Lefapheng la ts'ireletso ea sejoale-joale, ka ntlafatso e tsoelang pele ea matla a libetsa, litlhoko tsa lisebelisoa tse thibelang likulo li ntse li eketseha.Silicon carbide, ntho e bonahalang e tloaelehile empa e le matla haholo, butle-butle e hlaha e le ntho e ncha e ratoang indastering e thibelang likulo. Kajeno, re tla senola lesira le makatsang la silicon carbide bulletproof.
1. Ho senola molao-motheo o thibelang likulo
Sepheo sa tšireletso ea lihlomo ke ho sebelisa matla a projectiles, ho li fokotsa ho fihlela li lahleheloa ke kotsi ea tsona. Lisebelisoa tsa tšepe tsa setso li itšetlehile ka deformation ea polasetiki ho monya matla, ha lisebelisoa tsa ceramic li finyella pakane ena ka mokhoa o ikhethang oa ho senya. Ho nka mohlala oa li-ceramics tsa silicon carbide bulletproof, ha projectile e ama projeke, projectile e qala ho ba lerootho hang-hang holim'a tšusumetso, 'me bokaholimo ba ceramic bo a pshatleha ho etsa sebaka se arohaneng se thata. Ts'ebetso ena e tšoana le ho fa projectile "hamore" 'me qalong e monya matla; Joale, projectile e hlabang e ile ea tsoela pele ho tsoela pele, e senya sebaka se arohaneng 'me e etsa lera le tsoelang pele la likhechana tsa ceramic; Qetellong, fractures ea ceramic tlas'a khatello e matla, 'me mokokotlo o qala ho senyeha. Matla a setseng a kenngoa ka ho feletseng ke ho senyeha ha thepa ea mokokotlo.
2. Ke hobane'ng ha silicon carbide e ka ba bulletproof?
Silicon carbide ke motsoako o entsoeng haholo ka li-covalent bond, 'me li-bond tsa eona tsa Si-C li ka boloka matla a phahameng mochesong o phahameng. Sebopeho sena se ikhethang se fana ka li-ceramics tsa silicon carbide tse nang le thepa e ngata e babatsehang. E na le boima bo phahameng haholo, ea bobeli ho daemane, cubic boron nitride, le boron carbide har'a lisebelisoa tse tloaelehileng. E tšoana le mohlabani ea apereng lihlomo tse thata, ea khonang ho hanyetsa ka matla tšusumetso ea projectile; Ka nako e ts'oanang, e na le boima bo fokolang 'me e boima bo bobebe ha e etsoa thepa e thibelang likulo. Ebang ke bakeng sa ntoa ea motho ka mong kapa e nang le likoloi le lifofane, e ke ke ea e-ba moroalo o eketsehileng, empa ho e-na le hoo e ka ntlafatsa ho tsamaea ha lihlopha tsa ntoa. Ntle le moo, silicon carbide e boetse e na le botsitso bo botle ba mocheso le k'hemik'hale ea kutu ea lik'hemik'hale, 'me e ka bapala karolo e thibelang likulo ka mokhoa o tsitsitseng libakeng tse fapaneng tse rarahaneng.
3, Melemo e ikhethang ea karabelo sintered silicon carbide ka likarolo tse ikhethileng
Ha ho etsoa li-ceramics tsa silicon carbide, reaction sintered silicon carbide (RBSiC) ea hlahella, haholo-holo e loketseng tlhahiso ea karolo e ikhethileng, ka mabaka a latelang:
1. Boima bo phahameng le matla a phahameng: Tlas'a maemo a phahameng a mocheso, carbon e sa lefelloeng e sebetsana le silicon ea metsi ho hlahisa likristale tse ncha tsa silicon carbide. Ka nako e ts'oanang, silicon e sa lefelloeng e phunyeletsa 'me e tlatsa li-pores, e eketsa haholo ho teteana ha thepa, hoo e batlang e atamela ho teteaneng ea theory. Sena ha se fane feela ka thepa e nang le matla a matla a ho hatella le ho kobeha, empa hape se e fa khanyetso e ntle ea ho roala, e ka mamellang khatello e phahameng le maemo a ts'usumetso e phahameng, ho fihlela litlhoko tse tiileng tsa likarolo tse hlophisitsoeng bakeng sa matla le ho tšoarella.
