ʻO Alumina vs. Zirconia Ceramics: Pehea e koho ai i ka mea kūpono no nā ʻāpana ʻoihana Precision

Ua lilo nā keramika holomua i mea koʻikoʻi i ka hana ʻoihana hou. Mai nā lako hana semiconductor a me nā mīkini kikoʻī a hiki i nā mea hana lapaʻau a me nā ʻōnaehana kamaʻilio optical, hoʻohana nui ʻia nā ʻāpana keramika i nā noi kahi i hiki ʻole ai i nā metala maʻamau a me nā plastics ke hāʻawi i ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa kemika, ka insulation uila, a i ʻole ka hana dimensional.

ʻO ka alumina (Al₂O₃) a me ka zirconia (ZrO₂) kekahi o nā mea keramika holomua i hoʻohana nui ʻia. Hāʻawi nā mea ʻelua i nā waiwai mechanical maikaʻi loa a me ke kūpaʻa kemika, akā ʻokoʻa kā lākou ʻano hana. ʻO ke koho ʻana i ka mea hewa hiki ke alakaʻi i ka hāʻule ʻana o nā ʻāpana ma mua o ka manawa, nā kumukūʻai hana pono ʻole, a i ʻole nā ​​​​pilikia i ka wā o ka mīkini a me ka ʻākoakoa.

1. He aha ka Alumina Ceramic?

ʻO ka alumina ceramic, i ʻike ʻia ma ke ʻano kemika ʻo alumina oxide (Al₂O₃), ʻo ia kekahi o nā mea keramika ʻenehana i hoʻohana nui ʻia i ka hana ʻoihana.

He waiwai ia no kona hui pū ʻana o ka paʻakikī, ka pale uila, ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa i ka pala, a me ke kūpaʻa o ka mahana kiʻekiʻe.

Loaʻa ka Alumina i nā ʻano maʻemaʻe like ʻole, me nā ʻano maʻemaʻe 95%, 96%, 99%, a me nā ʻano maʻemaʻe kiʻekiʻe. Hoʻopili ka maʻemaʻe a me ke ʻano o nā mea i nā waiwai mechanical, uila, a me ka thermal hope loa.

ʻO kahi pono nui o ka alumina ʻo ia kona hiki ke hoʻokaʻawale uila. ʻO kēia ka mea e pono ai i nā lako kahi e pono ai nā ʻāpana e hāʻawi i ke kākoʻo mechanical me ka ʻole o ka hana ʻana i kahi pilina uila i makemake ʻole ʻia.

Hoʻomanaʻo pinepine ʻia ka alumina maʻemaʻe kiʻekiʻe no nā lako semiconductor ma muli o kona paʻakikī, kūpaʻa kemika, a me ka hiki ke kū i nā ʻano hana koi. Eia nō naʻe, pono e hōʻoia ʻia ke kūpono o kahi papa kikoʻī e kūʻē i ke kemika hana maoli a me nā koi haumia.

2. He aha ka Zirconia Ceramic?

ʻO ka Zirconia ceramic, a i ʻole zirconium dioxide (ZrO₂), kekahi mea keramika holomua koʻikoʻi ʻē aʻe.

ʻAʻole e like me ka alumina, ʻike nui ʻia ka zirconia no kona paʻakikī haki kiʻekiʻe i waena o nā keramika oxide. Pili kēia ʻano me ka hoʻoikaika ʻana o ka hoʻololi ʻana i nā haku mele zirconia i hoʻopaʻa pono ʻia.

ʻO Yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) kahi mea zirconia ʻenekinia i hoʻohana nui ʻia.

He kūpono ʻo Zirconia no nā ʻāpana kikoʻī e ʻike nei i ka hoʻouka mechanical pinepine ʻia, ka hoʻopili paheʻe, a i ʻole nā ​​​​kūlana kahi e koʻikoʻi ai ke kūʻē ʻana i ka laha ʻana o ka māwae.

ʻO nā noi maʻamau e komo pū me nā ʻāpana mīkini kikoʻī, nā ʻāpana kūpaʻa i ke komo ʻana, nā ʻāpana seramika e pili ana i ka lāʻau lapaʻau, a me nā ʻāpana kūkulu ʻoihana kūikawā.

