ʻO nā mea seramika, e pili ana i nā seramika ʻoihana a i ʻole nā ceramics kiʻekiʻe, hoʻohana ʻia lākou i nā ʻano ʻoihana like ʻole, kahi o ka ikaika mechanical a me ke kū'ē ʻana i nā mana o waho (e like me ka corrosion) ka mea nui e pono ai.ʻO ka pale ʻaʻahu ka papa kuhikuhi hana nui e ana i ka mea seramika.Hoʻohana maʻamau ka poʻe i ka paʻakikī e hoʻoholo i ke kūpaʻa a me ka ikaika o nā mea alumina ceramic.ʻO ia hoʻi, ʻoi aku ka kiʻekiʻe o ka paʻakikī, ʻoi aku ka maikaʻi o ka pale ʻana.No laila pehea e hoʻāʻo ai i nā ʻāpana paʻakikī o nā seramika pale ʻaʻahu?
ʻO ka paʻakikī kekahi o nā waiwai nui a ana pinepine ʻia i nā seramika alumina.Hiki ke ho'ākāka 'ia ma ke 'ano he ana o ke ko'iko'i o ka hua o kekahi keramika a mea waiwai paha.Hōʻike ka paʻakikī i ke kūʻē ʻana o kahi keramika i ka haki, deformation, densification a me ka neʻe ʻana.ʻO ka ʻōlelo maʻamau, hoʻohana nui ʻia nā ʻano Vickers a me Knoop no ka hoʻāʻo paʻakikī o nā seramika.ʻO ka ʻenehana Vickers ka mea maʻamau.Ana ia i ka paakiki o na seramika a me na mea e ae ma ke ana ana i ka nui o theindentation waiho ʻia e ka indenter.He kūpono ia no nā ʻāpana liʻiliʻi a me nā ʻāpana lahilahi.Hoʻohana ʻo ia i kahi indenter daimana a me kahi haʻahaʻa māmā e hana i kahi indentation ma luna o ka mea i hoʻāʻo ʻia.Hiki i ka waiwai oolea ke ana i ka hohonu o ka indentation i hanaia e ka indenter.
E like me nā pono like ʻole o ka mākeke no ka hana ʻana i nā seramika alumina, hoʻopuka ʻo Chemshun Ceramics iā AL2O3 92%, AL2O3 95%alumina aʻaʻa i nā mea seramika.Hoʻopili ka ʻike alumina i ka paʻakikī o ka mea seramika i kekahi ʻano, ʻo ia hoʻi, ka pale ʻana i ka lole.Hiki i nā mea kūʻai ke koho i nā seramika ʻaʻahu me nā ʻano alumina like ʻole e like me nā pono o ke kaiapuni hana.
