muaj kev paug paug nyob ntawm daim ntawv thov. Cov oxide no tsis muaj hluav taws xob rwb thaiv tsev zoo li Aluminium Oxide (Al2O3) ntawm FeCrAl alloys. Nickel Chrome alloys pom zoo corrosion kuj tshwj tsis yog rau ib puag ncig uas muaj leej faj.