Eia nō naʻe, ʻaʻole ʻoi aku ka maikaʻi o ka zirconia ma mua o ka alumina. Pono hoʻi e noʻonoʻo ʻia kona mau waiwai wela, ke kumukūʻai o nā mea, ka ʻōnaehana hoʻopaʻa ʻana, a me ka ʻike i kekahi mau kūlana kaiapuni.

3. Alumina vs. Zirconia: Nā ʻokoʻa hana koʻikoʻi

Hōʻuluʻulu ka papa ma lalo nei i nā ʻano ʻenekinia laulā. ʻOkoʻa nā waiwai maoli me ka papa o ka mea, ke kaʻina hana, ke ʻano hoʻāʻo, a me ka mahana hana.

3.1 Paʻakikī a me ke Kū'ē ʻana i ka ʻAʻahu

He mea nui ka paʻakikī no nā ʻāpana keramika i hōʻike ʻia i ka friction pinepine ʻia, nā ʻāpana abrasive, a i ʻole ka hoʻopili paheʻe. Hāʻawi ʻo Alumina i ka paʻakikī kiʻekiʻe a me ke kūpaʻa abrasion maikaʻi loa. Hāʻawi pū ʻo Zirconia i ke kūpaʻa ʻaʻahu maikaʻi, ʻoiai ʻo kona paʻakikī haki kiʻekiʻe hiki ke lilo i mea maikaʻi ke loaʻa ka hopena i ka ʻāpana.

3.2 Paʻakikī o ka haki a me ka hilinaʻi mīkini

ʻOi aku ka palupalu o nā keramika ma mua o nā metala. Kōkua ke ʻano hoʻoikaika hoʻololi o Zirconia i ka pale ʻana i ka laha ʻana o ka māwae, e hoʻolilo ana iā ia i mea hoihoi no nā ʻāpana i hōʻike ʻia i ke kaumaha mechanical a i ʻole ka hopena. Hāʻawi ʻo Alumina i ka ikaika maikaʻi a me ka paʻakikī, akā ʻoi aku ka haʻahaʻa o kona paʻakikī haki ma mua o ka Y-TZP zirconia.

3.3 Nā Waiwai Uila a me ka Wera

Hoʻohana nui ʻia ka Alumina no ka insulation uila ma muli o kona resistivity uila kiʻekiʻe. Loaʻa iā Zirconia nā waiwai insulating, akā ʻo kona conductivity thermal haʻahaʻa e lilo ia i mea pono i nā noi kahi e koʻikoʻi ai ka hoʻopaʻa ʻana i ka hoʻoili wela.

4. ʻO wai ka mea ʻoi aku ka maikaʻi no nā lako Semiconductor?

Hoʻohana pinepine ʻia ka Alumina i nā lako semiconductor ma muli o kona insulation uila, paʻakikī kiʻekiʻe, a me ke kūpaʻa kemika. Hiki ke noʻonoʻo ʻia ʻo Zirconia no nā noi e koi ana i ka paʻakikī haki nui a i ʻole ka hana mechanical kūikawā.

5. Pehea e pili ai nā kaʻina hana hana i ka hana o nā ʻāpana seramika

ʻO ke kaʻina hana hana keramika maʻamau e komo pū ana me kekahi mau pae:

6. Hihia ʻenekinia hoʻohālike: Ke koho ʻana i ka mea seramika no kahi ʻāpana alakaʻi kikoʻī

7. No ke aha he mea nui ka hana ʻana i ka Precision

Hiki i ka mea keramika kūpono ke hāʻule inā ʻaʻole i hoʻokō ka ʻāpana i hoʻopau ʻia i kāna mau koi dimensional a i ʻole ka ʻili.ʻO St.Cera, uhi ke kaʻina hana ʻana i ka mālama ʻana i ka pauka seramika, ke kaomi maloʻo, ke kaomi isostatic anu, ka sintering, ka wili kūloko a me ka cylindrical, ka lapping mokulele a me ka polishing, a me ka machining CNC.

Hana ka ʻoihana i nā mea hoʻoheheʻe hopena seramika, nā ʻāpana ʻāpana seramika semiconductor, nā paipu seramika, nā koʻokoʻo seramika, nā ʻāpana kūkulu, a me nā ʻāpana seramika kikoʻī i hana kūikawā ʻia.
