I te ao tiaki hou, me te whakapai tonu i te mana o ngā patu, kei te kaha haere ngā whakaritenga mō ngā rauemi ātete matā.Karāhe silicon, he rauemi noa engari he tino kaha te āhua, kei te puta haere mai hei tino pai hou i roto i te umanga ātete matā. I tēnei rā, ka hurahia e mātou te arai ngaro o te ātete matā silicon carbide.
1、 Te hura i te mātāpono ārai-matā
Ko te kaupapa matua o te tiaki pukupuku ko te kai i te kaha o ngā pere, me te whakaroa i a rātou kia ngaro ra ano te tūponotanga. Ka whakawhirinaki ngā rauemi whakarewa tuku iho ki te whakarerekētanga kirihou hei mimiti i te kaha, ko ngā rauemi uku ia ka tutuki i tēnei whāinga mā te tukanga kuru moroiti ahurei. Hei tauira, ko ngā uku ātete-matū silicon carbide, ina pā te pere, ka pūngoi tonu te pere i runga i te mata pānga, ā, ka kuruhia te mata uku hei hanga i tētahi wāhi mārō, pakarukaru. He rite tēnei tukanga ki te hoatu i tētahi "hama" ki te pere, ā, i te tīmatanga ka mimiti i te kaha; Kātahi ka haere tonu te pere pūngoi ki mua, ka memeha te wāhi pakarukaru, ka hanga he paparanga tonu o ngā kongakonga uku; Hei whakamutunga, ka pakaru te uku i raro i te ahotea kume, ā, ka tīmata te whakarerekētanga o te pereti o muri. Ka mimiti katoatia te kaha e toe ana e te whakarerekētanga o te rauemi pereti o muri.
2, He aha te take e taea ai e te silicon carbide te ātete i ngā matā?
He matū te karawiti silicon he mea hanga nui mai i ngā hononga honohono, ā, ka taea e ōna hononga Si-C te pupuri i te kaha teitei i ngā pāmahana teitei. Nā tēnei hanganga ahurei ka whakawhiwhia ngā uku karawiti silicon ki ngā āhuatanga tino pai. He tino pakeke, tuarua ki te taimana, ki te nitride boron cubic, me te karawiti boron i roto i ngā rauemi noa. He rite ki te toa e mau ana i te pukupuku mārō, ka taea te ātete kaha ki te pānga o ngā pere; I te wa ano, he iti ake te mātotoru, ā, he mama ake te taumaha ina hangaia hei taputapu ātete matā. Ahakoa mō te whawhai takitahi, mō ngā waka me ngā waka rererangi rānei, e kore e waiho hei taumaha tāpiri, engari ka taea te whakapai ake i te nekenekehanga o ngā wae whawhai. Hei tāpiri, he pai hoki te pumau o te wera me te ātete ki te waikura matū o te karawiti silicon, ā, ka taea te mahi ātete matā i roto i ngā taiao uaua.
3, Ngā painga ahurei o te tauhohenga o te silicon carbide i roto i ngā wāhanga kua whakaritea
I roto i te tukanga whakarite o ngā uku karāhe silicon, ka tūwhera te karāhe silicon sintered tauhohenga (RBSiC), he mea tino pai mō te hanga wāhanga ritenga, mō ngā take e whai ake nei:
1. Te matotoru me te kaha nui: I raro i ngā āhuatanga pāmahana teitei, ka tauhohe te waro kore utu ki te silicon wai hei whakaputa i ngā tioata silicon carbide hou. I taua wā anō, ka uru te silicon kore utu, ka whakakī i ngā pūwero, ka whakanuia te matotoru o te rauemi, tata tata ki te matotoru ariā. Ehara i te mea ka whakawhiwhia te rauemi ki te kaha pēhi me te piko pai anake, engari ka hoatu hoki he ātete pai ki te kakahu, ka taea te tu atu i ngā āhuatanga pēhanga teitei me te pānga nui, ka tutuki i ngā whakaritenga tino pakari o ngā wāhanga kua whakaritea mō te kaha me te roa.
2. Hanganga moroiti ka taea te whakahaere: Ka taea e te tukanga whakakoi tauhohenga te whakahaere tika i te tipu o ngā kakano, ka hanga he hanganga moroiti iti, ōrite hoki. Ka whakarei ake tēnei hanganga moroiti pai i ngā āhuatanga hangarau o te rauemi, ka taea ai te noho pumau me te kore e pakaru, e kino rānei i te wā e pāngia ana e ngā taumahatanga uaua, ka whakarato i te taurangi pakari mō te pono o ngā wāhanga kua whakaritea.
3. Te tika o ngā āhuatanga: I te wā o te tukanga whakakīkī, he iti noa ngā panonitanga āhuatanga o te tauhohenga o te silicon carbide kua whakakāhia, he mea nui tēnei mō ngā wāhanga kua whakaritea. Ahakoa he mono ārai-matā kotahi a te hōia he uaua ngā āhua, he wāhanga tiaki waka motuhake rānei he tino rahi ngā whakaritenga, ka taea te hanga tika kia tino hototahi ki ngā taputapu.
4. Te pumau matū pai: Kāore he pūwero tuwhera o te silicon carbide kua whakakāhia ki te tauhohenga, ā, he uaua ki te uru te hāora me ngā matū waikura ki roto i te rauemi, nō reira he tino kaha te ātete ki te waikura me te waikura. Ko te tikanga o tēnei, ka taea tonu e ngā hua ātete-matū silicon carbide kua whakaritea te pupuri i te mahi pumau, te whakaroa i te roa o te ratonga, me te whakaiti i ngā utu tiaki i roto i ngā taiao taiao, matū rānei mō te wā roa.
4, mara tono ātete-matū Silicon carbide
Nā tōna mahi tino pai, kua whakamahia whānuitia ngā rauemi ātete-matū silicon carbide i roto i ngā mara maha:
1. Ngā taputapu takitahi: ko te arai o te koti ātete matā silicon carbide, te potae ātete matā, me ētahi atu, ka whakarato i te tiakitanga mama me te teitei ki ngā hōia, ka taea ai e rātou te whawhai ngāwari i te papa pakanga me te whai tiakitanga haumaru pono.
2. Ngā waka motuhake: pērā i ngā waka patu, ngā waka kawe moni, ngā waka ārai-whakamataku me te whakahaere tutu, me ētahi atu, he mea hanga ki te pukupuku uku silicon carbide i ngā wāhanga matua, ka taea te ātete pai i ngā whakaeke patu me te tiaki i te haumaru o ngā kaimahi me ngā rauemi nui i roto i te waka.
3. Rererangi: Ka whakamahia ngā rauemi ātete matā silicon carbide ki ngā hērakapeta me ētahi atu waka rererangi hei whakaiti i ō rātou ake taumaha, hei whakapai ake i te mahi rere, hei whakarei ake i tō rātou kaha ki te tiaki i ngā ahi a te hoariri, kia mau ai te haumaru o te rere.
I te whanaketanga tonu o te hangarau, ka haere tonu te whanaketanga me te auaha o ngā rauemi ātete-matū silicon carbide, ka hanga he rārangi parepare kaha ake mō te tiakitanga haumaru. Mena kei te hiahia koe ki ngā wāhanga ritenga o ngā uku silicon carbide kua whakatōngia, tēnā koa whakapā mai.
