Kauwhata Taipitopito

Tirohanga Whānui o te Hua

I roto i ngā oumu tuku iho, he maha ngā wā ka hangaia ngā kurupae mai i ngā pereki ātete-wera, i ngā rauemi rānei kei roto i te alumina. Ahakoa he iti te utu, he ngāwari te hurihanga o aua kurupae i ngā pāmahana teitei, he tere te pirau o te kaha, ā, he poto te roa o te mahi. He rerekē, ka taea e ngā kurupae SiC te mahi tonu i te 1380°C–1650°C me te pupuri tonu i ngā āhuatanga miihini pai. E 5–10 ngā wā roa ake te roa o te mahi i ērā o ngā kurupae tuku iho, ka whakaiti nui i ngā utu tiaki, te wā kore mahi, me ngā whakapaunga whakahaere whānui.

Ngā Painga Matua o te Mahi

Ātete Pāmahana-Teitei

Ka taea te mahi mō te wā roa i runga ake i te 1380°C, me ngā rauemi SiC kua whakakikoruatia matatau e manawanui ana ki te 1650°C.
Ka pupuri i te hanganga pumau i raro i te wera nui, he mea tino pai mō ngā tono kawenga whānui i roto i ngā oumu kauhanga me ngā oumu roera.

Ngā Āhuatanga Mīhini Pai Rawa

Kaha piko noa: 250–350 MPa, he maha ngā wā he nui ake i ngā kurupae ātete tikanga.
Mā te pakeke teitei (Mohs ~9.0) ka roa te ātete ki te kakahu me te whakarerekētanga.
He tino ātete ki te ngokingoki, ā, ka ārai i te totohu, te hinga rānei i te wā e whakamahia ana mō te wā roa.

Ātete Ru Wera Tino Pai

Ka ātete ki ngā huringa whakamahana me te whakamatao tere, ā, kāore e pakaru.
Ka tu atu i ngā piki me ngā heke o te pāmahana neke atu i te 1000°C, he mea tino pai mō ngā oumu e whakamahia ana te tīmatanga me te whakamutu i ngā wā katoa.

Ātete ki te Waikura me te Waikura

Ka ātete ki ngā āhuarangi waikawa me ngā āhuarangi kawakore, tae atu ki ngā taiao waikura.
I ngā pāmahana teitei, ka hangaia e ngā mata SiC he paparanga tiaki SiO₂ matotoru, hei tiaki tōtika i te waikura atu.

Māmā & Penapena Pūngao

Kei waenga i te 2.6–3.1 karamu/cm³ te matotoru, he mama ake i te maitai, e whakaiti ana i te kawenga o te oumu.
Ka whakapai ake te kawe wera pai i te pai o te whakawhiti wera, ka whakaiti i te whakapaunga wahie, ā, ka whakarite kia ōrite te mura o te hua.

Te roa o te ora ratonga

Te roanga mahi noa: 3–5 tau, neke atu rānei, ki te whakaritea ki te 6–12 marama noa iho mō ngā kurupae ātete mura tuku iho.
Mā te whakaiti i te auau o te whakakapinga ka whakaiti i te wā kore mahi me te tiaki, ka whakapiki ake i te hua.

Ngā Āhua me ngā Whakatakotoranga o te Hua

He maha ngā whirihoranga kua hangaia mō ngā kurupae SiC kia rite ki ngā hoahoa oumu me ngā whakaritenga whakahaere rerekē:
