yini i-tantalum carbide

I-Tantalum carbide (TaC)iyi-ultra-high heat ye-ceramic material enokumelana nokushisa okuphezulu, ukuminyana okuphezulu, ukubumbana okuphezulu; ukuhlanzeka okuphezulu, okuqukethwe okungcolile <5PPM; kanye nokungangeni kwamakhemikhali ku-ammonia ne-hydrogen emazingeni okushisa aphezulu, nokuzinza okuhle kokushisa.

Okubizwa ngokuthi ama-ceramics okushisa aphezulu kakhulu (ama-UHTC) ngokuvamile abhekisela ekilasini lezinto zobumba ezinephuzu lokuncibilika elingaphezu kuka-3000 ℃ futhi elisetshenziswa emazingeni okushisa aphezulu nasezindaweni ezigqwalile (njengezindawo ze-athomu yomoya-mpilo) ngaphezu kuka-2000 ℃, njenge. ZrC, HfC, TaC, HfB2, ZrB2, HfN, njll.

I-Tantalum carbideinendawo yokuncibilika efika ku-3880℃, inobulukhuni obuphezulu (Mohs hardness 9-10), i-thermal conductivity enkulu (22W·m-1·K-1), amandla amakhulu okugoba (340-400MPa), kanye ne-coefficient encane yokwandisa ukushisa (6.6×10-6K-1), futhi ikhombisa ukuzinza okuhle kakhulu kwe-thermochemical kanye nezakhiwo ezinhle kakhulu zomzimba. Inokuhambisana okuhle kwamakhemikhali nokuhambisana kwemishini nama-graphite kanye nezinhlanganisela ze-C/C. Ngakho-ke,I-TaC coatingsasetshenziswa kakhulu ekuvikelweni okushisayo kwe-aerospace, ukukhula kwekristalu eyodwa, ama-electronics wamandla, namadivayisi wezokwelapha.

I-Tantalum carbide (TaC)uyilungu lomndeni we-ceramic wokushisa okushisa kakhulu!

Njengoba izindiza zesimanje njengezimoto zasemkhathini, amarokhethi, nemicibisholo ejikijelwayo ithuthuka ibheke ngesivinini esikhulu, i-thrust ephezulu, kanye nokuphakama okuphezulu, izidingo zokumelana nezinga lokushisa eliphezulu nokumelana ne-oxidation yezinto ezingaphezulu ngaphansi kwezimo ezimbi kakhulu ziya ngokuya ziba phezulu. Uma indiza ingena emkhathini, ibhekana nezimo eziyingozi kakhulu ezifana nokuminyana kokushisa okuphezulu, ukucindezela kokuma okuphezulu, nesivinini esisheshayo sokugeleza komoya, kanye nokukhishwa kwamakhemikhali okubangelwa ukusabela komoyampilo, umhwamuko, nesikhutha. Lapho indiza indiza iphuma futhi iye emkhathini, umoya ozungeze ikhala layo namaphiko uyocindezelwa kakhulu futhi ukhiqize ukungqubuzana okukhulu nobuso bendiza, okubangela ukuthi indawo yayo ifudumale ngokugeleza komoya. Ngaphezu kokushiselwa emoyeni ngesikhathi sokundiza, ingaphezulu lendiza lizophinde lithinteke ngemisebe yelanga, imisebe yemvelo, njll. phakathi nokundiza, okubangela ukuthi izinga lokushisa elingaphezulu lendiza liqhubeke nokukhuphuka. Lolu shintsho luzothinta kakhulu isimo sesevisi yendiza.

I-Tantalum carbide powder iyilungu lomndeni we-ceramic omelana nokushisa okuphezulu kakhulu. Iphuzu layo eliphezulu lokuncibilika kanye nokuzinza okuhle kakhulu kwe-thermodynamic kwenza i-TaC isetshenziswe kabanzi ekugcineni okushisayo kwendiza, isibonelo, ingavikela uqweqwe olungaphezulu lombhobho wenjini yerokhethi.
