7075 Aluminum Alumunum, nka serure ya 7 Aluminium hamwe nibirimo binc nyinshi, bikoreshwa cyane muri aerospace, inganda za gisirikare nisumbabyose ziterwa nubutaka bwiza bwamashini nubuzima bwiza. Ariko, hariho ibibazo bimwe na bimwe bikora ubuvuzi bwo hejuru, cyane cyane iyo bikozwe mu kayira kugirango wongere indwara yo kurwanya ruswa no gukomera.
Anoding ni inzira ya electrochemika ihita ikorwa firime yamakuru ya aluminium ishobora gushingwa hejuru yicyuma kugirango iteze imbere kurwanya, kurwanya ruswa na astethetics. Ariko, kubera ibirimo binc ndende muri 7075 Aluminium Alumunum hamwe nibiranga al-ZN-mg alloy, ibibazo bimwe bikunze kugaragara mugihe cyuzuye:
1. Ibara ritaringaniye:Ikintu cya zinc gifite ingaruka zikomeye ku ngaruka za okiside, zishobora kuganisha ku mpande zera, ibibara byirabura, n'amabara adahanitse kukazi nyuma yikigo. Ibi bibazo biragaragara cyane mugihe ugerageza kunyerera mumabara meza (nka orange, orange, nibindi) kubera ko ituze ryaya mabara ari umukene.
2. Imyitozo idahagije ya firime ya oxide:Iyo inzira gakondo ya acide ya sulfuric ikoreshwa mugufata ivurukirane 7 ya aluminium, kubera kugabana nabi no gutandukanya ibihangano bya aluminide bizatandukana cyane nyuma yo kumarana. Ibi biganisha ku gutandukanya ubwiza no gusohora film ya oxide ahantu hatandukanye, hamwe na filime ya oxide ahantu hamwe bifite intege nke kandi birashobora no kugwa.
Kugirango ukemure ibyo bibazo, birakenewe kwemeza inzira idasanzwe yo guhuza cyangwa kunoza inzira iriho, nko guhindura ibihimbano, ubushyuhe nubunini bwa electrolyte, bizahindura ubuziranenge bwa firime. Kurugero, PH ya electrolyte izagira ingaruka kumiterere yo gukura no gutunganya imiterere ya oxide; Ubucucike bwa none bufitanye isano itaziguye nubunini no gukomera kwa firime ya oxide. Mubuyobozi neza kuri ibi bipimo, firime ya anodinum ya anodinum ihuye nibikenewe runaka irashobora guhindurwa.
Ubushakashatsi bwerekana ko nyuma yo guhuza 7 seriveri ya aluminium, film ya oxide ifite ubunini bwa 30um-50um irashobora kuboneka. Iyi filime ya oxide ntishobora kurengera neza gusa amakuru ya aluminium kandi ikagura ubuzima bwa serivisi, ariko kandi yujuje ibyangombwa byihariye ahindura ibipimo. Ubuso bwa aluminium nyuma yo gufatanya nabwo bushobora no gucyarwa no gukuramo pigment kama cyangwa inorurnic gutanga aluminika amabara ahiruko kugirango ahuze nibisabwa bitandukanye.
Muri make, Ameding ni uburyo bwiza bwo kunoza imikorere yimikorere 7 seri ya aluminium alloys. Muguhindura ibipimo byabigenewe, film ikingira irahuye nubunini bwihariye nubunini bushobora gutegurwa, bikaguka cyane gushyira mubikorwa byo gusaba alloys.
