Whakapai ake i te Rohe Wera o te Umu Korehau Tiamana C/C Composite: Ārai-Huri me te Whakamāmā
Whakarāpopototanga Whakahaere
He rangahau take whakapai ake mō te oumu tinei hau pēhanga teitei Tiamana (1350°C / 20bar): I whakamahia e VET Energy ngā pūtu hiato C/C ritenga, ngā anga kawenga māmā, me ngā tokotoko whakamahana karāpeti kua pania ki te CVD SiC hei whakakapi i ngā wāhanga molybdenum tuku iho me te karāpeti taumaha. Nā tēnei i whakaoti katoa te totohu o te ngoki pāmahana teitei me ngā aukati pakaru pinepine. Te mahi i ine: kua heke te taumaha o te anga mā te 62%, kua piki ake te kaha kawenga kupenga mā te 35%, kua heke te whakapaunga pūngao kotahi-rōpū mā te 22%, kua roa ake te ora ratonga o ngā wāhanga neke atu i te 3x, ā, kua neke atu i te €22,000 ngā penapena utu ā-tau.
Kupu Whakataki
I roto i ngā tukanga tinei hau pēhanga teitei (HPGQ) me ngā tukanga whakawera pāmahana tino teitei, ko te mahi wera me te papatipu wera o ngā wāhanga matua o te rohe wera te mea e whakatau tika ana i te hua o ngā taputapu me te kounga tinei o ngā mea mahi. He maha ngā wā ka whakawhirinaki ngā oumu korehau tuku iho ki ngā taputapu molybdenum taumaha (Mo) me ngā taputapu karāpeti me ngā pūtu karāpeti paerewa. I raro i te huringa wera nui i te 1200°C–1400°C me ngā ru tinei hau kaha o te 10–20 pae, ka pāngia ēnei tatūnga tuku iho e te ngoki nui o te pāmahana teitei, te whati, me te pakaru waikura.
E whakamārama ana tēnei rangahau take i te āwhina a VET Energy i tētahi kiritaki maimoatanga wera Tiamana ki te wikitoria i te rerekētanga pāmahana tino teitei me ngā aukati nui o te whakapaunga pūngao mā te hanga i tētahi hanganga kaha teitei.Ngā pūtu hiato C/C, ngā anga kawenga mama maha-paparanga, meNgā tokotoko whakamahana karāhe kua pania ki te CVD SiC/TaC.

Te Horopaki Taupānga me ngā Wāhi Mamae o te Kiritaki
Ka mahi ngā tokotoko whakamahana karāpiti i roto i ngā oumu tinei hau korehau i te 1350°C. I te wā tinei hau pēhanga teitei, ka horoia tika ngā pupuhi hau matao i te tere o te tekau mita ia hekona ki runga i ngā mata o te tokotoko whakamahana, ka puta he ru wera nui me te ahotea miihini. I te wā kotahi, ka puta he waikura me te pakaru o te karāpiti tahanga i roto i te ruma korehau. Ka hua ake tēnei i te nekehanga nui o te ātete, ka heke te ōritetanga o te pāmahana o te rohe wera (>±10°C) ā, ka puta he pakeke tinei koretake o te mahi.

Ngā Pātai Auau (FAQ)
P: He aha i pai ake ai ngā pūtu waro C/C i ngā pūtu whakarewa molybdenum i roto i te maimoatanga wera korehau i runga ake i te 1350°C?
A: Ka pakarukaru te konganuku molibdenum (Mo) i ngā pāmahana teitei, ā, he tino matotoru (10.2 karamu/cm³). He rerekē, ko te matotoru o ngā mea honohono C/C he ~1.8 karamu/cm³ anake, ā, ka piki ake tō rātou kaha i te pāmahana (e whakaatu ana i te kore e ngoki i raro i te 2000°C), ka whakakorea katoatia te mau o te pūtu me ngā pakaru pakarukaru.
P: He aha te rerekētanga i waenga i ngā tokotoko whakamahana karāhe kua pania ki te CVD SiC me te CVD TaC, ā, me pēhea taku whiriwhiri?
A: Ka taea e te paninga CVD SiC te tu atu ki ngā pāmahana tae atu ki te 1600°C me te utu tino pai, he mea tino pai mō ngā oumu tinei korehau me te whakakākā. Ko te paninga CVD TaC (tantalum carbide) he ira rewa tino teitei o te 3880°C me te ātete wera neke atu i te 2000°C, he mea hanga motuhake mō te whakakākā pāmahana tino teitei me ngā āhuarangi tino waikura.
P: He aha te pānga o te whakakapi i ngā taputapu ki ngā anga kawenga mama C/C ki te tere whakamatao o te hau i te wā e tinei ana i te hau pēhanga teitei?
