Ngongo Tiaki RBSiC
Ngā Mōhiohio Hua
Ngā ngongo tiaki karawiti siliconhe wāhanga ngongo motuhake i hangaia ki te rauemi uku silicon carbide (SiC), e whakamahia ana hei tiaki i ngā huānga tairongo (pēnei i ngā thermocouples) hei wāhanga matua rānei i roto i ngā taputapu kawe wai pāmahana teitei me te whakawhiti wera.
E toru ngā tukanga matua e hangaia ai ā mātou hua:Te whakapūtanga tauhohenga (RBSiC), Te whakapūtanga anō (RSiC), Te karāhe karāhe karāhe kapiti honohono ki te hākawa nitride (NSiC)
1. Ngā ngongo tiaki RBSiC
Mā te whakamahi i ngā matūriki SiC me te karāpiti hei rauemi mata, ka uru te rauemi ki te tukanga whakaurunga silicon. Ka uru te silicon wai, ka whakakī i ngā pūwero, ka tauhohe ki te karāpiti hei hanga i tētahi wāhanga SiC hou, ā, i te mutunga ka hangaia he hanganga hiato o te "anga SiC + silicon kore utu".
Ngā Āhuatanga Matua:
Te matotoru teitei me te iti o te porosity:Ka whakakīia ngā pūwero e te silicon kore utu, ka whakaiti i te pūwero ki raro iho i te 1%, ka hua ake he pai te ātete hau me te ātete ki te pēhanga teitei, he pai mō ngā pēhanga teitei me ngā pāmahana teitei.
ngā āhuatanga hiri (pērā i ngā oumu whakawera pēhanga).
Ngā āhuatanga miihini pai:He kaha piko i te pāmahana rūma 250–400MPa, he pakari pakaru teitei, ā, he pai ake te ātete ki te pānga i te karawiti silicon kua whakakātairatia anō.
Ātete pāmahana teitei:Ko te pāmahana mahi mō te wā roa ko te 1200℃. Ki runga ake i te 1350℃, ka whakangawari te silicon kore utu, ka heke te kaha, ā, ka whakawhāiti i te mahi pāmahana teitei.
He pai te tukatuka:Mā te noho mai o te silicon kore utu ka whakaiti i te pakarukaru o te rauemi, ka māmā ake te miihini ki te hanga i ngā āhua uaua, ā, ka iti ake ngā utu whakaputa.
Ngā Here:
Ka whakawhāitihia te mahi pāmahana tiketike e te silicon kore utu, ā, kāore e pai mō te mahi roa i runga ake i te 1350℃; ka tere te tauhohe o te silicon kore utu ki ngā kawakore kaha, te konumohe rewa, me ētahi atu, ka hua ake he awhe ātete waikura whaiti.
2. Ngā ngongo tiaki RSiC
Mā te whakamahi i te paura moroiti SiC tino parakore hei rauemi mata, ka whakakorikoria ki ngā pāmahana teitei (2000–2200℃). Ka hangaia he hanganga matotoru mā te whakakōhatu anō me te hanumi rohe kōpaka o ngā matūriki SiC, kāore he wāhanga hononga tāpiri.
Ngā Āhuatanga Matua:
Ātete Tino Pai ki te Pāmahana Teitei:Te pāmahana mahi roa tae atu ki te 1600℃, te ātete poto ki te 1800℃, koia te mea pai rawa atu mō te ātete pāmahana teitei i roto i ngā momo e toru, he pai mō ngā oumu pāmahana tino teitei (pērā i ngā oumu whakarewa uku me ngā oumu pupuhi whakarewa).
Ātete Pai rawa atu ki te Waikura:I ngā pāmahana tiketike, ka hangaia he kiriata tiaki matotoru SiO₂ ki te mata, hei ārai i te waikuratanga atu o te SiC o roto, e whakaatu ana i te tino pumau i roto i ngā āhuarangi waikura.
Te Tauwehenga Tino Iti o te Whakawhanuitanga Wera:Ko te tauwehenga whānui wera he 4.5 × 10⁻⁶ /℃ anake, e whakarato ana i te ātete pai ki ngā ru wera, ahakoa he iti iho i tērā o te silicon carbide e herea ana e te silicon nitride.
He pakeke teitei, he ātete ki te kakahu:He tata ki te 9 te pakeke o te Mohs, ā, he tino ātete ki te horo me te pakū o ngā rauemi, he mea e tika ana mō te rere o te hau i te pāmahana teitei me ngā āhuatanga rere wai kei roto ngā matūriki totoka.
Te pumau matū kaha:Ātete ki ngā waikawa kaha me ngā kawakore, ā, kāore e tauhohe ki te nuinga o ngā konganuku rewa.
Ngā Here:
He tino teitei te pāmahana whakawera, ka hua ake he paku teitei ake te porosity (tata ki te 5%–8%) me te paku ngoikore ake te ātete ki te pēhanga teitei; he tino teitei te pakarukaru o te pāmahana rūma, ā, kāore te ātete pānga i te rite te pai ki te silicon nitride e herea ana ki te silicon carbide.
3. Ngongo tiaki NSiC
He rauemi hiato tēnei i hangaia mā te hono pūmau i ngā matūriki SiC ki roto i te anga silicon carbide mā te whakaputa i te Si₃N₄ hei wāhanga here mā te tauhohenga nitriding.
Ngā Āhuatanga Matua:
1. Ātete Ru Wera Tino-tiketike:Nā te iti o te tauwehenga whānui wera me te pakari teitei o te wāhanga here Si₃N₄ ka taea e te ngongo tiaki te tu atu i te wera tere me te whakamatao i runga ake i te 1000℃ me te kore e pakaru nā ngā huringa pāmahana ohorere, he mea pai mō ngā āhuatanga mahi me ngā piki me ngā heke o te pāmahana.
2. Ātete Pai ki te Waikura:He tino pumau ki ngā waikawa kaha, ki ngā kawakore kaha, ki ngā konganuku rewa (pērā i te konumohe me te parahi), me ngā tote rewa, ā, he tino pai mō ngā taiao waikura i roto i ngā ahumahi matū me te whakarewa.
3. Te Kaha Mīhini Teitei:Ka eke te kaha piko o te pāmahana rūma ki te 300–500 MPa, he pai ake te pupuri i te kaha i ngā pāmahana teitei i ngā hua SiC parakore, ā, he kaha hoki te ātete ki te pānga.
4. Te pāmahana whakahaere:Te pāmahana mahi mō te wā roa 1350℃, te kaha ki te tu atu mō te wā poto tae atu ki te 1500℃.
5. Te Ārai Pai:Ka mau tonu te pai o te ārai hiko ahakoa i ngā pāmahana teitei, ka ārai i te pokanoa o te tohu thermocouple.
Ngā Here:
He iti ake te ātete ki te waikura i te silicon carbide kua whakakōatatia anō; ki te whakamahia mō te wā roa i roto i ngā hau waikura kaha, ka pakaru pea te paparanga waikura o te mata.
