Ihe kpatara na agba na-enweghị isi nke ihe nkiri aluminom alloy oxide

Ihe atọ nwere ike ime ka agba ihe nkiri aluminom oxide profaịlụ abụghị otu:

(1) Mgbe profaịlụ aluminum anodized, e nwere nnukwu ọdịiche dị na workpiece mpaghara, oghere swing nso, nsọtụ na etiti ọnọdụ, ngwọta kọntaktị, update, na mgbanwe, nke na-eduga na-ezighị ezi agba film. Usoro mgbochi na-agụnye obere ihe nfe mgbe ị na-emezi profaịlụ aluminom na ikekwe ọgwụgwọ kwụ ọtọ, ọ bụ ezie na oke ngwọta dị ala nwere ike ime ka e guzobe map ma ọ bụ ntụpọ, nke na-abụghị ihe e zubere.

(2) Mgbe aluminom clad akụkụ nọ n'okpuru mbibi, site n'igbupụ, mpụta alclad bụ elu àgwà aluminum, agbachiri n'ime oyi akwa dị iche iche aluminum, abụọ aluminum iche, otú oxidation mgbe "benign vitiligo" dị ka tụrụ. Ndị ahịa anaghị aghọtacha ihe a na-emekarị, ndị na-emepụta ihe kwesịrị imekwu ihe iji kọwaa ọrụ ahụ, kọwaa ihe kpatara ya na otu, iji zere nghọtahie.

(3) Nsogbu na usoro ọrụ

Ọ bụghị ihe niile unyi e wepụrụ site na mpaghara mbụ film na workpiece si caustic ọgwụgwọ bụ ezughi oke;

The elu ka bụ isi mgbe alkali etching ebe ọ bụ na ìhè nhazi adịghị etinye ya ozugbo;

The workpiece si mmekọrịta n'oge nnyefe na mpụga ihe.

Mgbe vidiyo gosipụtara agba na-ekwekọghị ekwekọ, ekwesịrị ime ihe kwesịrị ekwesị iji dozie esemokwu ahụ site n'ọtụtụ akụkụ.

Emejọ onye na-agụ na-akpọ na-arịọ na workpiece site mgbe alkali etching conductive oxide film siri ike nweta ihe mere alkaline etching mmiri mmiri aluminum ion ìgwè dị elu, mgbe mwepu nke ọtụtụ ihe na ọ bụ ike na-etolite conductive oxide film, na-n'ime akaụntụ ma elu aluminum ions alkali etching ngwọta, ndị ọzọ kwuru alkaline corrosion ngwọta bụ oké. Ma alkali corrosion ọsọ adịghị ngwa ngwa. Mgbe ahụ, odee na-atụ aro na-agbanwe alkaline corrosion ngwọta, n'ihi na mgbe alkaline etching mmiri mmiri na-eji ogologo oge ga-aluminom ion ìgwè ngafe, aluminum ion n'elu nke workpiece siri ike elution, si otú na-emetụta aluminum elu na conductive oxide ngwọta kọntaktị. si otú ahụ na-emetụta mmepụta nke ihe nkiri oxide. Ọzọ aro bụ na ọ bụrụ na unconditional nnọchi nke alkaline etching ngwọta, na workpiece mgbe alkali etching mgbe mmiri itucha ozugbo eruba nke mmiri itucha, na mgbe ahụ ìhè na a hydrofluoric acid nwere ndọpụ nitric acid, mgbe ahụ itucha juputara mgbe eduzi ọxịdashọn ọgwụgwọ. Mgbe ndị na-agụ na ekwentị kwuru mgbe alkali etching na mmiri ọkụ na mmetụta dị ezigbo mma. Onye edemede bụ ahụmahụ, na na mmiri ọkụ mgbe mmiri ọkụ na ozugbo mikpuru n'ime mmiri ngwa ngwa na-ahapụ, iji gbochie workpiece site akọrọ n'ihi oxidation na-emetụta guzobe conductive oxide film.
