I-Sintered silicon carbide ceramics kanye nochungechunge lomkhiqizo we-silicon carbide ceramic bulletproof

I-Sintered SiC Ceramics: Izinzuzo ze-SiC Ceramic Ballistic Products

Imikhiqizo ye-silicon carbide ceramic bulletproofziya ngokuya zithandwa kakhulu emkhakheni wokuvikelwa komuntu siqu nezempi ngenxa yokusebenza kwazo okuhle nokusebenza kwazo. Lawa ma-ceramics anokuqukethwe kwe-SiC ≥99% nokuqina (HV0.5) ≥2600, okuwenza abe yimpahla yokuzikhethela yezinhlelo zokusebenza ze-ballistic ezifana namavesti angangenwa izinhlamvu kanye namagiya okuvikela amathangi nezimoto zezikhali.

Umkhiqizo oyinhloko walolu chungechunge i-silicon carbide ceramic bulletproof sheet. Ukuminyana kwayo okuphansi nesisindo esilula kuyenza ifaneleke kakhulu ezintweni ezivikela izinhlamvu zesosha ngalinye, ikakhulukazi njengolwelwesi lwangaphakathi lwamavesti angangenwa izinhlamvu. Ngaphezu kwalokho, inikeza izinzuzo ezibalulekile mayelana nokuqina, amandla kanye nokuzinza kwe-thermal.

I-silicon carbide (SiC) ceramics inezinhlaka ezimbili zekristalu, i-cubic β-SiC kanye ne-hexagonal α-SiC. Lezi zobumba zinezibopho eziqinile eziqinile, izakhiwo ezingcono zemishini, ukumelana ne-oxidation, ukumelana nokugqoka kanye ne-coefficient ephansi yokungqubuzana kunezinye izitsha zobumba ezifana ne-alumina ne-boron carbide. I-thermal conductivity ephezulu, i-coefficient encane yokunwetshwa kokushisa, kanye nokumelana okuhle nokushaqeka okushisayo nokugqwala kwamakhemikhali kuqhubekisela phambili ukusetshenziswa kwazo okubanzi.

Umgomo we-bulletproof we-silicon carbide ceramics usekhonweni layo lokuhlakaza nokumunca amandla enhlamvu. Ngenkathi izinto zobunjiniyela bendabuko zidonsa amandla ngokuguqulwa kwepulasitiki, izinto zobumba, kufaka phakathi i-silicon carbide, zenza kanjalo ngama-microfractures.

Inqubo yokumuncwa kwamandla ye-silicon carbide bulletproof ceramics ingahlukaniswa izigaba ezintathu. Phakathi nesigaba sokuqala somthelela, inhlamvu ishaya i-ceramic surface, ithuntubeze inhlamvu futhi igxobe i-ceramic surface, idale izindawo ezincane ezihlukene eziqinile. Phakathi nesigaba sokuguguleka, inhlamvu ebuthuntu iyaqhubeka nokuguguleka indawo yemfucumfucu, yakha ungqimba oluqhubekayo lwemfucumfucu yobumba. Ekugcineni, phakathi nezigaba ze-deformation, crack and fracture, i-ceramic ibhekana nokucindezeleka okuqinile, okuholela ekuqhekekeni kwayo ekugcineni. Amandla asele abe esehlakazwa yi-deformation ye-backplate material.

Lezi zakhiwo ezinhle kakhulu kanye nenqubo yokumunca amandla enezigaba ezintathu inika amandla imikhiqizo ye-silicon carbide ceramic ballistic ukuthi inciphise ngempumelelo umthelela wezinhlamvu futhi izenze zingabi nangozi. Isilinganiso sokuvikela inhlamvu sifinyelela ezingeni lesi-4 elijwayelekile laseMelika, elihlinzeka ngokuvikeleka okuphezulu futhi ukukhetha kokuqala kochwepheshe bezempi emhlabeni.

Ukufingqa, uchungechunge lomkhiqizo we-silicon carbide Ceramic bulletproof lunezinzuzo ezihlukile mayelana nezakhiwo zemishini, ukuqina okushisayo, nokusebenza kahle kokuvikela izinhlamvu. Ngezakhiwo zabo eziphakeme, lezi zobumba zisetshenziswa kabanzi njengezinto zokwenziwa kolwelwesi lwama-bulletproof vest kanye nemishini yokuvikela amathangi nezimoto ezihlomile. Ukuminyana kwazo okuphansi nesisindo esilula kuzenza zilungele ukuvikelwa komuntu siqu kwe-ballistic. Njengoba ubuchwepheshe buqhubeka buthuthuka, singalindela okunye ukuthuthuka nokusetshenziswa kwalezi zitsha zobumba eziphawulekayo ekuvikelweni komuntu siqu nezempi.