2. Laoleha microstructure: The karabelo sintering tshebetso ka nepo laola kgolo ya lijo-thollo, ho etsa tse nyenyane le junifomo microstructures. Microstructure ena e ntle e ntlafatsa ka ho eketsehileng thepa ea mechine ea thepa, e etsa hore e lule e tsitsitse 'me e se ke ea senya kapa e senya ha e tobane le likhatello tse sa tšoaneng tse rarahaneng, ho fana ka tiiso e tiileng bakeng sa ho tšepahala ha likarolo tse hlophisitsoeng.
3. Ho nepahala ha boemo bo phahameng: Nakong ea ts'ebetso ea densification, liphetoho tse fapaneng tsa karabelo sintered silicon carbide li nyane, e leng tsa bohlokoa bakeng sa likarolo tse ikhethileng. Ebang ke polaka e le 'ngoe e thibelang likulo ea lesole e nang le libopeho tse rarahaneng kapa karolo e khethehileng ea tšireletso ea koloi e nang le litlhoko tse tiileng tsa boholo, li ka etsoa ka nepo ho netefatsa hore li lumellana hantle le lisebelisoa.
4. Botsitso bo botle ba lik'hemik'hale: Reaction sintered silicon carbide e batla e se na li-pores tse bulehileng, e etsang hore ho be thata hore oksijene le lintho tse senyang li kenelle ka hare ho thepa, kahoo li na le oxidation e matla ka ho fetisisa le ho hanyetsa ho bola. Sena se bolela hore lihlahisoa tsa li-bulletproof tsa silicon carbide li ntse li ka boloka ts'ebetso e tsitsitseng, ho lelefatsa bophelo ba ts'ebeletso, le ho fokotsa litšenyehelo tsa tlhokomelo libakeng tse thata tsa tlhaho kapa tsa lik'hemik'hale ka nako e telele.
4, Tšimo ea kopo ea silicon carbide bulletproof
Ka ts'ebetso ea eona e ntle haholo, lisebelisoa tsa silicon carbide bulletproof li sebelisitsoe haholo libakeng tse ngata:
1. Thepa ea motho ka mong: lesela la silicon carbide bulletproof vest, helmete e thibelang likulo, joalo-joalo, e fa masole tšireletso e bobebe le e phahameng, e ba lumellang ho loana ka mokhoa o feto-fetohang lebaleng la ntoa ha ba ntse ba e-na le tšireletso e tšepahalang ea tšireletso.
2. Likoloi tse khethehileng: tse kang likoloi tsa lihlomo, likoloi tsa lipalangoang tsa chelete, li-anti-terrorism le likoloi tsa ho laola merusu, joalo-joalo, li na le lihlomo tsa silicon carbide ceramic likarolong tsa bohlokoa, tse ka atlehang ho hanela litlhaselo tse sa tšoaneng tsa libetsa le ho sireletsa tšireletso ea basebetsi le lisebelisoa tsa bohlokoa ka hare ho koloi.
3. Sepakapaka: Thepa ea silicon carbide bulletproof e sebelisoa ho lihelikopthara tse hlometseng le lifofaneng tse ling ho fokotsa boima ba tsona, ho ntlafatsa ts'ebetso ea sefofane, le ho ntlafatsa bokhoni ba tsona ba ho itšireletsa khahlanong le mollo oa sera, ho netefatsa polokeho ea lifofane.
Ka tsoelopele e tsoelang pele ea theknoloji, lisebelisoa tsa silicon carbide bulletproof li tla tsoela pele ho nts'etsapele le ho nchafatsa, ho aha mohala o matla oa ts'ireletso bakeng sa ts'ireletso ea polokeho. Haeba u thahasella likarolo tse ikhethileng tsa karabelo sintered silicon carbide ceramics, ka kopo ikutloe u lokolohile ho ikopanya le rona.
