beta SiC whiskers rau cov khoom siv dag zog

Daim ntawv thov ntawm silicon carbide whiskers beta SiCW silicon carbide whiskers:

Silicon carbide whiskers yog ib hom siv lead ua fiber ntau uas muaj qee qhov ntev-rau-inch piv, uas muaj qhov kub thiab txias ua haujlwm zoo thiab lub zog siab.Nws yog tsuas yog siv nyob rau hauv daim ntawv thov toughening qhov twg kub thiab siab zog daim ntaub ntawv yuav tsum tau.Xws li: aerospace cov ntaub ntawv, high-speed txiav cov cuab yeej.Tam sim no, nws muaj qhov ua tau zoo heev-tus nqi piv.Silicon carbide whiskers yog cubic whiskers, thiab pob zeb diamond yog ib daim ntawv siv lead ua.Lawv yog cov whiskers nrog lub siab tshaj plaws hardness, qhov loj tshaj plaws modulus, lub siab tshaj plaws tensile lub zog thiab lub siab tshaj plaws tshav kub kuj kub.Nws yog ob qho tib si α-hom thiab β-hom, uas β-hom kev ua tau zoo dua li α-hom thiab muaj zog dua (Mohs hardness ntawm 9.5 lossis ntau dua), zoo dua toughness thiab hluav taws xob conductivity, tiv thaiv hnav, kub tsis kam, tshwj xeeb tshaj yog av qeeg tiv thaiv Corrosion-resistant, hluav taws xob-resistant, tau siv rau aircraft, missile casings thiab cav, high-temperature turbine rotors, tshwj xeeb Cheebtsam.

Cia ntawm Beta Silicon Carbide Whisker:

silicon carbide whiskers yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw qhuav, txias, deb ntawm tshav ntuj ncaj qha.
