Silicon carbide ceramics: Chimodzi mwazinthu zodziwika bwino za bulletproof ceramic

Silicon carbide covalent bond ndi yamphamvu kwambiri, imakhalabe ndi mphamvu zambiri zomangirira pa kutentha kwakukulu, mawonekedwe opangidwawo amapereka silicon carbide ceramics mphamvu zabwino kwambiri, kuuma kwakukulu, kukana kuvala, kukana dzimbiri, kutsekemera kwapamwamba kwambiri, kukana kutenthedwa kwa kutentha ndi zina; Panthawi imodzimodziyo, mtengo wa silicon carbide ceramics ndi wochepetsetsa, wotsika mtengo, ndizomwe zimagwiritsidwa ntchito kwambiri pazitsulo zopangira zipolopolo ku China, komanso chimodzi mwazinthu zomwe zingatheke kuti ziteteze zida zankhondo.

Kuchita bwino kwa zinthu za silicon carbide kumatha kupititsa patsogolo kukana kwa chipangizo choteteza. Silicon carbide ceramics palokha imakhala ndi mphamvu zambiri, kuuma kwakukulu, kukana kuvala kwambiri, kuchita bwino kwambiri (kuposa alumina zadothi, pafupifupi 70% -80% ya zoumba za boron carbide), mtengo wotsika ndi zina ndizoyenera kugwiritsa ntchito poletsa zipolopolo. chipangizo. Nthawi zambiri amagwiritsidwa ntchito m'makampani ankhondo zida zankhondo, zida zankhondo, zida zankhondo zamagalimoto ndi zida zina zoteteza; Makampani aboma amagwiritsidwanso ntchito ngati zida zoteteza magalimoto okhala ndi zida, zida zodzitetezera, ndi zina.

Silicon carbide ceramic zinthu zili ndi makina abwino kwambiri, matenthedwe, mankhwala komanso thupi, ndipo ali ndi malo okulirapo pantchito yoteteza zida. M'zaka zaposachedwa, zida za silicon carbide ceramic bulletproof zida zakhala zikugwiritsidwa ntchito kwambiri poteteza zida zankhondo, monga zida zankhondo, nsanja ya zida zankhondo, mfuti ndi apolisi, magalimoto apadera aboma. Kuphatikiza apo, kugwiritsa ntchito silicon carbide mu semiconductor, mphamvu ya nyukiliya ndi magawo ena apamwamba kwambiri kukukulirakulira, chiyembekezo chogwiritsa ntchito ndi chotakata kwambiri.
