Qhov sib txawv tseem ceeb ntawm nickel-based superalloys thiab cobalt-based superalloys nyob hauv lawv cov ntsiab lus matrix thiab cov yam ntxwv tseem ceeb ntawm kev ua haujlwm. cov
Nickel-based superalloys yog nyob ntawm nickel, thaum cobalt-based superalloys yog raws li cobalt. Nickel-based superalloys muaj lub zog kub kub zoo, oxidation tsis kam thiab corrosion kuj, thiab yog dav siv nyob rau hauv high-temperature Cheebtsam xws li aircraft xyaw thiab roj turbines.
Nyob rau hauv sib piv, cobalt-based superalloys muaj ntau dua thermal stability, oxidation kuj thiab kub corrosion kuj, yog li ntawd lawv ua tau zoo nyob rau hauv kub kub, siab siab thiab siab oxidation ib puag ncig. cov
Cov yam ntxwv ntawm npib tsib xee-raws li superalloys yog tias lawv ua raws li npib tsib xee, thiab txhuas, titanium thiab lwm yam khoom raug ntxiv los ua ib qho kev txhawb zog, uas muaj kev tiv thaiv oxidation zoo heev thiab kev nkag siab zoo.
Cov yam ntxwv ntawm cobalt-based superalloys yog tias lawv ua raws li cobalt, thiab cov kev daws teeb meem muaj zog yog ua los ntawm kev ntxiv chromium, tungsten, molybdenum thiab lwm yam, uas muaj ntau dua thermal stability, oxidation kuj thiab kub corrosion kuj. Hom alloy no tsuas yog siv nyob rau hauv aerospace, petrochemical thiab lwm yam kev lag luam, ntawm cov uas (GH3536) yog dav siv nyob rau hauv aerospace cav combustion chambers, afterburner thiab lwm yam khoom.
