Ngā Pereki Hiraka Warowaihā
Ngā Mōhiohio Hua
Pereki karawiti siliconHe rauemi ātete-waikura i hangaia ki te silicon carbide (SiC) hei rauemi mata matua. He tino pakeke, he ātete ki te kakahu, he nui te kawe wera me te ātete ki te waikura. Ko tōna wāhanga matua ko te silicon carbide, ā, ko te ihirangi kei waenganui i te 72% me te 99%. Ko ngā momo noa ko ngā pereki silicon carbide e hono ana ki te uku, ngā pereki silicon carbide e hono ana ki te silicon nitride, ngā pereki silicon carbide e hono ana ki te Sialon, me ētahi atu.
1. Ngā Āhuatanga
Te pakeketanga teitei:Ko te pakeke Mohs o ngā pereki silicon carbide he 9, ā, he tino teitei te ātete ki te kakahu.
Te kawe wera teitei:He teitei tōna kawe wera, ā, he pai mō ngā wā e hiahia ana kia tere te marara o te wera.
Ātete ki te waikura:He pai tōna pumau ki te para waikawa, ā, he pai mō ngā taiao pāmahana teitei me te waikura matū.
Ātete ki te ru wera:He pai tōna ātete ki ngā ru wera, ā, ka noho pumau ahakoa ngā huringa pāmahana tere.
2. Whakarōpūtanga
Ka taea te wehewehe i ngā pereki karawiti silicon ki ngā kāwai e whai ake nei i runga i ngā tikanga here rerekē:
Ngā pereki karawiti silicon i herea ki te uku:Ka whakamahia te uku hei here, he pai mō ngā wā e hiahia ana kia nui te kawe wera me te ātete ki ngā ru wera.
Ngā pereki silicon carbide e herea ana ki te silicon nitride:i tahuna mā te tauhohenga nitriding, me te pumau pāmahana teitei me te ātete ki te kakahu.
Ngā pereki karawiti silicon e herea ana ki te sialon:i honoa ki te paura Si3N4 me te Al2O3, he pai mō ngā taiao pāmahana teitei me te waikura matū.
