Anodizing: aluminum da kuma ta gami ana amfani da anodes, kuma kai ko graphite ake amfani da cathodes. A wani taro (kamar sulfuric acid, oxalic acid, chromic acid, da dai sauransu) conductive bayani, ta hanyar amfani da irin ƙarfin lantarki da kuma sakamako na lantarki, a wani kauri (8-12um) Layer aka kafa a farfajiya na m, wanda yana da kyau inji Properties, taurin, lalata juriya, sa juriya, rufi, adsorbability da sauransu.
1. Degreasing: Organic sauran ƙarfi degreasing, ruwa tushen emulsification tsaftacewa wakili degreasing, electrochemical degreasing.
2. Chemical polishing: Bugu da ari cire datti a farfajiya na aluminum da kuma ta gami da phosphoric acid, da kuma cire na halitta oxide fim a kan surface na aluminum gami, saboda haka cewa aluminum substrate aka fallasa zuwa sauƙaƙe m anodization. A lokaci guda, da polishing kuma yana da sakamako na leveling, wanda zai iya kara santsi surface na workpiece bayan sandblasting, da kuma surface irin zane ne mafi alhẽri.
3. peeling baki film: Bayan phosphorylation, a baki-m film (karfe kamar tagulla, nickel, manganese, da baƙin ƙarfe, silicon, da dai sauransu, wanda shi ne insoluble a phosphoric acid) ya zauna a farfajiya na workpiece, sa'an nan bi da tare da nitric acid.
4. hadawan abu da iskar shaka: The aiwatar da kafa wani oxide fim a kan wani aluminum samfurin (anode) a karkashin mataki na wani aiyuka na yanzu karkashin m electrolyte da kuma takamaiman s yanayi. Anodic hadawan abu da iskar shaka, idan ba a kayyade ba, yawanci na nufin Anodizing sulfuric acid.
5. dyeing: dyeing ya kamata a yi nan da nan bayan da anode kuma ba ma dogon. Bayan hadawan abu da iskar shaka, a hankali kurkura kashe saura acid tare da ruwan sanyi (kauce wa yawan zafin jiki Yunƙurin da membrane ne ta atomatik shãfe haske).
6. sealing: high zazzabi tafasasshen ruwa like da pores, da kuma alumina hadawa da ruwa kwayoyin samar hydrates, forming lu'ulu'u.
7. Bushewa: Place da samfurin a cikin tanda tare da tanda da zazzabi kafa a 70 ° C. A sealing zafin jiki kada ta kasance da muni, in ba haka ba fim ne yiwuwa ga fasa. Kafin wanka, shi dole ne a wanke da ruwan zafi da kara yawan zafin jiki na workpiece haka cewa guje don crack sa da workpiece zama ma sanyi.
