1. He aha ke ano?
Kahiko anodichiz hoʻokumu i ka alumina anodic ma ka alumini ma o ka polarization anodic i kahi electrolyte kūpono.
ʻO ka hopena kiʻiʻoniʻoni he ʻano pale a ʻano porous paha ma muli o ke ʻano electrolyte a me ke kaʻina hana.
I nā electrolytes kokoke-kūʻole, ʻO nā kiʻiʻoniʻoni pale e maʻalahi a paʻa a kūlike; i loko o nā electrolytes acid, Hoʻopuka pinepine ʻia nā kiʻiʻoniʻoni anodic porous, me nā pores cylindrical i hoʻokaʻawale ʻia mai ka metala e kahi ʻāpana pale lahilahi.
ʻO kēia tunability hoʻolālā kekahi o nā ikaika nui o ka anodizing.
Mai kahi hiʻohiʻona ʻenehana-corrosion, ʻAʻole pinepine nā kiʻiʻoniʻoni anodic porous i ka pane hope loa iā lākou iho: Hoʻohana mau ʻia ka sila e pani a pani ʻāpana paha i nā pores a hoʻomaikaʻi i ka pale ʻana i ka corrosion ma ke kāohi ʻana i ka media corrosive mai ka hiki ʻana i ka substrate..
ʻO ia ke kumu e mālama pinepine ʻia ai ka anodizing ma ke ʻano he ʻōnaehana ma mua o kahi pae hoʻokahi, ʻoi aku i ka hana ʻenehana a me nā noi koi ʻē aʻe.
2. He aha ka Micro-Arc Oxidation?
Micro-arc oxidation/Hoʻomaopopo maikaʻi ʻia ka PEO ma ke ʻano he kaʻina hana anodic e neʻe nei ma mua o ka anodizing maʻamau i loko o ka dielectric breakdown a me ka ulu ʻana o ka plasma-kōkua..
Ma lalo o ka uila kiʻekiʻe, hana ʻia nā micro-discharges ma ke kikowaena metala-oxide-electrolyte; hehee keia mau hoolele, oxidize, a hoʻopaʻa koke i ka papa honua, ka hana ʻana i kahi uhi seramika ma kahi.
No laila ʻaʻole "anodizing mānoanoa" wale ke kaʻina hana.; he ʻano ulu ʻokoʻa ia me kāna physics hoʻokuʻu ponoʻī a me ka evolution layer.
Hoʻomaka maʻa mau ke kaʻina hana. ʻO ka pae mua e like me ka anodizing maʻamau, akā i ka manawa e hiki ai ka oxide i nā kūlana wāwahi, ʻike ʻia nā micro-arcs a hoʻomaka ka uhi ʻana ma o nā hanana plasma.
E like me ka mānoanoa o ka papa, liʻiliʻi ka hoʻokuʻu ʻana akā ʻoi aku ka ikaika, a e ulu aʻe ka uhi ʻana i kahi ʻano papa me nā ʻāpana ʻokoʻa a ʻoi aku ka palupalu.
Hōʻike kēia ulu hoʻokuʻu i ke kumu i ʻoi aku ka maʻalahi o nā uhi MAO, mānoanoa, a ʻoi aku ka like me ka seramika ma mua o nā kiʻi ʻoniʻoni anodic maʻamau.
3. ʻAno: Kiʻiʻoniʻoni Porous Oxide me ka Layer Composite Ceramic
Anodichiz: he Hoʻolālā Oxide Manaʻo
ʻO ka anodizing maʻamau e hoʻopuka i kahi papa oxide me kahi hale pale-plus-porous, ma luna o ka alumini.
Hāʻawi ka ʻāpana porous o waho i nā ala no ka hoʻopaʻa ʻana, kala ʻana, a me ka hoololi ili, ʻoiai ke hāʻawi nei ka ʻāpana pale i loko i ka pale ʻana i ka corrosion a me ka insulation uila.
Hiki ke hoʻomalu ʻia kēia hoʻolālā a ʻo ia kekahi o nā kumu nui e hoʻohana nui ʻia ai ka anodizing i ka hoʻopau ʻana i ka ʻoihana.
Mich-arc oxidation: he Layer Ceramic i hana ʻia e ka Plasma
Micro-arc oxidation, Ma ka hoʻohālikelike, puka a ʻaʻahu hoʻohuihui like-ceramic ma o ka hoʻokuʻu ʻana i ka plasma.
