Li-cubic Silicon Carbide Whiskerske litelu tse matla tse nang le litelu tse bōpehileng joaloka monolithic (one-dimensional), tse nang le mekhoa e mengata e babatsehang ea mechine e kang matla a phahameng le mehlala e phahameng.E sebelisoa haholo linthong tse entsoeng ka tšepe le tse entsoeng ka ceramic.E sebelisoa haholo-holo likarolong tse phahameng tsa mocheso tšimong ea lisebelisoa tsa ceramic, tšimo ea sebaka, ho beha, lipompo tse kholo tsa seretse, joalo-joalo.
Litšobotsi tsa 'mele: Ke mofuta oa kristale oa cubic, e leng mofuta oa kristale o ts'oanang le taemane.
Litšobotsi tsa lik'hemik'hale: anti-wear, ho hanyetsa mocheso o phahameng, haholo-holo ho hanyetsa mocheso, ho hanyetsa kutu, ho hanyetsa mahlaseli.
Kopo: boleng bo phahameng ba ceramic bearing, hlobo, ho thunngoa ha matla a phahameng, ho hanyetsa mocheso o phahameng, joalo-joalo.
Silicon carbide e na le sebopeho sa kristale ea daemane.Sena se bakoa ke likarolo tsa carbon le silicon tse etsang li-SiCs.Ke karolo ea SP element ea IVA tafoleng ea potoloho ea element.Ha likarolo tsena li theha likristale Botsitso bo boholo ba SP3 bo hlophisitsoe, ho na le senotlolo se tiileng sa covalent, litšobotsi tse tloaelehileng tsa theko le matla a phahameng a senotlolo, ho etsa qeto ea hore silicon carbide e na le matla a itseng le matla a mochine.Ho thatafala ha SIC's MOBS ho fihlile 9.5, ea bobeli ho latela daemane.Litelu tsa Cubic SiC li na le ho thatafala ho hoholo, modulus, matla a tsitsitseng le ho hanyetsa mocheso o phahameng ho feta lisebelisoa tse ling tsa litelu.
Litelu tsa SiC li ka aroloa ka ho lekana 'meleng o teteaneng e le likaroloana tsa karolo ea bobeli, tse ka tsamaisanang le' mele hantle.Ka mor'a hore mocheso o phahameng o thehoe, hobane motsoako oa ho atolosa mocheso oa kristale le thepa ea 'mele o fapane, kristale le sebopeho sa' mele oa sebopeho sa 'mele Ka mor'a hore khatello ea kelello e eketsehileng e hlahisoe, ka mor'a hore thepa e kopantsoeng e fokotsehe hanyenyane, khatello ea kelello ea ho phatloha. pheletso e fetela ho sebopeho sa kristale le matrix.Ho monya khatello ea maikutlo kantle.Ka tsela ena, litelu tsa SiC li ka thibela ho ata ha "micro-cracks" ka "bridge couplet", "crack deflection", "crystal pull out effects" le "broken crystal effects", ka tsela eo e matlafatsa le ho matlafatsa 'mele oa' mele.Thepa e kopantsoeng e na le boima bo phahameng le thepa ea mechine.Hobane likristale tsa SIC li tlameha ho ba le botsitso bo botle mochesong o phahameng, lisebelisoa tsa eona tse ntlafalitsoeng le tse thata tse kopaneng li ntse li ka boloka thepa e ntle ea mochini ha 1000 ° C kaholimo ho 1000 ° C.
Li-cubic Silicon Carbide Whiskerse ka sebelisoa e le lisebelisoa tse ntlafalitsoeng ka matrix a polasetiki, matrix a tšepe kapa substrate ea ceramic ho matlafatsa le ho matlafatsa.Tataiso e phahameng ea mocheso, ho kenya lisebelisoa tse phahameng tsa SIC, li-substrates bakeng sa lipotoloho tse kholo tse kopaneng indastering ea lisebelisoa tsa elektroniki le lisebelisoa tse Packaged.Joalo ka lisebelisoa tsa optical tsa tlhahisoleseling, e na le boleng bo phahameng ba ts'ebeliso masimong a ponts'o ea TV, puisano ea sejoale-joale le marang-rang.
Litelu tsa carbonic silicon carbide ke lisebelisoa tse ntlafatsang haholo bakeng sa tšepe, ceramic le polymer polymer base composite.
