M'zaka zaposachedwa, wasayansi wazipangizo adapanga kalasi yatsopano yazinthu 312 zamtundu wa ceramic, kapangidwe kake ka M3XZ2, pakati pawo, M ndi chimodzi mwazinthu zingapo zosinthira (monga Ti, V), X ndi chimodzi kapena zingapo Mwa zinthu zikuluzikulu zotsatirazi, zingapo za III, IV zamagulu akulu (monga Al Ge Si), Z ndichimodzi kapena zingapo zopanda malire (monga CNB, ndi zina), pali 312 zogonana zophunzira za ternary Kapangidwe ka Ti3SiC2 chachikulu Ti3AlC2 Ti3GeC2 ali ndi mawonekedwe ofanana a kristalo, omwe ali pafupi / MMC gulu lamagulu Oyimira magulu awa ndi omwe Ti3SiC2 ndiyotayirira Ti3SiC2 ceramic zakuthupi za Titanium silicon carbide Ti3SiC2 (Titanium silicon carbide) ndi mtundu wa zinthu zopangidwa ndi ceramic. magwiridwe antchito a kukana kutentha kwakutentha kwamphamvu kwamphamvu, komanso zida zachitsulo monga kusunthika kwamatenthedwe otenthetsera komanso mwayi wopanga zida za pulasitiki mu 1980 s, pafupifupi chifukwa cha kufulumira kwake kugwiritsira ntchito wothandizira monga fiber, ndevu ndi ndege zapamwamba zolemekezedwa kuposa zofunikira za injini, ceramic matrix composites imakhala malo otentha ofufuzaBy CHIKWANGWANI, whisker kumawonjezera kulimba kwake kumawoneka bwino, koma chifukwa chakukonzekera mtengo wokwera komanso kudalirika kochepa , zikadali zovuta kuyika kuti athetse vutoli ofufuzawo adayamba kuwona momwe zinthu zonse zachitsulo komanso zadothi zotentha kwambiri, zomwe zimapezeka mu Ti-Si-C system ya titanium silicon carbide Ti3SiC2 (Ti3SiC2) ili ndi mawonekedwe onsewa chitsulo kutentha kutentha ndi kutentha kwabwino kwamagetsi ndi magwiridwe amagetsi, kuwuma kotsika kotsika ndi kukhathamira kwakukulu; Ductile kutentha, amatha kusinthidwa ngati chitsulo, ndi pulasitiki kutentha kwambiri; Nthawi yomweyo, imakhala ndi katundu Zipangizo za ceramic, mphamvu zokolola zambiri, malo osungunuka kwambiri, kukhazikika kwamatenthedwe komanso kukana makutidwe ndi okosijeni abwino. Ikhoza kukhalabe ndi mphamvu yayikulu kutentha. Chofunika kwambiri ndikuti imakhala ndi magwiridwe antchito otsika komanso otsika bwino kuposa mafuta amtundu wolimba.
Kuyambira mu Disembala 2005, Unduna wa Sayansi ndi Ukadaulo mdziko lathu wapereka uthenga wamphamvu: umodzi wokhala ndi ufulu wodziyimira pawokha, Ti3SiC2 yopanga ceramic m'badwo watsopano wa pulogalamu yothamanga kwambiri ya sitimayi mu pulogalamu ya 863 , ntchito zantchito zomanga bwino, zopangidwa ndi ndalama kuchokera ku projekiti yopanga yunivesite ya Beijing jiaotong patadutsa zaka ziwiri motsatizana kuti agonjetse kuyera kwambiri kwa Ti3SiC2, Ti3AlC2, Ti2SnC ceramic powder bulk synthesis technology, skateboard kupanga ndondomeko, kuti amalize kuphunzira zakuthupi ndi mankhwala, skateboarding potsegula mayeso othamanga. The Ti3SiC2 mndandanda ceramic skateboards opangidwa mwaluso ndi gulu lofufuzirali akuwonetsedwa ndi madutsidwe apamwamba, kukana kukana, kukana kumva kuwawa, arc ablation kukana, kutsika pang'ono kwa waya wolumikizana, ndi zina, kuthana bwino ndi mavuto monga kumva kuwawa kaboni kutengera ufa skateboards zitsulo ntchito kunyumba ndi kunja, zosavuta kuswa, ndi kuwonongeka kwa waya kukhudzana. Ti3SiC2 ma cate skateboards opangidwa bwino mchaka chimenecho adachita gawo lofunikira pakukonza njanji zothamanga ku China.Ii. Katundu wamkulu wa Ti3SiC2 magawo a ceramic
Ti3SiC2 imaphatikiza katundu wa ziwiya zadothi ndi zitsulo. Kutulutsa kwake kotupa kwambiri, malo osungunuka komanso kutentha kwambiri kumawonekeranso ngati zida za ceramic. Kutulutsa kwakukulu, modulus yokwera kwambiri, malo osungunuka komanso kutentha kwambiri kumawonetsera mawonekedwe ake ofanana ndi a ceramic.
