Anodizing Titanium
He aha ka Titanium Anodizing
ʻO ka anodizing Titanium kahi kaʻina hana i hoʻoulu ʻia ai nā titanium oxides ma luna o kahi metala kumu kumu titanium e hoʻohana ana i ka electrolysis. Hiki ke hana i kahi kaʻina like me ka alumini, akā naʻe, pono ka anodizing alumini i ka ʻāpana e pena ʻia i mea e hana ai i ke kala i makemake ʻia. Hana ʻia kēia kaʻina hana ma ke ʻano ʻoihana no ka mea hiki ke hana ʻino. ʻAʻole koi ʻia kēia kaʻina hana kala me ka titanium ma muli o kāna kiʻiʻoniʻoni oxide e hoʻohuli ʻokoʻa i ka mālamalama ma mua o ka hapa nui o nā mea metala ʻē aʻe. Hana ia e like me kahi kiʻiʻoniʻoni lahilahi e hōʻike ana i kahi lōʻihi o ka nalu o ka mālamalama ma muli o ka mānoanoa o ke kiʻiʻoniʻoni. Ma ka hoʻololi ʻana i ka volta i hoʻohana ʻia i ke kaʻina hana anodization hiki ke hoʻomalu ʻia ke kala o ka ʻili titanium. ʻAe kēia i ka titanium e anodized i nā kala like ʻole e noʻonoʻo ai kekahi.
ʻO ka anodizing ka hoʻoheheʻe ʻia ʻana o ka ʻili o nā metala ma ke ʻano electrochemical, i ka manawa o ka mea i hoʻoheheʻe ʻia ʻo ia ka anode i ke kaapuni. Hoʻohana wale ʻia ka anodizing ma ke kālepa i nā metala, e like me: aluminika, titanium, zinc, magnesium, niobium, zirconium, a me hafnium, nona nā kiʻi ʻoniʻoni e hāʻawi i ka pale mai ka palaka holomua. Hoʻokumu kēia mau metala i nā kiʻiʻoniʻoni oxide paʻa a hoʻohui maikaʻi ʻia e hoʻokaʻawale a hoʻolōʻihi paha i ka ʻino ma o ka hana ʻana ma ke ʻano he membrane pale ion.
ʻO Titanium anodizing ka oxidation o ka titanium e hoʻololi i nā waiwai o ka ʻili o nā ʻāpana i hana ʻia, me ka hoʻomaikaʻi ʻana i nā waiwai lole a me ka hoʻomaikaʻi ʻana i nā hiʻohiʻona nani.
He aha nā pōmaikaʻi o ka Titanium Anodizing
Nui nā pono o ka anodizing titanium, me:
- Hoʻemi ʻia ka pilikia o ka ʻāʻī ʻana ma o ka hoʻemi ʻana i ka friction a me ka hoʻonui ʻana i ka paʻakikī, kahi i ʻoki ʻia nā ʻāpana.
- Hoʻomaikaʻi i ka pale ʻana mai nā ʻili anodized (passivated).
- Biocompatibility, hana ʻana i nā ʻili haʻahaʻa-corrosion a ʻaʻohe-contaminant.
- ʻO ke kumu kūʻai haʻahaʻa, kala paʻa.
- ʻO ka maikaʻi hoʻonaninani kiʻekiʻe a me kahi ākea ākea o nā kala.
- Elekike passive a haʻahaʻa-corrosion ili.
- ʻIke ʻia biocompatible, no ka mea, ʻaʻohe mea pena a me nā kala i hoʻohana ʻia.
Pehea ka lōʻihi e mau ai ka Titanium Anodized
ʻO ka ʻili anodized o kahi ʻāpana titanium e paʻa mau no nā makahiki, inā ʻaʻole i hoʻopilikia ʻia e ka abrasion a i ʻole ka hoʻouka ʻana i nā kemika i hiki ke maʻalahi i ka titanium. Paʻa loa ka Titanium i ka corrosion a ʻaʻole hiki ke hoʻolohe i nā kūlana o ka corrosion galvanic.
Hoʻopili ʻia ka Titanium Anodized i ka Rust
ʻAʻole, ʻaʻole maʻalahi ka titanium anodized i ka pala. He mea liʻiliʻi loa ka hopena o ka titanium anodized, i ka wā i hoʻokumu ʻia ai kahi kiʻiʻoniʻoni oxide paʻa pono. ʻAʻole hiki ke ʻino ʻia ka Titanium ma lalo o nā kūlana kūʻokoʻa a paʻakikī loa.
Pehea e Anodize Titanium
No ka hoʻokō ʻana i kahi pae kumu o ka anodizing o nā ʻāpana titanium liʻiliʻi, pono ʻoe e kūkulu i kahi kelepona electrochemical me kahi kumu mana DC a me kahi electrolyte kūpono. Me ke kaapuni i hoʻohui ʻia i ka ʻauʻau ka cathode a ʻo ka ʻāpana titanium ka anode, ʻo ka mea i lawe ʻia i loko o ke kelepona e oxidize i ka ʻili o ka mea. ʻO ka manawa i loko o ka ʻauʻau kaapuni, ka uila i hoʻohana ʻia, a me ka ʻike o (a me ke kemika o) ka electrolyte e hoʻololi i ka waihoʻoluʻu. He paʻakikī ke hoʻokō a mālama i ka mana pololei, akā hiki ke hōʻike maʻalahi i nā hopena ʻoluʻolu.
