Tantalum carbide ufa, TaC

Kukhazikika kwazopeka ndi 1.44, malo osungunuka ndi 3730-3830 ° C, koyefishienti kakukula kwamatenthedwe ndi 8.3 × 10-6, zotanuka modulus ndi 291GPa, koyefishienti yamagetsi yamagetsi ndi 0.22j / cm · S · C.
Makhalidwe ndi NTCHITO
Kukhazikika kwamakina abwino, osasungunuka ndi zidulo. Mphamvu yamphamvu ya antioxidant. TaC nthawi zambiri imapangidwa kuchokera ku tantalum pentoxide ndi mpweya wakuda mumlengalenga kapena mumlengalenga kuti mupange ufa wamkuwa.

Chikhalidwe cha
Kuwala kofiira kansalu kansalu kakang'ono kofiira, ndi kachitidwe ka sodium chloride cubic crystal. Zosasungunuka m'madzi, zosasungunuka m'matumba osakanikirana, zosungunuka m'mitundu yosakanikirana ya hydrofluoric ndi nitric acid ndikusungunuka pakuwonongeka. Amphamvu makutidwe ndi okosijeni, zosavuta kuti anasakaniza ndi kuwonongeka ndi potaziyamu pyrosulfate. Madutsidwe amagetsi ndi akulu, ali ndi 30 Ω kukana kutentha, kutentha kwambiri.
gwiritsani
Amagwiritsidwa ntchito popangira zitsulo, zida zodulira, ziwiya zadothi zabwino, kuyika kwa nthunzi ya mankhwala, zida zolimba zosavomerezeka za aloyi, zida, amatha kuumba komanso kuvala zowonjezera zowonjezera zowonjezera, kukonza kulimba kwa aloyi. Thupi losungunuka la tantalum carbide likuwonetsa utoto wagolide ndipo ukhoza kugwiritsidwa ntchito ngati chokongoletsera cha ulonda. Tantalum carbide sintered grain grow inhibitor imagwiritsidwanso ntchito poletsa kukula kwa tirigu, wokhala ndi 14.3g / cm3.

Tantalum carbide ndi hafnium carbide zonse ndi zaukadaulo wopanga, kutanthauza kuti zida ziwirizi zimakhala ndi kutentha kwapadera kwa zinthu ziwirizi ndikutha kulolera chilengedwe, kugwiritsa ntchito njira zomwe zikuyenera kuphatikizira kuthamanga kwambiri kwa shuttle's makina otetezera matenthedwe, komanso mafuta oyatsira magetsi anyukiliya okhala ndi malo otentha kwambiri, komabe, popeza sanayambebe kuonekera mu labu amatha kuyesa kusungunuka kwa TaC ndi HfC kwamitundu iwiri ya ukadaulo wa ceramic, zimapangitsa anthu kukhala osatsimikiza, kaya Kufikira izi, ofufuza apanga mtundu watsopano waukadaulo wowonjezera kutentha, pogwiritsa ntchito laser kuyesa kutentha kwa TaC ndi HfC pogwiritsa ntchito njirayi, ofufuzawo adazindikira kuti TaC ndi HfC onse ndi oyambira komanso kusungunuka kwa chisakanizo chomwe kafukufukuyu watulutsa posachedwapa mu

Magazini a Scientific Reports (Scientific Reports), adapeza kuti kusakanikirana kwa mitundu iwiri ya ceramic (Ta0.8 H2O20C) ya malo osungunuka omwe amawoneka mogwirizana ndi zotsatira zam'mbuyomu, kudafika $ 3905, koma kusungunuka kwa mankhwala awiriwa ndikokwera kuposa Malo osungunuka kale aTaC adafika $ 3768, pomwe HfC ndi 3958, ofufuzawo adati kupezeka kwa mitundu iwiriyi yazinthu, kudzatsegulira njira mbadwo wotsatira wa chitukuko cha magalimoto oyendetsa ndege zomwe zikutanthauza kuti ndege zamtsogolo zitha kuthamanga kwambiri kuposa kale, kuphunzira anali Omar, sadie LouSi, Mr Barak (Omar Cedillos Barraza) Dr Mu department of fizikiya ku koleji yachifumu ku London, pa PhD ya sadie LouSi Mr Barak,

Dr Is pakadali pano ndi pulofesa ku yunivesite ya Texas ku el paso, sadie LouSi, Mr Barak, "adatero Dr. Pouluka mothamanga mopitilira Mach 5, kusamvana ndi mpweya kumapangitsa kutentha kwakukulu. TaC kapena HfC sizinachitike akhala akugwiritsidwa ntchito popanga magalimoto mpaka pano, koma zomwe tapeza zatsopano zikusonyeza kutiThan timaganiza kuti mitundu iwiriyi yazinthu zotenthetsera, chifukwa chake zimatenthetsa magwiridwe antchito zinali zopitilira mankhwala ena onse odziwika kwa munthu zikutanthauza kuti chifukwa kapena itha kugwiritsidwa ntchito pa ndege yatsopano: mumlengalenga, chombo chanyanja chitha kukhala ngati ndege wamba, ndiye kuti danga lothamanga kwambiri ngati izi zingapangitse kuti ndegeyo izitha kuyendayenda pakati pa Kutentha kwakukulu komwe kumachitika chifukwa cha TaC komanso kugwiritsidwa ntchito kwa HfC ndi kapu ya ndege ndi kukangana ndi dziko lakunja zida zazikulu zakunja panthawi yakunyamuka Pakadali pano, chombo cha Mach 5 sichitha kuthawa, koma Dr. Cediloth

Baraza akunena kuti malotowo atha kukwaniritsidwa mtsogolo. Dr. Cediloth Baraza akuwonjezera kuti:
Mayeso athu akuwonetsa kuti kupanga kwa chombo chamtsogolo mlengalenga, mitundu iwiriyi yazinthu zili ndi kuthekera kwakukulu kwamitundu iwiriyi yazinthu zopirira kutentha kotere, izi zikutanthauza kuti tsiku lina mtsogolomo, ndege zokhala ndi hypersonic zilidi zotheka ngati titha kuwuluka pa liwiro la Mach 5, ndiye kuti nthawi yoti tichoke ku London kupita ku Sydney imafunikira mphindi pafupifupi 50 zokha, izi zibweretsa dziko lapansi kutseguka limapatsa pakati mwayi wapabizinesi wapadziko lonse lapansi.
