ʻO ka alumina paʻakikī Zirconia, ʻike pū ʻia ʻo ZTA kahi mea e hui pū ai i ka alumina me ka zirconia. No ka hui o na seramika i kapaia AZ composites.
ʻO nā hiʻohiʻona maikaʻi o ZTA
ʻO ka alumina paʻakikī Zirconia ke kū nei, i kona mau waiwai. Loaʻa iā ia ka hoʻohana ʻana i nā noi ʻokiʻoki a me nā ʻano lapaʻau like ʻole. ʻO ka ikaika kiʻekiʻe, ʻoʻoleʻa, elasticity, ʻO ka paʻakikī a me ka pale ʻana o nā AZ composites e kūpono loa iā lākou, no keia mau noi.

ʻO ke ʻano o ZTA
ʻO ka alumina paʻakikī Zirconia (ZTA) ʻike ʻia no kona ikaika e hoʻohālikelike ʻia me ka alumina maʻemaʻe. Loaʻa kēia ikaika mai ka hoʻololi ʻana o nā hua zirconia i ka wā e hoʻokau ʻia ai lākou i ke koʻikoʻi.
ʻO ka hoʻololi ʻana i ke koʻikoʻi
Hoʻonui ka ikaika o ZTA, ma o ke kaʻina i kapa ʻia ʻo ka hoʻololi hoʻololi ʻana i ke kaumaha. Hoʻokumu kēia kaʻina hana i nā kānana e alakaʻi ai i nā māwae i ka hale zirconium e ʻae ana i nā ʻāpana zirconium e hoʻololi i nā pae a neʻe manuahi i waena o nā ʻāpana alumina..
ʻO ka Versatility o ZTA
Hōʻike ʻo ZTA i kahi ʻano waiwai e lilo ia i mea waiwai i nā noi. I ka ʻoihana ʻike ʻia ka hoʻohana ʻana ma ke ʻano he mea no ka hoʻololi ʻana a me ka hoʻoponopono hou ʻana.
ZTA i ka ʻoihana Lapaʻau
ʻO ke kūpaʻa ʻaʻahu kiʻekiʻe o ZTA he mea kūpono ia no ka hana ʻana i nā implants hana kiʻekiʻe. ʻO kona ikaika ʻokoʻa a me ka pale ʻana i ka corrosion hiki iā ia ke kū i nā ukana me ka ʻole o ka hoʻohaʻahaʻa ʻana i kūpono no nā noi lawe ukana..
ZTA i nā mea hana ʻoki
Ma muli o kona paʻakikī, hoʻohana mau ʻia ʻo ZTA i nā mea ʻoki ʻoki me nā ʻano alumina i nā noi ʻoki metala..
ZTA i loko o nā mea ʻenekinia
ʻāpana ʻenekini, nā mea labware, Hiki ke hana ʻia nā kīʻaha ʻoihana a me nā paipu refractory me ZTA.
ʻO ZTA i ka hoʻoulu ʻana i ke one
ʻO ka alumina paʻakikī Zirconia, ʻike ʻia ʻo ZTA hiki ke hoʻohana ʻia i nā noi, e like me ka hoolele one.
ʻO kekahi o nā mea maikaʻi o ZTA ʻo ia ke kumu kūʻai. Hāʻule ia ma waena o ke kumu kūʻai o Alumina a me Zirconium e ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana i nā mea.. ʻO kona paʻakikī paʻakikī i hoʻonui ʻia e kūpono ia no nā ʻāpana i loaʻa i ka hoʻouka ʻana.. Hoʻohui ʻia ke kaʻina hana sintering i kahi microstructure e hoʻonui ai i ka hana ʻaʻahu.. ʻO kona ikaika a me ka paʻakikī i hui pū ʻia me ke kūpaʻa ʻaʻahu maikaʻi loa a me ka conductivity thermal i koho maikaʻi loa i nā kula mai ka lāʻau lapaʻau a i ka hana ʻana..
