Anodizing: aluminium le lits'epe tse kopantsoeng tsa lona li sebelisoa e le anodes, 'me u tsamaise kapa graphite li sebelisoa e le cathodes. Ka ea mahloriso itseng (jwalo ka acid e sulfuric, acid e oxalic, acid e chromic, joalo-joalo) tharollo conductive, ka sebelisoa gagamalo le phello ea hona joale ea motlakase, e botenya itseng (8-12um) lera Ho thehoa holim'a ba tiile ka, le nang le thepa e ntle phetha molao, thatafala, ho hanyetsa ts'enyeho, apara ho hanyetsa, kwahelang, adsorbability joalo joalo.
1. Degreasing: manyolo solvent degreasing, metsi thehiloeng emulsification ho hloekisa moemeli degreasing, motlakase ya degreasing.
2. lik'hemik'hale bentsa: Ho ekelletsa moo ho tlosa mobu holim'a aluminium le motsoako lona le asiti phosphoric, le ho tlosa tlhaho oxide e filimi ka holim 'a motsoako aluminium, e le hore le substrate aluminium e pepesa ho bebofatsa morago ga moo e anodization. Ka nako e tšoanang, ho bentsa boetse e na le phello ea batalatsa, e leng e ka ka ho eketsehileng boreleli holim 'a workpiece ka mor'a sandblasting, le botenya holim'a e molemo.
3. gommage ba batsho filimi: Ka mor'a phosphorylation, e ntšo-bohlooho filimi (tšepe tse kang koporo, nikele, a mankanese a, tšepe, silicon e, joalo-joalo, e leng insoluble ka acid e phosphoric) ntse holim'a workpiece e, 'me joale tšoaroa ka asiti nitric.
4. ho kena moea: Tsela ea eaba ba etsa e oxide e filimi ka sehlahisoa aluminium (anode) tlas'a ketso ya jwale dirisega tlasa electrolyte ngollana le maemo a itseng s. Anodic ho kena moea, haeba e se boletsweng, hangata ho bolela Anodizing acid e sulfuric.
5. daea li: daea li lokela ho etsoa hang-hang ka mor'a hore ho anode le sa nako e telele haholo. Ka mor'a ho kena moea, ka hloko rinse theoha acid e barrel ka metsi a batang (u qobe ho phahama mocheso le lera e ka tsela e iketsang ho tiisitsoe ba).
6. tiisoa: phahameng mocheso litiiso phehile metsi a pores, 'me ea alumina kopanya le limolek'hule tsa metsi ho theha hydrates, eaba ba etsa kristale.
7. omisa: Place sehlahisoa ka ontong ka mocheso ka ontong beha ka 70 ° C. Ho tiisoa ha ho mocheso lokela ho ba holimo haholo, ho seng joalo filimi ke le tsekamelo ea ho mapetsong. Pele ho hlatsoa, e lokela ho hlatsoa ka metsi a chesang ho eketsa thempereichara workpiece e le hore re qobe ho Crack bakiloeng ke workpiece ho bata haholo.