Loaʻa nā ʻāpana oxide mānoanoa i ka uhi, nā ala hoʻokuʻu, a me nā mea i hoʻopaʻa hou ʻia ma ka ʻāina, ʻo ka hopena i kahi hoʻolālā paʻakikī a ʻoi aku ka paʻakikī ma mua o nā kiʻiʻoniʻoni anodic maʻamau.
Ma kahi o ka hoʻoikaika ʻana i ka ʻenekinia pore no ka sila ʻana a i ʻole ke kala ʻana, Hoʻoikaika ʻo MAO i ka hoʻokumu ʻana i kahi paʻakikī, ili seramika hana.
4. ʻO ka hoʻohālikelikeʻana: Anodizing vs Micro-Arc Oxidation
Ke kū'ē neiʻo Corrosionion
Hiki i nā hana ʻelua ke hāʻawi i ka pale corrosion maikaʻi loa, akā, hana lākou pēlā ma nā ʻano like ʻole.
Ke hilinaʻi nui nei ka anodizing maikaʻi kiʻiʻoniʻoni, pore sealing, a me ka paʻa o ka hana. Ke sila pono ia, Hiki ke hana maikaʻi loa nā uhi anodic i nā kaiapuni haʻahaʻa.
Hāʻawi pū nā uhi hoʻoheheʻe micro-arc i ka pale ʻana i ka corrosion ikaika, ʻoi aku ka paʻakikī o ka uhi ʻana a mālama maikaʻi ʻia, ʻoiai hiki ke hoʻopili ʻia kā lākou hana e nā microcracks, Potiwale, a me nā hemahema i hoʻokuʻu ʻia.
Hoʻopaʻa a paʻakikī
Laulaha, hoʻomaikaʻi ka anodizing i ka lōʻihi o ka ʻili, a paʻakikī paʻakikī hoʻohana pono ʻia i kahi e pono ai ke kūpaʻa abrasion.
Akā naʻe,, Hāʻawi pinepine ʻia ka micro-arc oxidation i kahi ʻili like me ka seramika a no laila e hāʻawi i ka hana ʻoi aku ka ikaika ma lalo o ke koi ʻana i nā kūlana mechanical..
Hoʻonanea kēia i ka MAO no nā ʻāpana i ʻike ʻia i ka friction, hopena, a i ʻole ka hoʻopā pinepine ʻana.
Hana o ka Ili
ʻOi aku ka maikaʻi o ka Anodizing inā ʻo ka pahuhopu ke hoʻohui i ke kūpaʻa corrosion me ka waiwai aesthetic, hoʻopili pena, a i ʻole ka hoʻokaʻawale uila.
ʻOi aku ka nui o ka koho ʻana i ka micro-arc oxidation inā pono e hana ka ʻili ma ke ʻano he a papa ʻenekinia hana ma mua o ka hoʻopau hoʻonani.
Aia kona waiwai i ka hui pū ʻana o ka paʻakikī, kūlākuai, a me ke kū'ē i nā wahi lawelawe koʻikoʻi.
ʻO ka hoʻopili ʻana a me ke ʻano halihali.
Hoʻokumu nā ʻenehana ʻelua i nā papa oxide i hoʻohui ʻia me ka substrate ma mua o nā kiʻiʻoniʻoni i hoʻoheheʻe ʻia i waho, no laila, ʻo ka adhesion ka ikaika o kēlā me kēia.
Hiki i ka ulu ʻana i kōkua ʻia e ka plasma micro-arc oxidation ke hana i nā uhi seramika paʻa loa, ʻOiai ʻo ka pōmaikaʻi o ka anodizing ʻo ia ka hiki ke hoʻopaʻa paʻa ʻia a hoʻohui pū ʻia me ka sila a i ʻole nā pūnaewele mua.
ʻO ka hoʻokaʻawale ʻana a me ka hana o ka ʻili.
Ua hoʻohana lōʻihi ʻia ʻo Anodizing no nā noi dielectric a ma ke ʻano he kumu no nā uhi kūlohelohe.
Hiki nō hoʻi i nā uhi hoʻoheheʻe micro-arc ke hāʻawi i ka insulation uila, akā koho pinepine ʻia lākou i ka wā e neʻe ai ka mea hoʻolālā i ka lole, kūlohelohe, a i ʻole ka ʻili e like me ka seramika ma mua o ka morphology porous pololei.
ʻO ka luhi a me ka hilinaʻi o ka hale
ʻAʻole ʻokoʻa ka uhi ʻoi aku ka mānoanoa a me ka paʻakikī. No nā ʻāpana lawe ukana, 'Ōlao'ōmaʻomaʻo, ʻO ke kaumaha noho, a hiki ke hoʻopilikia i ka hana luhi.
