Ngā Raina Karāpire Hiraka Ātete-Kakahu: Te Whakakaha i te Pakari i roto i ngā Taiao Pakari

I roto i ngā ahumahi e raru ana ki ngā rauemi whakakoi, ngā pāmahana tino kino, me ngā mea waikura,ngā arai silicon carbide ātete-kakahukua tino hiahiatia mō te whakapai ake i te roa o te wā o ngā taputapu me te whai huatanga o te mahi. He mea hanga mai i te silicon carbide (RB-SiC) kua honoa ki te tauhohenga, ka whakakotahihia e ēnei arai ngā āhuatanga ā-tinana me te matū tino pai hei tino pai i roto i ngā tono tino uaua, mai i te keri ki te tukatuka matū.

Ngā Āhuatanga Rauemi Kāore i te ōrite

1. Ātete Paku Pai Rawa: He rite te pakeke o ngā raina SiC ki te taimana, ā, ka ātete rātou ki te pakū mai i ngā konganuku, te waro, me ngā paru kohuke, ā, e 5–10 ngā wā e roa ake ai te ora i te maitai me te rapa.

2. Ātete Wera: Ka pumau ki te 1,400°C, ka tu atu i ngā ru wera me ngā tukanga pāmahana teitei i roto i ngā oumu sima, i ngā oumu whakarewa rānei, me te kore e pirau.

3. Te Ātete Matū: He ātete ki ngā waikawa, ngā kawakore, me ngā whakarewa, ā, ka taea e ngā raina SiC te kawe haumaru i ngā paru waikura, i ngā matū kaha rānei.

4. Kaha Mama: Nā te ōwehenga teitei o te kaha-ki-te-taumaha ka whakaiti i te kawenga hanganga me te pupuri tonu i te pakari.

Ngā Taupānga Ahumahi Matua

I roto i te mahi keri, he mea nui ngā arai SiC mō te kawe i ngā rauemi whakakoi pērā i te rino, te waro, me ngā paru. Mā te mata maeneene ka whakaitihia te waku, ka tapahia te whakapaunga pūngao i roto i te papu paru tae atu ki te 20%. Ka tiakina hoki e rātou ngā wāhanga nui pērā i ngā awhiowhio me ngā awaawa, ka whakaitihia te wā kore mahi i puta mai i te horo.

Ka whakamahia e ngā tipu sima ngā awaawa kua whakakikoruatia ki te SiC hei whakahaere i te paraoa mata me te puehu kirikini i ngā pāmahana teitei. I roto i ngā teihana hiko waro, ka tiakina e rātou ngā pūnaha whakahaere pungarehu mai i te horo, kia mau ai te pono i roto i ngā āhuatanga wera nui.

Mō ngā paipa matū, ka mahi ngā arai SiC hei ārai kore mahi ki ngā wai waikura, hei ārai i te poke. I roto i te hanga uku me te karāhe, ka ātete rātou ki ngā rauemi puranga whakakoi me te huringa wera i roto i ngā oumu, kia mau tonu ai te pumau o ngā āhuatanga.

Ngā Painga ki ngā Rauemi Tuku Iho

Te Whai Hua o te Utu: Mā te roa o te ora o te ratonga ka whakaiti i te auau o te whakakapinga me ngā utu tiaki.

Penapena Pūngao: Ko te iti o te waku ka whakaiti i te hiahia mō te mana papu.

Haumaru Taiao: Mā te whakaiti i ngā turuturu me ngā ngaronga rauemi ka tautoko i ngā mahi pumau.

Ngāwari ki te Urutau: Ka taea te whakarite i ngā hoahoa kia uru ki ngā āhuahanga uaua, mai i ngā paipa ki ngā taputapu motuhake.

Whakamutunga

Ka tautuhi anō ngā arai waro silicon i te parenga kakahu i roto i ngā taiao ahumahi, e tuku ana i te pakari me te whai huatanga tino pai. Nā tō rātou kaha ki te tu atu i te pakū, te wera, me te waikura ka waiho hei tūāpapa mō ngā pūnaha whakahaere rauemi hou. I te mea e whakatairanga ana ngā ahumahi i te pumau me te whai huatanga utu, ka haere tonu ngā arai SiC ki te akiaki i te auahatanga, me te whakarite i te mahi pono i roto i ngā taiao tino uaua.
