He kiʻekiʻe ke kūpaʻa o nā keramika alumina i ka ʻaʻahu ʻana, ma muli o ko lākou microstructure kūikawā a me nā waiwai kemika.
ʻO ka mea mua, ʻo ka microstructure o nā keramika alumina he ʻano polycrystalline i haku ʻia me nā ʻāpana a me nā cell, kahi e loaʻa ai ka ikaika mechanical kiʻekiʻe. ʻO ka lua, he mea paʻakikī loa nā keramika alumina, ua like kona paʻakikī me ka daimana, paʻakikī ke komo ʻia, no laila he kiʻekiʻe kona kūpaʻa abrasive. ʻO ke kolu, he paʻa loa nā waiwai kemika o nā keramika alumina, kokoke i ka pale ʻana i ka ʻino o nā waikawa āpau, nā kumu a me nā paʻakai a me nā mea kemika ʻē aʻe, a aneane ʻaʻole i hoʻopilikia ʻia e kekahi ʻano o ka pala kemika.
Ua māhele ʻia nā keramika alumina i nā ʻano maʻemaʻe like ʻole, a ʻoi aku ke kiʻekiʻe o ka nui o Al2O3 i nā keramika alumina maʻemaʻe kiʻekiʻe. Ma keʻano laulā, ʻo ke kiʻekiʻe o ka nui o ka alumini, ʻoi aku ka maikaʻi o kona kūpaʻa ʻana i ka ʻaʻahu.
Kahi mea hou aʻe,nā keramika aluminaLoaʻa iā ia ke kūpaʻa wela maikaʻi loa, hiki ke mālama i ka hana maikaʻi loa ma nā mahana kiʻekiʻe, ka mea e hana ai i nā kūlana hana pale ʻaʻahu he nui hiki ke pāʻani i kahi hana maikaʻi loa.
No laila, ʻo kēia mau ʻano o nā keramika alumina e hana maikaʻi ai lākou i nā wahi he nui kahi e pono ai ke kū'ē ʻana i ka ʻaʻahu.
