Tantalum carbide (TaC)ndeye Ultra-yakakwirira tembiricha ceramic zvinhu zvine tembiricha kuramba, yakakwirira density, yakakwirira compactness; kuchena kwepamusoro, kusvibiswa kwemukati <5PPM; uye makemikari inertness kuti ammonia uye haidrojeni panguva yakakwirira tembiricha, uye zvakanaka kupisa kugadzikana.
Iyo inonzi ultra-high tembiricha ceramics (UHTCs) inowanzo reva kirasi yezvigadzirwa zveceramic ine nzvimbo yekunyunguduka inodarika 3000 ℃ uye inoshandiswa mukupisa kwakanyanya uye nzvimbo dzinotyisa (senge oksijeni atomic nharaunda) pamusoro pe2000 ℃, senge. ZrC, HfC, TaC, HfB2, ZrB2, HfN, nezvimwewo.
Tantalum carbideine nzvimbo yekunyunguduka inosvika 3880 ℃, ine kuomarara kwakanyanya (Mohs kuomarara 9-10), hombe yekupisa conductivity (22W · m-1 · K-1), hombe yekukotama simba (340-400MPa), uye diki yekuwedzera kupisa kwekuwedzera (6.6 × 10-6K-1), uye inoratidza yakanakisa thermochemical kugadzikana uye zvakanakisa zvemuviri zvimiro. Iyo ine yakanaka kuenderana kwemakemikari uye mechanical kuenderana negraphite uye C / C composites. Naizvozvo,TaC coatingsanoshandiswa zvakanyanya muaerospace thermal protection, single crystal kukura, magetsi emagetsi, uye midziyo yekurapa.
Tantalum carbide (TaC)inhengo ye-ultra-high tembiricha yeceramic mhuri!
Sezvo ndege dzemazuvano dzakaita semotokari dzemuchadenga, maroketi, uye zvombo zvinokandwa zvichikura kusvika pakumhanya kukuru, kurovera kwakakwirira, uye kukwira kumusoro, zvinodikanwa zvekudzivirira kwekushisa kwakanyanya uye kushorwa kweoxidation yezvinhu zvavo zvepasi pasi pemamiriro akanyanya kukwira. Kana ndege ichipinda mumhepo, inotarisana nemhoteredzo dzakanyanyisa dzakadai seyakanyanya kupisa kuyerera, kusimba kwekumira, uye kukurumidza kufefetera kwemhepo, pamwe nekubvisa kemikari kunokonzerwa nekuita neokisijeni, mhute yemvura, uye carbon dioxide. Kana ndege ichibhururuka ichibuda ichipinda muchadenga, mhepo yakatenderedza mhuno nemapapiro ayo inomanikidzwa zvakanyanya uye ichaita kukwesha kukuru nepamusoro pendege, zvichiita kuti pamusoro payo ripiswe nemhepo. Pamusoro pekudziya kweaerodynamic panguva yekubhururuka, pamusoro pendege ichakanganiswawo nemwaranzi yezuva, mwaranzi yezvakatipoteredza, nezvimwewo panguva yekubhururuka, zvichiita kuti kupisa kwepasi kwendege kurambe kuchikwira. Shanduko iyi ichakanganisa zvakanyanya mamiriro ebasa rendege.
Tantalum carbide poda inhengo ye-ultra-high tembiricha inodzivirira ceramic mhuri. Iyo yakakwira yekunyungudika uye yakanakisa thermodynamic kugadzikana inoita kuti TaC ishandiswe zvakanyanya mukupisa kunopisa kwendege, semuenzaniso, inogona kuchengetedza iyo yekuputira pamusoro peiyo roketi injini nozzle.