Gulu 1. Katundu Wamkulu wa ziwiya zoumbaumba za Ti3SiC2 (Kutentha kwapakati)
Kafukufuku wokhudzana ndi kuwonongeka kwa Ti3SiC2 akuwonetsa kuti pali kuwonongeka kwakukulu kwachinyengo
woyang'aniridwa ndi Ti3SiC2. Chifukwa chake ndi chakuti Ti3SiC2 ili ndi zida zamagetsi zingapo zomwe zimayambira pakuwonongeka, monga kufalikira kwa microcrack, kuphulika kwa tirigu, kutulutsa tirigu, kukhotetsa tirigu, ndi zina zambiri. Zinthu zamtunduwu zimakhala ndi chiyembekezo chazambiri zakapangidwe kakutentha, zida zamagetsi zamagetsi, zopangira mafuta, zopangira kutentha ndi zina zotero. Komabe, kuuma kotsika, kuvala kukana ndi makutidwe ndi okosijeni kukana kwa zida za ceramic kumachepetsa magwiritsidwe ake munthawi zovuta monga kukana kutopa, kuvala kukana ndi kukaniza makutidwe ndi okosijeni. Kugwiritsa ntchito zida za ceramic za Ti3SiC2
(I) Ntchito zachilengedwe
M'mano opangira mano, zida kapena zinthu zomwe zimagwiritsidwa ntchito pakamwa pamafunika kuti zizikhala zokhazikika komanso zosunthika kwakanthawi kwakanthawi chifukwa cha makutidwe ndi okosijeni. Ti3SiC2 ili ndi zinthu zonse za ceramic ndi chitsulo komanso kusakanikirana kwabwino, zomwe zimapangitsa kuti zizigwiritsidwa ntchito m'thupi la munthu. Ti3SiC2 imatha kusinthidwa kukhala ulusi wa kukula kwake popanda chopangira mafuta, motero imatha kupangidwa kukhala amadzala kapena ma prosthetics ogwiritsira ntchito kuchipatala mu stomatology. Modulus yotsekemera ya Ti3SiC2 ili pafupi ndi enamel kapena dentin kuposa zirconia (1.9 × 105MPa), ndikuwonjezera kuthekera kwake kolemba kapena korona wamkati wa ceramic. Zipangizo za Ti3SiC2 zochokera pazodzikongoletsa zodzipangira zokha zimakhala ndi minyewa yolusa yomwe ingakhale yosavuta kupanga ndikumangirira. Kulephera kotsutsana pang'ono kumapangitsa kuti kuyika kwa orthodontics kukulitsa kutsika ndikuchepetsa kukangana.
Kukana kwa dzimbiri komanso kukana makutidwe ndi okosijeni ndizofunikira pakugwiritsa ntchito izi m'kamwa komanso kukhazikika kwake. Izi ndizopaka ufa ndi zinthu zonse za ceramic, ndipo digiri yawo yomanga ikhoza kukhala yabwinoko kuposa yachitsulo ndi zadothi. Chifukwa chake, magwiritsidwe ntchito amtunduwu atha kukhala wokulirapo pamutu wamkati wa ceramic.
Komabe, njira yodziwikiratu yomwe ikupezeka ya Ti3SiC2, njira yokonzekera iyenera kukonzedwa bwino kuti itenge zotchinga za Ti3SiC2, kuti mumvetse bwino za zinthuzo. Maphunziro owonjezera a labotale ndi zamankhwala amafunikira kuti atsimikizire kusakanikirana komanso kuthekera kwa zinthuzo.
Ndi kutchuka kwa ukadaulo wowotchera mwachangu mumakampani a ceramic, kagwiritsidwe ntchito ka mipando yamoto ikuchepera ndipo magwiritsidwe ntchito ndi ovuta kwambiri. Chifukwa chake, ndikofunikira kupititsa patsogolo kukana kwamphamvu kwa zida zam'nyumba kuti zikwaniritse zosowa zaukadaulo wofulumira m'makampani a ceramic.
Monga mtundu wa mafakitale apamwamba, mipando yamoto imakhudza kwambiri zinthu zomwe zimawotchedwa. Zoumbaumba za Ti3SiC2 sizimvetsetsa kutentha kwa matenthedwe, mawonekedwe ake apadera komanso mawonekedwe apulasitiki pamatentha otentha amatha kuchepetsa kukhathamira kwamphamvu.
Zinthu zakuthupi kudzera △ T = 1400 shock matenthedwe amphamvu zotsalira akadali pamwambapa 300MPa, magwiridwe antchito osagwedezeka kwambiri amatha kupirira kusiyana kwa kutentha kwa 900.. Nthawi yomweyo, ziwiya zadothi za Ti3SiC2 zili ndi zabwino zotsutsana ndi mankhwala, kukonza kosavuta komanso mtengo wotsika wa zopangira, ndikupangitsa kuti ukhale chida choyenera cha uvuni.
