Cov Cim Npe Khoom

Cov hlau Nickel Chrome (NiCr) yog cov khoom siv tiv taus siab uas feem ntau siv rau hauv cov ntawv thov nrog qhov kub siab tshaj plaws txog li 1,250 ° C (2,280 ° F).

Cov Austenitic alloys no paub txog lawv lub zog siab dua ntawm qhov kub thiab txias piv rau FeCrAl alloys nrog rau lawv lub zog nkag siab dua. Nickel Chrome alloys kuj tseem nyob ntau dua thaum piv rau FeCrAl alloys tom qab lub sijhawm ntev ntawm qhov kub thiab txias. Ib qho tsaus Chromium Oxide (Cr2O3) yog tsim ntawm qhov kub siab uas yooj yim rau spalling, lossis flaking, ua rau muaj kev ua qias tuaj yeem nyob ntawm daim ntawv thov. Cov oxide no tsis muaj cov khoom rwb thaiv tsev hluav taws xob zoo li Aluminium Oxide (Al2O3) ntawm FeCrAl alloys. Nickel Chrome alloys qhia txog kev tiv thaiv corrosion zoo tshwj tsis yog rau ib puag ncig uas muaj sulfur.
