ʻOi aku ka ikaika o ka zirconia i hoʻopaʻa ʻia ʻo Magnesia (MSZ) i ka ʻino a me ka haʻalulu wela. Hoʻokumu ʻia nā ʻeke tetragonal liʻiliʻi i loko o nā ʻāpana cubic o nā zirconia i hoʻololi ʻia e like me ka zirconia paʻa i ka magnesium. Ke ho'āʻo ka haʻihaʻi e neʻe i loko o ka mea, hoʻololi kēia mau precipitates mai ka pae tetragonal meta-stable a i ka pae monoclinic paʻa. Hoʻonui ʻia ka precipitate ma muli o ka hoʻopiʻi ʻana i ka wahi haʻihaʻi a hoʻonui i ka paʻakikī. Ma muli o nā ʻano like ʻole o ka hoʻomākaukau ʻana o ka mea maka, hiki i ka MSZ ke ʻelepani a i ʻole ka melemele-ʻalani ke kala. ʻO MSZ, he niho ʻelepani ka waihoʻoluʻu, ʻoi aku ka maʻemaʻe a loaʻa iā ia nā ʻano mīkini ʻoi aku ka maikaʻi. Ma nā wela kiʻekiʻe (220°C a ʻoi aʻe) a me nā hoʻonohonoho wai kiʻekiʻe, ʻoi aku ka paʻa o MSZ ma mua o YTZP, a ʻo YTZP ka mea maʻamau. Ma waho aʻe, he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o MSZ a me CTE like me ka hao hao, e pale ana i ka like ʻole o ka wela ma nā ʻōnaehana ceramic-to-metal.

Ka ikaika mechanical kiʻekiʻe

He kūpono ka hoʻonui wela no nā hui ceramic-to-metal
ʻO ke kūpaʻa kemika kiʻekiʻe (nā ʻakika a me nā kumu)

Hiki ke hoʻohana ʻia ka zirconia i hoʻopaʻa ʻia ʻo Magnesia i loko o nā kīwaha, nā pamu, a me nā gaskets no ka mea ʻoi aku ka maikaʻi o ka lole a me ke kūpaʻa ʻana. ʻO ia hoʻi ka mea i makemake ʻia no ka ʻāpana petrochemical a me ka hana kemika. ʻO Zirconia ceramics kahi koho maikaʻi loa no nā ʻāpana he nui, me:
Nā seramika hale
Piʻi
ʻAʻahu ʻāpana
Hoʻohana lima lima
Pāpī i nā nozzles
Pum lima lima
Pāpī pistons
Nā mea hoʻopāpā
ʻO nā ʻāpana pahu wahie oxide paʻa
Mea hana MWD
Nā alakaʻi wili no ka hana ʻana i ka paipu
Pono hohonu, nā ʻāpana lalo
ʻO Magnesia-Stabilized Zirconia Machining
I loko o kona ʻōmaʻomaʻo, kuki, a i ʻole ka mānoanoa piha, hiki ke hana ʻia ʻo MSZ. Ke ʻano ʻōmaʻomaʻo a i ʻole ke ʻano kuki, hiki ke hana ʻia i loko o nā geometries paʻakikī. Hoʻemi ʻia ke kino zirconia ma kahi o 20% i ka wā o ke kaʻina sintering, pono ia e hoʻopaʻa pono i ka mea. Ma muli o kēia emi ʻana, ʻaʻole hiki ke hana ʻia ka zirconia pre-sintering me nā ʻae maikaʻi loa. Pono e mīkini ʻia a hoʻonani ʻia me nā mea hana daimana i mea e loaʻa ai nā ʻae paʻa loa. Ma kēia ʻenehana hana, hoʻoheheʻe ʻia ka mea ma ka hoʻohana ʻana i kahi mea hana a i ʻole huila i uhi ʻia i daimana maikaʻi loa a hiki i ka loaʻa ʻana o ke ʻano i makemake ʻia. Hiki i kēia ke hana i ka manawa a me ka pipiʻi ma muli o ke ʻano o ka paʻakikī a me ka paʻakikī.
