Cr3C2-NiCr ya anti-oxidation yapamwamba kwambiri komanso kukana kuvala
Kufotokozera
Cr3C2-NiCr ndi zinthu zophatikizika kwambiri zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale omwe amafunikira kutentha kwambiri komanso kukana kuvala.Zomwe zimapangidwa ndi chromium carbide (Cr3C2) ndi nickel-chromium (NiCr) alloy, zomwe zimapangitsa kuti zikhale njira yabwino yothetsera ntchito zomwe zimafunika kuti makutidwe ndi okosijeni azitentha kwambiri komanso kukana kuvala.
Makalasi a KF-70, KF-69, ndi KF-71 a Cr3C2-NiCr amadziwika chifukwa chakuchita bwino komanso kulimba kwawo pakutentha kwambiri.Kukula kwa tinthu kalasi iliyonse kumayambira 15-45 μm ndi 20-53 μm, ndipo iwo ali agglomerated ndi sintered kuonetsetsa mphamvu pazipita.
KF-70 Cr3C2-25NiCr imapereka kukana kwambiri kwa okosijeni ndi kuvala pa 815 ℃.Zimalimbikitsidwa kuti zigwiritsidwe ntchito m'malo otentha kwambiri omwe amafunikira kugwira ntchito kwanthawi yayitali, monga ma turbine blades ndi ma injini a gasi.
KF-69 Cr3C2-20NiCr ndi kalasi ina yabwino kwambiri yomwe imapereka kukana kwabwino kwa okosijeni ndi kuvala pa 815 ℃.Ndibwino kuti mugwiritse ntchito pamitundu yambiri yotentha kwambiri, kuphatikizapo kukonza mankhwala ndi kutentha kwa kutentha.
KF-71 Cr3C2-30NiCr ndi giredi yochita bwino kwambiri yomwe imapereka kulimba kwabwinoko kuposa magiredi ena abanja la Cr3C2-NiCr.Ndikofunikira kwambiri pakugwiritsa ntchito komwe kulimba ndi kulimba ndikofunikira, monga zida zobowola mafuta ndi gasi, nkhungu zotentha kwambiri, ndi zida zoponya.
Mwachidule, gulu la Cr3C2-NiCr lazinthu, kuphatikiza KF-70, KF-69, ndi KF-71, ndi yankho labwino kwambiri pamapulogalamu omwe amafunikira ma oxidation apamwamba kwambiri komanso kukana kuvala.Zogulitsazi zimapereka kulimba komanso kulimba kwapamwamba kwambiri pakatentha kwambiri, zomwe zimawapangitsa kukhala abwino kugwiritsidwa ntchito m'mafakitale monga zamlengalenga, zamagalimoto, ndi mphamvu.Ndi machitidwe awo abwino kwambiri komanso odalirika, zinthu za Cr3C2-NiCr ndi chisankho chabwino kwambiri kwa aliyense amene akufunafuna yankho lapamwamba, lokhalitsa kwa ntchito zotentha kwambiri.
