Imiterere yumubiri hamwe na hook-beam ya gari ya moshi yihuta ikorwa hifashishijwe aluminiyumu, izwiho ibyiza byayo nkubucucike buke, igipimo kinini-cy-uburemere, kurwanya ruswa neza, hamwe nubushyuhe buke bwo hasi.Mugusimbuza ibikoresho gakondo byibyuma na aluminium, uburemere bwumubiri wa gari ya moshi buragabanuka cyane, biganisha ku gukoresha ingufu nke, kugabanya ibidukikije byangiza ibidukikije, no guteza imbere ubukungu n’imibereho.
Nyamara, aluminium na aluminiyumu bifite imiti ikora cyane.Nubwo ikora firime yuzuye ya okiside iyo ihuye na ogisijeni mu bidukikije, itanga imbaraga zo kurwanya ruswa kurusha ibyuma bisanzwe, ruswa irashobora kugaragara mugihe amavuta ya aluminiyumu akoreshwa muri gari ya moshi yihuta.Amasoko y'amazi yangirika, harimo kumeneka, kwegeranya ikirere, n'amazi ava mu butaka mugihe cyo guhagarara, birashobora guhungabanya firime ya oxyde.Kwangirika muri aluminiyumu ikoreshwa mu mubiri wa gari ya moshi yihuta cyane cyane igaragara nko kwangirika kimwe, gutobora kwangirika, kwangirika kwa crevice, no kwangirika kwa stress, bigatuma iba inzira igoye iterwa n’ibidukikije ndetse n’imiterere ya alloy.
Hariho uburyo butandukanye bwo kurwanya antikorosiyo ya aluminiyumu, nko gukoresha imiti igabanya ubukana bwa aluminiyumu ivanze n’ibidukikije.Igikoresho gisanzwe cya anticorrosive ni epoxy resin primer, ikoreshwa cyane mukurwanya amazi meza, gukomera kwa substrate, hamwe no guhuza imyenda itandukanye.
Nyamara, ugereranije nuburyo bwo kwirinda ingese, uburyo bwiza ni uburyo bwo kuvura imiti.Nyuma yo kuvura passivation ya aluminium na aluminiyumu, ubunini bwibicuruzwa hamwe nubukanishi bukomeza kutagira ingaruka, kandi nta gihinduka mumiterere cyangwa ibara.Ubu buryo buroroshye kandi butanga firime ihamye kandi irwanya ruswa ugereranije na anticorrosive coatings.Filime ya passivation yakozwe binyuze muri aluminium alloy ivura passivation irahagaze neza kandi ifite imbaraga zo kurwanya ruswa kurusha imyenda ya anticorrosive, hamwe ninyungu ziyongera kubikorwa byo kwikosora.
Chromium idafite pasivisiyo yumuti, KM0425, irakwiriye gutambutsa ibikoresho bya aluminiyumu, amavuta ya aluminiyumu, nibicuruzwa bya aluminiyumu bipfa, byongera imbaraga zo kurwanya ruswa.Nibicuruzwa bishya kandi byujuje ubuziranenge muri rusange-intego ya passivation yibikoresho bya aluminium.Yakozwe na acide kama, ibikoresho bidasanzwe byubutaka, inzitizi nziza zo kwangirika kwangirika, hamwe na bike byihuta byihuta byihuta byihuta, ntabwo irimo aside, idafite uburozi, kandi nta mpumuro nziza.Ukurikije ibipimo by’ibidukikije bya RoHS, ukoresheje iki gisubizo cya passivation byemeza ko inzira ya passivation itangiza ibara ryumwimerere nubunini bwibikorwa byakazi mugihe byanonosoye cyane kurwanya ibikoresho bya aluminiyumu kumiti yumunyu.
