Mai nā paipu hoʻokele a hiki i nā kaʻa ikehu hou, mai nā kiln wela kiʻekiʻe a hiki i nā satelite aerospace, kahi mea i kapa ʻia ʻo "industrial diamond" ke kākau hou nei i nā palena o ka hana hou.ʻO nā seramika silikoni, He mea paakiki loa me ka paakiki lua wale no i ke daimana maoli, ke kumu ia i ka hoololi malie ma na kahua like ole e like me ka oihana hou, semiconductor, aerospace, a me ka ikehu hou ma muli o kona kiʻekiʻe wela kū'ē, ikaika radiation kū'ē, a maikai loa thermal conductivity.
Ke hālāwai 'o nā iwi pa'akikī' i ka hana pololei
Inā he porcelain uliuli a keʻokeʻo nā mea hana kuʻuna ma nā ʻoihana a me nā mea hana, a laila ʻoi aku ka like o ka silicon carbide ceramics i nā wati Swiss i nā mea kani. ʻO kona paʻakikī he 3-5 mau manawa ma mua o nā seramika maʻamau, a ʻo kēia paʻakikī kokoke i nā daimana maoli e hana ai i ke kaʻina hana e like me ke kālai ʻana ma nā papa kila - pau nā mea hana ʻoki maʻamau i ka wikiwiki kupaianaha i ka wā e ʻoki ai. ʻO ka mea ʻoi aku ka paʻakikī, ʻo ke ʻano "paʻakikī" o ka silicon carbide e maʻalahi i ka haki ʻana me ka hewa liʻiliʻi i ka wā e hana ai, ʻoi aku hoʻi no kekahi mau ʻāpana ʻāpana ʻeleʻele e pono ai ke akahele like me nā hana kiʻi aniani.
Akā ʻo ka koi o ka ʻoihana hou e hoʻokau i nā holomua ʻenehana. Ua ʻike nā mea ʻenekinia ʻo ke kī i ka hoʻoponopono ʻana i kēia pilikia aia i ka hui pū ʻana o ka rigidity a me ka maʻalahi: mālama i nā waiwai intrinsic o ka mea me ka hoʻohana ʻana i ka mana pololei i ka wā o ka hana. E like me nā mea kuke kiʻekiʻe e hoʻomaʻamaʻa ana i ka wela, hoʻomaʻamaʻa mālie nā ʻenehana hana hou i kēia mea paʻakikī ma o ka hoʻomalu pono ʻana i ka wela, ke kaomi, a me ke alapine vibration.
ʻEkolu kī e wehe i nā daimana ʻoihana
1. Hoolei wela
ʻO kēia kekahi o nā ala maʻamau no ka hoʻoili ʻana i nā seramika silika carbide. Hoʻokomo kēia ʻano hana i ka pauka silicon carbide a i ʻole ka pauka i hui ʻia i loko o kahi pahu kaomi wela a hana i ke ʻano ma lalo o ka wela kiʻekiʻe a me ke kaomi. Loaʻa iā ia ka maikaʻi hana kiʻekiʻe a me ka hoʻokumu ʻana i ka pololei, a kūpono ia no ka hana ʻana i nā huahana ceramic silicon carbide nui e like me nā mea ʻoki ʻoki, nā papa alumini wela, etc.
2. Grouting molding
ʻO kēia ke kumu kūʻai haʻahaʻa a wikiwiki hoʻi no nā huahana ceramic silicon carbide. Hoʻohui kēia ʻano hana i ka pauka silika carbide me nā mea hoʻohui ʻē aʻe, hoʻohui iā lākou i ka wai e hana ai i ka slurry, a hoʻokomo ʻia i loko o ka mold. A laila, hana ʻia a hana ʻia ma o ka hoʻomaloʻo ʻana a me ka sintering kiʻekiʻe, me kahi pōʻai pōkole pōkole a me ke kumu kūʻai haʻahaʻa. He kūpono ia no ka hoʻomākaukau ʻana i nā ʻāpana ikaika kiʻekiʻe, kiʻekiʻe kiʻekiʻe a me nā mea lawe ukana.
3. Ka pauda metallurgy
ʻO ka pauka metallurgy kahi ʻano o ka hui ʻana a me ka hoʻohua ʻana i ka pauka silicon carbide i kekahi ʻāpana, a laila sintering iā ia i ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe. He kaʻina hana maʻalahi kēia ʻano hana, nā ʻano huahana like ʻole, a me ka pololei o ka hana kiʻekiʻe, kūpono ia no ka hana ʻana i nā huahana keramika kiʻekiʻe, ikaika kiʻekiʻe, a me nā lole.
Mai nā laʻana hoʻokolohua a hiki i ka hana nui ʻana ma ka laina hana, ʻo ka holomua i ka hana ʻana i ka silicon carbide ceramics e hōʻoia i ka ʻoiaʻiʻo: ʻaʻohe mea hiki ʻole ke hana ʻia, ʻo ka ʻenehana wale nō ʻaʻole i haki ʻia. Me ka ulu ʻana o nā ʻenehana hou e like me ka hoʻoili ʻana i ka laser a me ka sintering microwave, ke hoʻoulu hou nei kēia mea superhard hoʻoweliweli i nā hale hana akamai, e hoʻokomo ana i ka mana koʻikoʻi i loko o ka "hana akamai Kina".
I loko o ka moana nui o ka ʻimi ākea a me ka nalu ʻōmaʻomaʻo o ka ikehu maʻemaʻe, ke kākau nei nā seramika silicon carbide i kahi moʻolelo ʻenehana o kēia au me kā lākou mea nani. ʻO kēia hōʻike ʻana ma waena o ka paʻakikī a me ka naʻauao he hōʻailona mau loa ia o ke kanaka e haki ana i nā palena ʻenehana.