Anodichiz, ʻoi aku ka wiwi a hoʻomalu maikaʻi ʻia, ʻoi aku ka maʻalahi i ka hoʻomanawanui dimensional a me ka hana hoʻolālā.
Hiki ke hana maikaʻi loa ka micro-arc oxidation, akā, pono ka nānā pono ʻana i ka pilina ma waena o ka pono o ka uhi a me ka hilinaʻi mechanical.
5. Ke kaʻina hana, Scalability, a me ka noonoo kaiapuni
Nā ʻano hana
ʻO ka Anodizing kahi kaʻina electrochemical makua me nā ʻano hana hoʻomalu ʻoihana paʻa.
Ua kama'āina kona puka makani hana, a ua hoʻomaʻemaʻe ʻia ka ʻenehana i nā makahiki he nui no ka hana nui.
ʻO ka micro-arc oxidation kekahi mea electrochemical i ke kumu, akā, e hana ana ia i loko o kahi aupuni ʻoi aku ka ikaika, kahi e hana nui ai nā micro-discharges i ka hoʻokumu ʻana i ka uhi. ʻO kēia ka mea i ʻoi aku ka paʻakikī o ke kaʻina hana.
Scalability
Pono nā unahi anodizing no ka hana nui, ʻoi aku ka nui ma nā ʻoihana kahi mea nui ka hoʻihoʻi ʻana a me ke ʻano.
He kūpono ia no nā ʻāpana alumini maʻamau a hoʻohui maikaʻi me ka sila, kala ʻana, a me nā hana pena.
Hiki ke scalable ka micro-arc oxidation, akā, hiki i kona paʻakikī kaʻina hana ke koi aku i ka hoʻokō ʻoihana.
Hoʻohana pinepine ʻia kahi e hōʻoia ai nā koi hana i ka paepae ʻenehana kiʻekiʻe.
Nā noʻonoʻo noʻonoʻo
Hiki ke hoʻomohala ʻia nā ʻenehana ʻelua ma nā kuhikuhi pili i ke kaiapuni, akā, ʻokoʻa lākou i ke kaumaha o ke kaʻina hana a me ka pono o ka mālama ʻana i lalo.
Ua oo ka anodizing a ua hookumu mua ka nui o na oihana hana i ka hooponopono wai a me ka hana hou.
Hiki i ka micro-arc oxidation ke hoʻemi i ka hilinaʻi ʻana i kekahi mau ʻano hana pale-pale kuʻuna, akā, pono pū ka mālama pono ʻana i nā electrolytes, ka ikehu ikehu, a me ka hana ʻana i nā huahana.
Ma na hihia elua, pili ikaika ka hana kaiapuni i ka hoʻolālā kaʻina hana a me ka hoʻomalu ʻana i nā mea kanu.
6. Kumukuai a me ka Surface-Engineering Implications
Nā noʻonoʻo noʻonoʻo
Mai ke kumu kūʻai, ʻO ka anodizing ka mea maʻamau a ʻoi aku ka maʻalahi o ke koho.
ʻO kona oʻo ʻoihana, kahua hoʻolako ākea, a me ka ʻike kaʻina hana e kōkua i ka mālama ʻana i nā koina hoʻokō.
ʻOi aku ka nui o ke kumukūʻai o ka micro-arc oxidation ma muli o kona koi ikaika, ʻoi aku ka paʻakikī o nā pono lako, a ʻoi aku ka pono o ka hoʻomalu kaʻina hana.
ʻŌlelo kēlā, ʻO ke kumu kūʻai mua ʻaʻole ia he kumu haʻahaʻa; i nā noi lawelawe koʻikoʻi, Hiki i ka micro-arc oxidation ke hāʻawi i ka maikaʻi o ke ola holoʻokoʻa.
Ili-Enekinia hopena
ʻO ka koho ma waena o ka anodizing a me ka Micro-arc oxidation ka hopena o ka hoʻoholo ʻana i ka ʻenekinia, ʻaʻole wale i ka hoʻoholo pani.
Manaʻo maikaʻi ʻia ʻo Anodizing ma ke ʻano he ʻenehana hoʻokele oxide-platform: hana ia i kahi ʻili paʻa i hiki ke hoʻopaʻa ʻia, kala ʻia, pena, a i ʻole i hana hou ʻia.
ʻOi aku ka maikaʻi o ka hoʻomaopopo ʻana i ka micro-arc oxidation ma ke ʻano he a hana ʻenehana ʻeleʻele: hana ia i mea paakiki, ʻoi aku ka paʻakikī, a ʻoi aku ka ʻili o ka noi no nā kūlana lawelawe koi.
