Pasi pemamiriro ezvinhu anoenderana neelectrolyte uye maitiro chaiwo, aruminiyamu ne alloys dzayo zvinoumba oxide film pachigadzirwa chearuminiyamu (anode) nekuda kwekushanda kwemagetsi ari kushandiswa. Chinangwa ndechekukunda zvikanganiso zvekuoma kwepamusoro uye kuramba kupfeka kwearuminiyamu alloy, kuwedzera huwandu hwekushandiswa uye kuwedzera hupenyu hwebasa.
Chii chinonzi anode?
Mubhatiri remakemikari, electrode inogona kuoxidize electrolyte inonzi anode.
Kune mhando dzakawanda dzemhinduro dzinoshandiswa muanodizing. Parizvino dzinowanzoshandiswa isulfuric acid, oxalic acid, malonic acid, sulfonic acid nezvimwewo. Chinonyanya kushandiswa pane izvi kushandisa sulfuric acid senzira yekurapa oxidative. Zvakanakira ndezvekuti firimu re dense oxide rinogona kuwanikwa, porosity yefirimu re oxide yakakurawo, filler inogona kunyoroveswa zviri nani, kune mhando dzakawanda uye magadzirirwo ezvinhu zvealuminium zvinoshanda, tekinoroji yekushanda haina kuoma, uye kushandiswa kwesimba kwakaderera.
Sei zvikamu zvearuminiyamu zvichizogadziriswa?
1. Vhara nzira yekugadzira michina.
Mushure mekugadzirwa kweCNC, panowanzova nemitsetse yezvishandiso pamusoro pezvikamu zvearuminiyamu. Kana vatengi vachida kuvandudza "chitarisiko" chezvikamu zvearuminiyamu, vazhinji vavo vanosarudza kushandisa sandblasting + anode pakugadzirisa pamusoro.
2. Kuvandudza kuramba kwengura.
Kutaura zvazviri, aruminiyamu isimbi inodzivirira ngura nekuti aruminiyamu inochinja-chinja zvakanyanya uye inonyanya kusangana nemakemikari kana okisijeni iri mumhepo kuti igadzire aruminiyamu oxide. Firimu realuminium oxide rinoonekera harionekwe nemaziso evanhu. Firimu iri realuminium oxide rakatetepa rinongoparadzanisa mhepo kuitira kuti substrate yealuminium isaoxidized. Firimu reoxide rinongoitika zvechisikigo rinoshanda seanti-oxidant.
3. Kuvandudza kuramba kwekupfekwa.
Aruminiyamu inonyanya kukwenywa nekupfekwa, uye kuomarara kwearuminiyamu hakugone kuenzaniswa nesimbi. Pamusoro peprofile yearuminiyamu yeindasitiri inozorwa anodized kwakaoma zvikuru, uye kuomarara kwefirimu reoxide kunosvika 300HV. Saka, haipfeki zvakanyanya uye haisi nyore kukwenya.
4. Kupenda pamusoro pezvigadzirwa zvearuminiyamu zvekushongedza.
Pamberi pekuiswa kweanodization nekuvhara aruminiyamu, pane maburi akawanda akakora pamusoro, ayo ari nyore kunyudza munyu wesimbi nemadhayi, uye pamusoro pezvigadzirwa zvearuminiyamu panoita mavara ane mavara.
5. Kuvandudza kuputira.
Aruminiyamu inodzora magetsi zvakanaka, asi aruminiyamu inoda kuputira dzimwe nguva. Firimu rearuminiyamu rinogadziriswa harisi kufambisa magetsi.
6. Gadzira pendi ne primer.
Mamwe mativi earuminiyamu anoda kupendwa. Pamusoro pearuminiyamu yakazorwa ane kunyungudika kwakasimba, uye chifukidziro chacho chakafanana uye chakanaka.
Ukobvu hwefirimu rose hweanodizing yenyika ndeye 10-20 microns.
Sei kuomesa mafuta kuchikosha?
Kune rumwe rutivi, nekuda kwefirimu re oxide risina kuenzana rakaumbwa zvakasikwa, ruvara rwepamusoro pealuminium alloy rwakasiyana uye haruna kunaka.
Kune rumwe rutivi, firimu re oxide rakagadzirwa nenzira yechisikigo rakatetepa, rinokuvara nyore nyore, uye harina simba mukudzivirira ngura. Firimu re oxide rekugadzira rinogadzirwa ne anodic oxidation rakafanana, rakakora uye rinodzivirira ngura yemafuta.
