N'okpuru usoro electrolyte kwekọrọ na ọnọdụ usoro akọwapụtara, aluminom na alloys ya na-emepụta ihe nkiri oxide na ngwaahịa aluminom (anode) n'ihi ọrụ nke ugbu a etinyere. Ebumnuche ya bụ imeri ntụpọ nke ike elu na iyi iguzogide nke aluminom alloy, gbasaa oke ojiji ma mee ka ndụ ọrụ dịkwuo ogologo.
Gịnị bụ anode?
N'ime batrị kemịkalụ, a na-akpọ elektrọd nke nwere ike ime ka elektrọt ahụ dị oxidize anode.
E nwere ọtụtụ ụdị ngwọta eji eme anodizing. A na-ejikarị eme ihe ugbu a bụ sulfuric acid, oxalic acid, malonic acid, sulfonic acid na ndị ọzọ. Ihe kachasị na ha bụ iji sulfuric acid mee ihe dị ka ngwọta ọgwụgwọ oxidative. Uru ya bụ na enwere ike nweta ihe nkiri oxide dị oke arọ, porosity nke ihe nkiri oxide dịkwa ukwuu, enwere ike ịmịnye ihe na-ejupụta nke ọma, enwere ọtụtụ ụdị na nkọwapụta nke ihe ndị aluminom metụtara, teknụzụ ọrụ adịghị mgbagwoju anya, oriri ike dịkwa obere.
Gịnị mere e ji eme ka akụkụ aluminom bụrụ anodized?
1. Mkpuchi igwe eji ekpuchi ihe.
Mgbe a rụchara ọrụ CNC, a na-enwekarị ahịrị ngwaọrụ n'elu akụkụ aluminom. Ọ bụrụ na ndị ahịa chọrọ ime ka "ọdịdị" nke akụkụ aluminom ka mma, ọtụtụ n'ime ha na-ahọrọ iji sandblasting + anode maka ọgwụgwọ elu.
2. Meziwanye iguzogide nchara.
N'ezie, alloy aluminum bụ ígwè na-eguzogide nchara n'ihi na aluminum na-emeghachi omume nke ọma ma na-enwekarị mmeghachi omume kemịkalụ na oxygen n'ikuku iji mepụta aluminum oxide. Ihe nkiri aluminum oxide na-acha ọcha anya mmadụ na-ahụghị ya. Ihe nkiri aluminum oxide dị gịrịgịrị a na-ekewapụ ikuku ka ihe mejupụtara aluminum ghara ịcha. Ihe nkiri oxide nke na-eme n'onwe ya na-arụ ọrụ dị ka ihe na-egbochi oxidation.
3. Meziwanye iguzogide iyi.
Aluminom na-enwekarị nsogbu na nkụcha, a pụghịkwa iji ike nke alloys aluminum tụnyere ígwè. Elu nke profaịlụ aluminum ụlọ ọrụ anodized siri ike nke ukwuu, ike nke ihe nkiri oxide na-erukwa 300HV. Ya mere, ọ na-eguzogide iyi nke ukwuu ma ọ dịghị mfe ịka.
4. Agba elu nke ngwaahịa aluminom mara mma.
Tupu a na-eme ka aluminom ghara ịdị ọcha ma mechie ya, e nwere ọtụtụ oghere dị oke n'elu ya, nke dị mfe ịmịkọrọ nnu na agba ígwè, elu ngwaahịa aluminom na-etolitekwa agba agba.
5. Meziwanye mkpuchi.
Aluminom na-arụ ọrụ nke ọma n'ọkụ eletrik, mana aluminom chọrọ mkpuchi mgbe ụfọdụ. Ihe nkiri aluminom oxide nke anodized anaghị eduzi ya.
6. Mee ka agba ahụ dị mma nke ọma.
A chọrọ ka e see ụfọdụ elu aluminom. Elu nke aluminom anodized nwere mmịpụta siri ike, mkpuchi ahụ na-adịkwa otu ma mara mma karịa.
Ọkpụrụkpụ ihe nkiri izugbe nke anodizing ọkọlọtọ mba bụ 10-20 microns.
Gịnị mere anodization ji dị mkpa?
N'otu aka, n'ihi ihe nkiri oxide na-adịghị mma nke e ji aka mee, agba nke elu alloy aluminom dị iche ma ghara ịdị mma.
N'aka nke ọzọ, ihe nkiri oxide e kere eke dị gịrịgịrị, ọ na-emebi ngwa ngwa, ọ naghịkwa ekwe ka ihe ọ bụla megharịa ya. Ihe nkiri oxide e kere eke nke anodic oxidation mepụtara bụ otu, dị oke arọ ma na-eguzogide mmanụ nchara.
