He rauemi uku nui te karawiti silicon kua whakatōkia, e whakamahia whānuitia ana i roto i ngā mara pāmahana teitei, pēhanga teitei me te kaha teitei. Ko te whakatōkia tauhohenga o te SIC he taahiraa matua i roto i te whakarite rauemi SIC kua whakatōkia. Mā te whakahaere pai rawa atu o te tauhohenga SIC kua whakatōkia ka āwhina i a tātou ki te whakahaere i te āhua o te tauhohenga me te whakapai ake i te kounga o te hua. Ka matapakihia i roto i tēnei pepa te tikanga whakahaere pai rawa atu o te tauhohenga karawiti silicon kua whakatōkia.
1. Te arotautanga o ngā āhuatanga SIC sintering tauhohenga
He mea nui ngā āhuatanga tauhohenga mō te tauhohenga karawiti silicon kua whakatōngia, tae atu ki te pāmahana tauhohenga, te pēhanga tauhohenga, te ōwehenga papatipu tauhohenga me te wā tauhohenga. Ina arotauhia ngā āhuatanga tauhohenga, me whakarerekē kia rite ki ngā whakaritenga tono motuhake me te tikanga tauhohenga.
(1) Te pāmahana tauhohenga: Ko te pāmahana tauhohenga tētahi o ngā mea matua e pā ana ki te tere o te tauhohenga me te kounga o te hua. I roto i tētahi awhe, ka teitei ake te pāmahana tauhohenga, ka tere ake te tere o te tauhohenga, ka teitei ake te kounga o te hua. Heoi, ki te nui rawa te pāmahana tauhohenga ka piki ake ngā pore me ngā kapiti i roto i te hua, ka pā ki te kounga o te hua.
(2) Te pēhanga tauhohenga: He pānga anō tō te pēhanga tauhohenga ki te tere o te tauhohenga me te mātotoru o te hua. I roto i tētahi whānuitanga, ka teitei ake te pēhanga tauhohenga, ka tere ake te tere o te tauhohenga, ā, ka teitei ake te mātotoru o te hua. Heoi, ki te nui rawa te pēhanga tauhohenga ka nui ake ngā pore me ngā kapiti i roto i te hua.
(3) ōwehenga papatipu tauhohe: ko te ōwehenga papatipu tauhohe tētahi atu mea nui e pā ana ki te tere tauhohenga me te kounga o te hua. Ina tika te ōwehenga papatipu waro ki te silicon, te tere tauhohenga me te papatipu hua. Ki te kore e tika te ōwehenga papatipu tauhohenga, ka pā ki te tere tauhohenga me te papatipu hua.
(4) Te wā urupare: Ko te wā urupare tētahi o ngā āhuatanga e pā ana ki te tere o te urupare me te kounga o te hua. I roto i tētahi whānuitanga, ka roa ake te wā urupare, ka puhoi ake te tere o te urupare, ā, ka teitei ake te kounga o te hua. Heoi, ki te roa rawa te wā urupare, ka nui ake ngā pore me ngā kapiti i roto i te hua, ka pā ki te kounga o te hua.
2. Whakahaere tukanga o te carbide silicon sintering tauhohe
I roto i te tukanga o te tauhohenga SIC sintering, he mea tika kia whakahaerehia te tukanga tauhohenga. Ko te whāinga o te whakahaere he whakarite i te pumau o te tauhohenga me te ōritetanga o te kounga o te hua. Ko te whakahaere tukanga tauhohenga ko te whakahaere pāmahana, te whakahaere pēhanga, te whakahaere āhuarangi me te whakahaere kounga o te matū tauhohenga.
(1) Te whakahaere pāmahana: Ko te whakahaere pāmahana tētahi o ngā āhuatanga nui o te whakahaere tukanga tauhohenga. Te whakahaere pāmahana Me whakahaere tika te pāmahana tauhohenga kia mau tonu ai te pumau o te tukanga tauhohenga me te kounga hua ōrite. I roto i te whakaputanga hou, ko te pūnaha whakahaere rorohiko te tikanga e whakamahia ana hei whakahaere tika i te pāmahana tauhohenga.
(2) Whakahaere pēhanga: Ko te whakahaere pēhanga tētahi atu āhuatanga nui o te whakahaere tukanga tauhohenga. Mā te whakahaere i te pēhanga tauhohenga, ka taea te whakarite i te pumau o te tukanga tauhohenga me te ōritetanga o te kounga hua. I roto i te whakaputanga hou, ko te pūnaha whakahaere rorohiko te tikanga e whakamahia ana hei whakahaere tika i te pēhanga tauhohenga.
(3) Te whakahaere i te āhuarangi: Ko te whakahaere i te āhuarangi e pā ana ki te whakamahinga o tētahi āhuarangi motuhake (pērā i te āhuarangi kore mahi) i roto i te tukanga tauhohenga hei whakahaere i te tukanga tauhohenga. Mā te whakahaere i te āhuarangi, ka taea te whakarite i te pumau o te tukanga tauhohenga me te ōritetanga o te kounga o te hua. I roto i te whakaputanga hou, ka whakamahia te pūnaha whakahaere rorohiko hei whakahaere i te āhuarangi.
(4) Te whakahaere kounga o te matū tauhohe: Ko te whakahaere kounga o te matū tauhohe tētahi o ngā āhuatanga nui hei whakarite i te pumau o te tukanga tauhohenga me te ōritetanga o te kounga o te hua. Mā te whakahaere i te kounga o ngā matū tauhohenga, ka taea te whakarite i te pumau o te tukanga tauhohenga me te ōritetanga o te kounga o te hua. I roto i te whakaputanga hou, ka whakamahia te pūnaha whakahaere rorohiko hei whakahaere i te kounga o ngā matū tauhohenga.
Ko te whakahaere tino pai o te SIC sintering tauhohe he taahiraa matua ki te whakarite i ngā rauemi SIC sintered kounga teitei. Mā te arotau i ngā āhuatanga tauhohenga, te whakahaere i te tukanga tauhohenga me te aroturuki i ngā hua tauhohenga, ka taea te whakarite i te pumau o te tukanga tauhohenga me te ōritetanga o te kounga hua. I roto i te tono mahi, me whakarerekē te tauhohenga o te silicon carbide sintered kia rite ki ngā horopaki tono motuhake kia tutuki ai ngā whakaritenga tono rerekē.
