ʻO nā mea hana kiʻekiʻe kiʻekiʻe kiʻekiʻe: silicon carbide, alumina, zirconia, silicon nitride

Ma ka mākeke, ʻoi aku ka maʻalahi o nā mea seramika kūikawā: silicon carbide, alumina, zirconia, silicon nitride.Ke koi mākeke piha, e nānā i ka pono o kēia mau ʻano mea.
Loaʻa i ka Silicon carbide ka maikaʻi o ke kumukūʻai maʻalahi, ke kūpaʻa erosion maikaʻi, ka ikaika kiʻekiʻe, ʻo ka hemahema nui ka maʻalahi o ka oxidize, paʻakikī ke sintering.ʻO ka alumina ka mea liʻiliʻi loa, a ʻo ke kaʻina hana hoʻomākaukau o ka pauka maka mea ʻoi loa, ʻoiai ʻo ka zirconia a me ka silicon nitrous oxide i loaʻa nā hemahema i kēia ʻano, ʻo ia kekahi o nā bottlenecks e kāohi ana i ka hoʻomohala ʻana o nā mea ʻelua.ʻO Silicon nitride, ʻoi aku ka nui o ke kumukūʻai.
Ma keʻano o ka hana,ʻoiaiʻo ka ikaika, ka paʻakikī a me nā mea mechanical'ē aʻe o ka silicon nitride a me ka zirconia iʻoi aku ka maikaʻi ma mua o ka alumina, me he mea lā ua kūpono ke kumukūʻai, akā, he nui nā pilikia.ʻO ka mea mua mai ka zirconia, he kiʻekiʻe koʻikoʻi, ʻo ke kumu o ke ola ʻana o ka stabilizer, akā ʻo kona paʻakikī kiʻekiʻe ka manawa, ʻaʻole hiki ke hoʻohana ʻia i ke kiʻekiʻe o ka mahana a me ka lumi wela o ka manawa e hoʻopaʻa pono ai i ka hoʻomohala hewa ʻana o ka oxidation. ʻōlelo ʻo ia ka mea liʻiliʻi loa o nā ʻekolu ma ka mākeke.A ʻo ka silicon nitride, he mea kaulana hoʻi ia i nā makahiki he iwakālua i hala, ʻoi aku ka maikaʻi o ka ikaika haʻalulu wela a me nā hana holoʻokoʻa ʻē aʻe, akā ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana i ka mahana ma mua o nā mea ʻelua;ʻOi aku ka paʻakikī o ka hoʻomākaukau ʻana o ka nitride silicon ma mua o ka alumina, ʻoiai ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka pae nitride silicon ma mua o zirconia, akā ʻaʻole maikaʻi ka hoʻohālikelike holoʻokoʻa e like me ka alumina.
ʻO ka hana maʻalahi, paʻa paʻa, ka hoʻololi ʻana i nā huahana o nā seramika alumina i lilo i mea hoʻohana mua loa, a ua hoʻohana ʻia i nā seramika kūikawā i kēia manawa.
