Anodizing: konumohe, me ona alloys e whakamahia rite anodes, ka arahi ranei graphite e whakamahia rite cathodes. I roto i te tetahi kukū (pērā i te waikawa pungatara, waikawa oxalic, waikawa chromic, me ētahi atu) otinga conductive, i roto i ngaohiko tono me te pānga o te nāianei hiko, he tetahi matotoru i hanga (8-12um) apa i runga i te mata o te u, e he āhuatanga aunoa pai, pakeke, te waikura resistance, kakahu ātete, mātao, adsorbability me pera i runga i.
1. Degreasing: organic whakarewa degreasing, te wai e hāngai ana emulsification horoi kaihoko degreasing, degreasing iahiko.
2. Chemical orooro: I tua atu te tango i te paru i runga i te mata o te konumohe, me ona koranu ki waikawa phosphoric, me te tango i te kiriata waikura tūturu i runga i te mata o te koranu konumohe, kia whai wāhi te tïpako konumohe te ki te whakahaere i anodization muri. I te wa ano, i te oro ano hoki kua te pānga o te whakaōritenga, e taea atu maeneene te mata o te workpiece i muri i sandblasting, a he pai te kakano mata.
3. tihorenga kiriata pango: I muri i phosphorylation, he kiriata pango-hina (whakarewa pērā i parahi, nika, konupora, rino, silicon, etc, i te mea rewakore i roto i te waikawa phosphoric) tonu i runga i te mata o te workpiece, a ka tukinotia ki waikawa hauota.
4. hāpiri: Ko te tukanga o te hanga i te kiriata waikura i runga i te hua konumohe (pitoake) i raro i te mahi o te nāianei ka whakamahia i raro i te kawehiko hāngai me ngā āhuatanga motuhake o. Anodic hāora, ki te kahore i whakaritea, te tikanga tikanga Anodizing waikawa pungatara.
5. Waikano: kia Waikano kia mahi tonu i muri i te pitoake me te kore roa rawa. I muri i piti hāora, āta horoia atu te waikawa wäriu ki te wai matao (te karo i te pāmahana ara me te hiri aunoa i te membrane).
6. taati e: nui pāmahana kekeno te wai kohua nga kōputaputa, me alumina fakatahai ki rāpoi wai ki te hanga i hydrates, hanga tioata.
7. Drying: A tuu i te hua i roto i te oumu ki te pāmahana oumu whakaturia i 70 ° C. E kore e te pāmahana taatiraa e tiketike rawa, te kore he e pängia ana ki kapiti te kiriata. I mua i horoi, me horoi reira ki te wai wera ki te whakapiki ake i te pāmahana o te workpiece kia e faka'ehi'ehi mei ki te anganga meinga e te makariri rawa te workpiece.
