Mai nā paipu halihali a i nā kaʻa ikehu hou, mai nā umu wela kiʻekiʻe a hiki i nā satelite aerospace, kahi mea i kapa ʻia ʻo "daimana ʻoihana" ke kākau mālie nei i nā palena o ka hana ʻana o kēia au.Nā keramika carbide silikona, kahi mea paʻakikī loa me ka paʻakikī ʻelua wale nō ma hope o ke daimana maoli, ke hana nei i kahi kipi leo ʻole ma nā ʻano like ʻole e like me ka ʻoihana hou, nā semiconductors, aerospace, a me ka ikehu hou ma muli o kona kūpaʻa kiʻekiʻe i ka mahana, kūpaʻa ikaika i ka radiation, a me ka conductivity thermal maikaʻi loa.
Ke hālāwai nā 'iwi paʻakikī' me ka hana pololei
Inā he porcelain polū a keʻokeʻo nā keramika kuʻuna i nā hana noʻeau a me nā hana lima, a laila ʻoi aku ka like o nā keramika silicon carbide me nā uaki Swiss i nā mea hana kikoʻī. ʻO kona paʻakikī he 3-5 mau manawa o nā keramika maʻamau, a ʻo kēia paʻakikī kokoke i nā daimana kūlohelohe e hana ai i ke kaʻina hana mīkini e like me ke kālai ʻana ma nā papa kila - pau nā mea hana ʻoki maʻamau i ka wikiwiki kupaianaha i ka wā ʻoki. ʻO ka mea paʻakikī loa, ʻo ke ʻano "paʻakikī" o ka silicon carbide e hoʻolilo iā ia i mea maʻalahi i ka haki ʻana o ka lihi me kahi hewa iki i ka wā e hana ai, ʻoi aku hoʻi no kekahi mau ʻāpana lahilahi e pono ai ke akahele like me nā hana noʻeau kristal.
Akā, ʻo ke koi o ka ʻoihana hou ke hoʻokele nei i nā holomua ʻenehana. Ua ʻike nā ʻenekinia ʻo ke kī i ka hoʻoponopono ʻana i kēia pilikia aia i ka hui pū ʻana o ka paʻakikī a me ka maʻalahi: ka mālama ʻana i nā waiwai kūloko o ka mea me ka hoʻopili ʻana i ka mana pololei i ka wā o ka hana ʻana. E like me nā kuke kiʻekiʻe e hoʻomalu nei i ka wela, hoʻomaʻamaʻa mālie nā ʻenehana hana hou i kēia mea paʻakikī ma o ka kaohi pololei ʻana i ka mahana, ke kaomi, a me ka pinepine o ka haʻalulu.
ʻEkolu mau kī e wehe ai i nā daimana ʻoihana
1. Hoʻoheheʻe ʻana i ka hoʻomehana wela
ʻO kēia kekahi o nā ʻano hana maʻamau no ka hana ʻana i nā keramika silicon carbide. Hoʻokomo kēia ʻano hana i ka pauka silicon carbide a i ʻole ka pauka i hui ʻia i loko o kahi ʻōmole kaomi wela a hana iā ia i ke ʻano ma lalo o ke ana wela a me ke kaomi. Loaʻa iā ia ka pono hana kiʻekiʻe a me ka pololei o ke kūkulu ʻana, a kūpono no ka hana ʻana i nā huahana keramika silicon carbide nui e like me nā mea ʻokiʻoki, nā papa alumini i huki wela ʻia, a pēlā aku.
2. Hoʻoheheʻe ʻana i ka grouting
He ʻano hana haʻahaʻa ke kumukūʻai a wikiwiki hoʻi kēia no nā huahana seramika silicon carbide. Hoʻohui kēia ʻano hana i ka pauka silicon carbide me nā mea hoʻohui ʻē aʻe, hoʻohui iā lākou i ka wai e hana i kahi slurry, a hoʻokomo iā ia i loko o kahi ʻōmole hoʻoheheʻe. A laila, hana ʻia a hana ʻia ma o ka hoʻomaloʻo ʻana a me ka sintering wela kiʻekiʻe, me kahi pōʻaiapuni hana pōkole a me ke kumukūʻai haʻahaʻa. He kūpono ia no ka hoʻomākaukau ʻana i nā ʻāpana ikaika kiʻekiʻe, kiʻekiʻe ka mānoanoa a me nā ʻāpana e hāpai ana i ka ukana.
3. Hana hao pauka
ʻO ka hana metallurgy pauka kahi ʻano o ke kāwili ʻana a me ke ʻano ʻana i ka pauka silicon carbide ma kahi ʻāpana, a laila sintering iā ia ma ke ana wela kiʻekiʻe a me ke kaomi kiʻekiʻe. He hana hana maʻalahi kēia ʻano hana, nā ʻano huahana like ʻole, a me ka pololei o ka hana ʻana, e kūpono ai no ka hana ʻana i nā huahana seramika kiʻekiʻe, ikaika kiʻekiʻe, a me ke kūpaʻa i ke komo ʻana.
Mai nā hāpana hoʻokolohua a hiki i ka hana nui ʻana ma ka laina hana, ʻo ka holomua i ka hana ʻana o nā keramika silicon carbide e hōʻoia i kahi ʻoiaʻiʻo: ʻaʻohe mea hiki ʻole ke hana ʻia, ʻo ka ʻenehana wale nō i haki ʻole ʻia. Me ka oʻo ʻana o nā ʻenehana hou e like me ka hana laser a me ka microwave sintering, ʻo kēia mea paʻakikī loa i hoʻoweliweli mua ʻia e hoʻoulu hou nei i nā hale hana akamai, e hoʻokomo ana i ka mana paʻakikī i loko o ka "hana akamai Kina".
I loko o ke kai ākea o ka ʻimi ʻana i ka lewa a me ka nalu ʻōmaʻomaʻo o ka ikehu maʻemaʻe, ke kākau nei nā keramika silicon carbide i kahi moʻolelo ʻoihana o kēia au me ko lākou ʻano hoʻohiwahiwa mea kū hoʻokahi. ʻO kēia hoʻokūkū ma waena o ka paʻakikī a me ka naʻauao he hiʻohiʻona mau loa ia o ke kanaka e uhaʻi ana i nā palena ʻenehana.
