Ni ukubera iki 7 seriyumu ya aluminiyumu bigoye okiside?

7075 ya aluminiyumu, nk'uruhererekane 7 rwa aluminiyumu ivanze na zinc nyinshi, ikoreshwa cyane mu kirere, mu nganda no mu nganda zikora inganda zo mu rwego rwo hejuru kubera imiterere y’ubukanishi nziza n'ibiranga uburemere. Nubwo bimeze bityo ariko, hari ingorane zimwe na zimwe mugihe cyo kuvura hejuru, cyane cyane mugihe ukora anodizing kugirango yongere imbaraga zo kwangirika no gukomera kwubutaka.

Anodizing ni inzira ya electrochemicique ishobora gukorwamo firime ya aluminium oxyde hejuru yicyuma kugirango irusheho kunanirwa kwambara, kurwanya ruswa hamwe nuburanga. Ariko, kubera ibinini bya zinc biri muri 7075 ya aluminiyumu hamwe nibiranga ibiyigize bya Al-Zn-Mg, ibibazo bimwe na bimwe bikunze kugaragara mugihe cya anodizing:

1. Ibara ritaringaniye:Ikintu cya zinc kigira ingaruka zikomeye ku ngaruka ya okiside, ishobora kuganisha ku mpande zera, ibibara byirabura, n'amabara ataringaniye ku kazi nyuma ya okiside. Ibi bibazo bigaragara cyane mugihe ugerageza kubisohora mumabara meza (nkumutuku, orange, nibindi) kuko guhagarara kwaya mabara birakennye.

2. Gufata bidahagije bya firime ya oxyde:Iyo inzira gakondo ya acide sulfurike ikoreshwa mu kuvura ibice 7 bya aluminiyumu, bitewe no gukwirakwiza no gutandukanya ibice bya aluminiyumu, ubunini bwa micropore hejuru ya firime ya oxyde bizatandukana cyane nyuma yo kubisiga. Ibi biganisha ku itandukaniro mubyiza no gufatira firime ya oxyde ahantu hatandukanye, kandi firime ya oxyde ahantu hamwe na hamwe ifite intege nke kandi ishobora no kugwa.

Kugirango ukemure ibyo bibazo, birakenewe ko hajyaho uburyo bwihariye bwa anodizing cyangwa kunoza inzira ihari, nko guhindura imiterere, ubushyuhe nubucucike bwa electrolyte, bizagira ingaruka kumiterere no mumikorere ya firime ya oxyde. Kurugero, pH ya electrolyte izagira ingaruka kumikurire no mumiterere ya pore ya firime ya oxyde; ubucucike buriho bufitanye isano nubunini nubukomezi bwa firime ya oxyde. Mugucunga neza ibipimo, firime ya aluminiyumu yujuje ibyifuzo irashobora gutegurwa.

Ubushakashatsi bwerekana ko nyuma yo gukoresha anode ya serie 7 ya aluminiyumu, hashobora kuboneka firime ya oxyde ifite umubyimba wa 30um-50um. Iyi firime ya oxyde ntishobora kurinda gusa aluminium alloy substrate no kongera ubuzima bwumurimo, ariko kandi yujuje ibyangombwa bisabwa muguhindura ibipimo. Ubuso bwa aluminiyumu nyuma ya anodizing irashobora kandi gusiga irangi kugirango ikuremo ibinyabuzima kama cyangwa organic organique kugirango itange aluminium alloy amabara akungahaye kugirango yuzuze ibisabwa bitandukanye.

Muri make, anodizing nuburyo bwiza bwo kunoza imikorere ya serie 7 ya aluminium. Muguhindura ibipimo ngenderwaho, firime ikingira yujuje ubukana bwihariye nibisabwa birashobora gutegurwa, ikagura cyane umurima wa aluminiyumu.
