Ke lilo nei nā mea seramika i mea nui o ka hana ʻana o nā mea hana kiʻekiʻe o ka honua. Mahalo i ko lākou paʻakikī kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa ʻana i ka pala, hoʻohana nui ʻia nā keramika holomua e like me ka alumina, silicon carbide, a me ka alumini nitride i ka aerospace, ka hoʻopili semiconductor, a me nā noi biomedical. Eia nō naʻe, ma muli o ka palupalu kūlohelohe a me ka paʻakikī haʻahaʻa o ka haki ʻana o kēia mau mea, ua manaʻo mau ʻia kā lākou mīkini kikoʻī he paʻakikī paʻakikī. I nā makahiki i hala iho nei, me ka hoʻohana ʻana i nā mea hana ʻoki hou, nā kaʻina hana composite, a me nā ʻenehana nānā akamai, ke lanakila mālie nei nā pilikia o ka mīkini seramika.
Paʻakikī: Paʻakikī kiʻekiʻe a me ka brittleness e noho pū ana
ʻAʻole e like me nā metala, ʻoi aku ka maʻalahi o nā keramika i ka nahā a me ka haki ʻana i ka wā o ka mīkini ʻana. No ka laʻana, he paʻakikī loa ka silicon carbide, a pinepine nā mea ʻoki kuʻuna e pau koke, e hopena ana i ka lōʻihi o ka manawa o ka mīkini ʻana i hoʻokahi hapaʻumi wale nō. He pilikia nui nō hoʻi nā hopena wela. Hiki i ka piʻi ʻana o ka mahana kūloko i ka wā o ka mīkini ʻana ke alakaʻi i nā hoʻololi pae a me nā koʻikoʻi koena, e hopena ana i ka hōʻino ʻana o lalo o ka ʻilikai e hiki ke hoʻopilikia i ka hilinaʻi o ka huahana hope loa. No nā substrates semiconductor, ʻoiai ka hōʻino nanometer-scale hiki ke hoʻohaʻahaʻa i ka hoʻolaha wela chip a me ka hana uila.
Ka Hoʻomaka ʻenehana: Nā Mea Hana ʻoki Superhard a me nā Kaʻina Hana Composite
I mea e lanakila ai i kēia mau pilikia mīkini, ke hoʻolauna mau nei ka ʻoihana i nā mea hana ʻoki hou a me nā hoʻonā hoʻomaikaʻi kaʻina hana. Ua pani mālie nā mea hana ʻoki polycrystalline diamond (PCD) a me cubic boron nitride (CBN) i nā mea hana ʻoki carbide kuʻuna, e hoʻomaikaʻi nui ana i ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa o ka mīkini. Eia kekahi, ʻo ka hoʻohana ʻana i ka ʻoki ʻana me ke kōkua o ka haʻalulu ultrasonic a me nā ʻenehana mīkini ductile-domain ua hiki ai ke ʻoki "plastic-like" o nā mea seramika, i wehe mua ʻia e ka haki brittle, a laila e hōʻemi ana i ka haki a me ka hōʻino ʻana o ka lihi.
Ma ke ʻano o ka mālama ʻana i ka ʻili, ʻo nā ʻenehana hou e like me ka polishing mechanical chemical (CMP), magnetorheological polishing (MRF), a me ka plasma-assisted polishing (PAP) e hoʻokele nei i nā ʻāpana seramika i ka wā o ka pololei nanometer-level. No ka laʻana, ʻo nā substrates alumini nitride wela, ma o CMP i hui pū ʻia me nā kaʻina hana PAP, ua hoʻokō i nā pae ʻili ma lalo o 2nm, he mea nui ia i ka ʻoihana semiconductor.
Nā Manaʻolana Noi: Mai nā ʻuala palai a i ka mālama ola kino
Ke unuhi koke ʻia nei kēia mau holomua ʻenehana i nā noi ʻoihana. Ke hoʻohana nei nā mea hana Semiconductor i nā mea hana mīkini paʻa kiʻekiʻe a me nā ʻōnaehana uku hewa wela e hōʻoia i ke kūpaʻa o nā wafers keramika nui. Ma ke kahua biomedical, ua hana ʻia nā ʻili piʻo paʻakikī o nā implants zirconia me ka pololei kiʻekiʻe ma o ka polishing magnetorheological. I hui pū ʻia me nā kaʻina hana laser a me ka uhi ʻana, hoʻonui hou kēia i ka biocompatibility a me ka lōʻihi.
Nā ʻAno Hou: Hana Hana Akamai a me ka ʻŌmaʻomaʻo
I ka nānā ʻana i mua, e lilo ka mīkini ʻana i ka keramika pololei i mea akamai a aloha i ke kaiapuni. Ma kekahi ʻaoʻao, ke hoʻokomo ʻia nei ka naʻauao hana a me nā māhoe kikohoʻe i nā kaʻina hana, e hiki ai ke hoʻonui i ka manawa maoli o nā ala hana, nā ʻano hoʻoluʻu, a me nā palena mīkini. Ma kekahi ʻaoʻao, ke lilo nei ka hoʻolālā keramika gradient a me ka hana hou ʻana i nā ʻōpala i mau wahi noiʻi, e hāʻawi ana i nā ala hou no ka hana ʻōmaʻomaʻo.
Hopena
He mea hiki ke ʻike mua ʻia e hoʻomau ka ulu ʻana o ka mīkini hana keramika i ka "nano-precision, low damage, and intelligent control." No ka ʻoihana hana honua, ʻaʻole kēia wale nō kahi holomua i ka hana ʻana i nā mea akā he hōʻailona koʻikoʻi hoʻi o ka hoʻokūkū e hiki mai ana i nā ʻoihana kiʻekiʻe. Ma ke ʻano he ʻāpana koʻikoʻi o ka hana ʻana i nā mea kiʻekiʻe, ʻo nā holomua hou i ka mīkini hana keramika e hoʻoikaika pololei i nā ʻoihana e like me ka aerospace, semiconductors, a me ka biomedicine i nā kiʻekiʻe hou.
