zida za silicon carbide
Mankhwala mwatsatanetsatane
Kuchuluka kwake ndikokwera, pamwamba kumakhala kosalala. Kutentha kwakukulu komanso kukhathamira kwakukulu komanso kusintha kwamphamvu, osasintha. Kuthetsa kukana, kutentha kwabwino kwa matenthedwe, osati zovuta. Kukaniza bwino kwa makutidwe ndi okosijeni, komwe kumawotcha mumoto wamakina osakaniza ndi kuchepetsa mpweya. Kodi kusintha mlingo magwiritsidwe wa uvuni ndi mlingo mphamvu zopulumutsa.
Poyerekeza ndi recrystallized and nitride bonded sic, magwiridwe anthawi yayitali a s-sintered sic ndiabwino. Mphamvu zosinthira zomwe sintered sic imaposa kawiri kuposa zomwe zimayesedwanso komanso pafupifupi 50% kuposa ya nitride yolumikizidwa.

Chidziwitso: Makulidwe pakufuna kasitomala
Makhalidwe
• ndalama zabwino kwambiri.
• Kulemera kopepuka komanso kuthekera kwakukulu.
• Kukaniza kwabwino kwambiri kutentha.
• Kutentha kwakukulu
• High Young modulus
• Kuchulukana kozama kwa kutentha
• Kuuma kwakukulu kwambiri
• Mphamvu zazikulu
• Valani zosagwira
• Kukaniza bwino kwa okosijeni

Tili zaka zoposa 10 zokumana nazo, zida zapamwamba komanso gulu la akatswiri pamundawu. Ndi kutsogolera mphamvu zamagetsi, kasamalidwe kabwino ka ntchito ndi ntchito yabwino, timazindikiridwa ndi makasitomala pamakampani opanga mafuta, mafuta, magetsi, zitsulo, zomangira, malo owonera, makina ndi mafakitale ena.
