Ke ulu nui nei nā mea seramika i mea nui o ka hana kiʻekiʻe o ka honua. Mahalo i ko lākou paʻakikī kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, a me ka pale ʻana i ka corrosion, hoʻohana nui ʻia nā seramika holomua e like me alumina, silicon carbide, a me alumini nitride i ka aerospace, semiconductor packaging, a me nā noi biomedical. Eia nō naʻe, ma muli o ke ʻano brittleness a me ka haʻahaʻa haʻahaʻa haʻahaʻa o kēia mau mea, ua manaʻo mau ʻia kā lākou mīkini kikoʻī he paʻakikī paʻakikī. I kēia mau makahiki i hala iho nei, me ka hoʻohana ʻana i nā mea hana ʻoki hou, nā kaʻina hana composite, a me nā ʻenehana nānā naʻauao, ke lanakila mālie nei nā bottlenecks machining seramika.
Paʻakikī: Noho pū ka paʻakikī kiʻekiʻe a me ka brittleness
ʻAʻole like me nā metala, ʻoi aku ka maʻalahi o nā seramika i ka haki ʻana a me ka ʻoki ʻana i ka wā o ka mīkini. No ka laʻana, paʻakikī loa ka silicon carbide, a ua pau koke nā mea hana ʻoki kuʻuna, no laila ke ola o hoʻokahi hapaʻumi wale nō o ka mīkini metala. He pilikia nui nō hoʻi nā hopena wela. ʻO ka piʻi ʻana o ka mahana i loko o ka mīkini hiki ke alakaʻi i ka hoʻololi ʻana i ka pae a me ke koena o ke koʻikoʻi, e hopena i ka pōʻino o lalo o ka honua e hiki ke hoʻololi i ka hilinaʻi o ka huahana hope. No nā substrate semiconductor, hiki i ka pōʻino nanometer-scale ke hoʻohaʻahaʻa i ka hoʻoheheʻe ʻana o ka wela chip a me ka hana uila.
Hoʻomaka ʻenehana: Nā mea hana ʻoki Superhard a me nā kaʻina hana hui
No ka lanakila ʻana i kēia mau pilikia machining, ke hoʻolauna mau nei ka ʻoihana i nā mea hana ʻoki hou a me ka hoʻoponopono ʻana i ka hoʻoponopono ʻana. Ua hoʻololi mālie nā mea hana ʻoki carbide polycrystalline (PCD) a me cubic boron nitride (CBN) i nā mea hana ʻoki carbide kuʻuna, e hoʻomaikaʻi nui ana i ka pale ʻana a me ka paʻa o ka mīkini. Eia kekahi, ʻo ka hoʻohana ʻana i ka ʻokiʻoki ultrasonic vibration-kōkua a me ka ductile-domain machining ʻenehana ua hiki i ka "plastic-like" oki ʻana i nā mea seramika, i wehe mua ʻia e ka haki ʻana wale nō, a laila e hōʻemi ana i ka haki ʻana a me ka pōʻino lihi.
Ma ke ʻano o ka mālama ʻana i ka ʻili, ʻo nā ʻenehana hou e like me ka chemical mechanical polishing (CMP), magnetorheological polishing (MRF), a me ka plasma-assisted polishing (PAP) ke hoʻokau nei i nā ʻāpana seramika i ka wā o ka nanometer-level precision. No ka laʻana, ua loaʻa i nā substrate wela wela nitride aluminika, ma o CMP i hui pū ʻia me nā kaʻina PAP, ua loaʻa i nā pae ʻino o ka ʻili ma lalo o 2nm, he mea koʻikoʻi ia i ka ʻoihana semiconductor.
Nā Manaʻo Noi: Mai nā Chips a i ka Ola Ola
Ke unuhi wikiwiki nei kēia mau ʻenehana i nā noi ʻoihana. Ke hoʻohana nei nā mea hana Semiconductor i nā mīkini mīkini paʻa kiʻekiʻe a me nā ʻōnaehana hoʻopiʻi hewa wela e hōʻoia i ka paʻa o nā wafers seramika nui. Ma ke kahua biomedical, ua hana ʻia nā ʻāpana curved paʻakikī o nā implants zirconia me ka pololei kiʻekiʻe ma o ka poli magnetorheological. Hoʻohui ʻia me nā kaʻina laser a me ka uhi ʻana, hoʻonui hou kēia i ka biocompatibility a me ka lōʻihi.
Nā ʻano o ka wā e hiki mai ana: ʻOihana akamai a ʻōmaʻomaʻo
Ke nānā aku nei i mua, e lilo ana ka mīkini hana ceramic i mea ʻoi aku ka naʻauao a me ke aloha kaiapuni. Ma ka lima hoʻokahi, hoʻokomo ʻia nā ʻike artificial a me nā māhoe kikohoʻe i loko o nā kaʻina hana, e hiki ai i ka manawa maoli ke koho ʻana i nā ala mea hana, nā ʻano hoʻoluʻu, a me nā ʻāpana mīkini. Ma ka ʻaoʻao ʻē aʻe, ke lilo nei ka hoʻolālā ceramic gradient a me ka hoʻoheheʻe ʻana i ka ʻōpala i nā wahi wela o ka noiʻi, e hāʻawi ana i nā ala hou no ka hana ʻōmaʻomaʻo.
Ka hopena
Hiki ke ʻike mua ʻia e hoʻomau ka hoʻomohala ʻana o ka mīkini hana ceramic i ka "nano-precision, haʻahaʻa pōʻino, a me ka mana naʻauao." No ka ʻoihana hana honua, ʻaʻole kēia i hōʻike wale i kahi holomua i ka hoʻoili waiwai 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 holomua, ʻo ka holomua ʻana i ka mīkini seramika e hoʻolalelale pololei i nā ʻoihana e like me ka aerospace, semiconductors, a me ka biomedicine i kahi kiʻekiʻe.
