Gịnị mere 7 usoro aluminum alloy siri ike oxidize?

7075 aluminum alloy, dị ka 7 usoro aluminum alloy na nnukwu zinc ọdịnaya, na-ọtụtụ ebe na-eji ụgbọelu, agha na elu-ọgwụgwụ mmepụta ụlọ ọrụ n'ihi na ya magburu onwe n'ibu Njirimara na fechaa àgwà. Agbanyeghị, enwere ụfọdụ ihe ịma aka mgbe ị na-eme ọgwụgwọ elu, ọkachasị mgbe ị na-eme anodizing iji welie nguzogide corrosion ya na isi ike elu ya.

Anodizing bụ usoro eletrọnịkị nke enwere ike imepụta ihe nkiri aluminom oxide n'elu igwe iji meziwanye nguzogide iyi ya, nguzogide corrosion na aesthetics. Otú ọ dị, n'ihi nnukwu zinc ọdịnaya na 7075 aluminum alloy na ihe mejupụtara nke Al-Zn-Mg alloy, ụfọdụ nsogbu na-adịkarị mfe ime n'oge anodizing:

1. Agba na-ekwekọghị ekwekọ:The zinc mmewere nwere mmetụta dị ukwuu na ọxịdashọn mmetụta, nke nwere ike mfe na-eduga na-acha ọcha n'ọnụ, nwa tụrụ, na-erughị eru na agba na workpiece mgbe ọxịdashọn. Nsogbu ndị a na-apụta ìhè karịsịa mgbe ị na-agbalị ime ka ọ oxidize ya na agba na-egbuke egbuke (dị ka uhie, oroma, wdg) n'ihi na nkwụsi ike nke agba ndị a adịghị mma.

2. Adhesion ezughị ezu nke ihe nkiri oxide:Mgbe a na-eji usoro ọdịnala nke sulfuric acid anodizing na-emeso 7 usoro aluminum alloys, n'ihi na nkesa na-adịghị mma na nkewa nke aluminum alloy components, nha nke micropores n'elu ihe nkiri oxide ga-adịgasị iche iche mgbe anodizing gasịrị. Nke a na-eduga n'iche dị n'ịdị mma na nchikota nke ihe nkiri oxide na ebe dị iche iche, na ihe nkiri oxide na ebe ụfọdụ nwere ike na-adịghị ike ma nwee ike ịdaba.

Iji dozie nsogbu ndị a, ọ dị mkpa ịnakwere usoro anodizing pụrụ iche ma ọ bụ melite usoro dị ugbu a, dị ka ịhazigharị ihe mejupụtara, okpomọkụ na njupụta ugbu a nke electrolyte, nke ga-emetụta àgwà na arụmọrụ nke ihe nkiri oxide. Dịka ọmụmaatụ, pH nke electrolyte ga-emetụta ọnụ ọgụgụ na-eto eto na pore Ọdịdị nke ihe nkiri oxide; njupụta nke ugbu a na-emetụta kpọmkwem na ọkpụrụkpụ na ike nke ihe nkiri oxide. Site n'ịchịkwa ihe ndị a kpọmkwem, ihe nkiri aluminom anodized nke na-egbo mkpa ụfọdụ nwere ike ịhazi ya.

Nlele na-egosi na mgbe anodizing na 7 usoro aluminum alloy, ihe oxide film na a ọkpụrụkpụ nke 30um-50um nwere ike nweta. Ihe nkiri oxide a nwere ike ọ bụghị naanị na-echebe mkpụrụ osisi aluminom nke ọma ma gbatịa ndụ ọrụ ya, kamakwa izute ihe ndị chọrọ ịrụ ọrụ kpọmkwem site n'ịgbanwe usoro usoro. N'elu nke aluminum alloy mgbe anodizing nwekwara ike-jiji ka banye organic ma ọ bụ inorganic pigmenti inye aluminum alloy ọgaranya agba izute dị iche iche aesthetic chọrọ.

Na mpempe, anodizing bụ ụzọ dị irè iji melite arụmọrụ nke 7 usoro aluminum alloys. Site n'ịgbanwe usoro usoro, a pụrụ ịkwadebe ihe nkiri nchebe nke na-ezute ihe siri ike na mkpa dị mkpa, nke na-agbasawanye ngwa ngwa nke aluminum alloys.
