He hana hoʻopau koʻikoʻi ka electropolishing no ka hoʻokō ʻana i nā ʻili laumania loa a maʻemaʻe hoʻi e pono ai i nā ʻoihana e like me nā lāʻau lapaʻau, biotechnology, meaʻai a me nā mea inu, a me nā mea lapaʻau. ʻOiai he huaʻōlelo pili ka "frictionless", hana ka electropolishing i kahi ʻili me ka micro-roughness haʻahaʻa loa a me ka ikehu ʻili liʻiliʻi, ʻo ia hoʻi ka "frictionless" no nā mea haumia, nā microbes, a me nā wai.
Eia kahi wehewehe kikoʻī o kāna hana a me ke kumu he kūpono ia no nā noi hygienic:
He aha ka Electropolishing?
ʻO ka electropolishing kahi hana electrochemical e wehe ana i kahi papa lahilahi a kāohi ʻia o ka mea (maʻamau 20-40µm) mai kahi ʻili metala, ʻo ka hapa nui o nā kila kila austenitic (e like me 304 a me 316L). Hana ka ʻāpana ma ke ʻano he anode (+) i loko o kahi ʻauʻau electrolytic (pinepine he hui ʻana o nā waikawa sulfuric a me phosphoric). Ke hoʻopili ʻia ke au, hoʻoheheʻe ʻia nā ion metala mai ka ʻili i loko o ka electrolyte.
ʻO ke ʻano hoʻomaʻemaʻe ʻelua-kahua
1. Hoʻohālikelike Macro (Hoʻohālikelike Anodic):
ʻOi aku ke kiʻekiʻe o ke au ma nā piko (nā kiko kiʻekiʻe microscopic) a me nā lihi ma mua o nā awāwa ma muli o ka kokoke loa i ka cathode.
· ʻO kēia ke kumu o ka heheʻe wikiwiki ʻana o nā piko ma mua o nā awāwa, e hoʻohālikelike ana i ka ʻili holoʻokoʻa a wehe i nā ʻōpala, nā burrs, a me nā māka o ka mea hana mai ka hana ʻana.
2. Hoʻomaʻemaʻe iki (ʻĀlohilohi Anodic):
Ma kahi pae microscopic, ʻo ka ʻili he hui ʻana o nā ʻano hua kristal like ʻole a me nā mea inclusion.
· Hoʻoheheʻe mua ka electropolishing i ka mea liʻiliʻi ka paʻa, amorphous, a i ʻole ka mea i hoʻokaumaha ʻia, e waiho ana i kahi ʻili i hoʻomalu ʻia e ka ʻano crystalline paʻa loa a paʻa.
· Hoʻomaʻemaʻe kēia kaʻina hana i ka ʻili ma kahi pae sub-micron, e hōʻemi nui ana i ka ʻOʻoleʻa ʻIli (Ra). Loaʻa paha i kahi ʻili i hoʻopili ʻia me ka mīkini kahi Ra o 0.5 - 1.0 µm, ʻoiai hiki i kahi ʻili i hoʻopili ʻia me ka electropolish ke hoʻokō iā Ra < 0.25 µm, pinepine i ka haʻahaʻa e like me 0.1 µm.
No ke aha e hana ai kēia i kahi ʻili "Hygienic" a i ʻole "Frictionless"
Hoʻohālikelike Pololei: Polishing Mechanical vs. Electropolishing
| Hiʻona | Ka Hoʻopili ʻana i ka Mekanika (Abrasive) | Hoʻopili uila (Electrochemical) |
| ʻIkepili ʻIli | Hoʻopili a pelu i ka metala ma luna o nā piko a me nā awāwa. Hiki ke hoʻopaʻa i nā mea haumia. | Wehe i nā mea mai nā piko, e hoʻopālahalaha ana i ka ʻili. ʻAʻohe mea haumia i hoʻokomo ʻia. |
| Ka wehe ʻana i nā ʻōpala | ʻAʻole paha e hiki i nā ʻili o loko a i ʻole nā micro-burrs. | Hoʻoponopono like i nā ʻili a pau i hōʻike ʻia, me nā geometries kūloko paʻakikī. |
| Papa ʻAi ʻino | Hiki ke hana i kahi papa passive lahilahi, hoʻopilikia ʻia, a kūlike ʻole. | Hana i kahi papa passive chromium oxide mānoanoa, like, a paʻa hoʻi. |
| Ka pilikia o ka haumia | Ka pilikia o ka hoʻokomo ʻia ʻana o nā mea abrasive (one, grit) i loko o ka ʻili. | Hoʻomaʻemaʻe kemika i ka ʻili; wehe i ka hao i hoʻokomo ʻia a me nā ʻāpana ʻē aʻe. |
| Kūlike | Pili i ka mea hoʻohana; hiki ke ʻokoʻa ma waena o nā ʻāpana paʻakikī. | Loa like a hana hou ʻia ma ka ʻili holoʻokoʻa. |

Hōʻuluʻulu manaʻo
Hoʻokumu ka electropolishing i kahi ʻili maʻemaʻe "frictionless" ʻaʻole ma ka hoʻomālielie pono ʻana ma ke ʻano maoli, akā ma o:
1. Hoʻoheheʻe ʻia nā piko a me nā hemahema microscopic ma ke ʻano electrochemical.
2. Ke hana nei i kahi ʻili like ʻole, ʻaʻohe kīnā me nā wahi heleuma liʻiliʻi no nā mea haumia.
3. Hoʻoikaika i ka papa oxide kūpaʻa i ka palaho maoli.
4. Hoʻomaʻalahi i ka hoʻokahe wai kūpono a me ka hoʻomaʻemaʻe.
