Oxidation yolimba pazinthu za aluminiyamu alloy ndi njira yofunika kwambiri yomwe imapangitsa kuti zinthuzo zikhale zolimba komanso zogwira ntchito. Zopangidwa ndi aluminium alloy zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chopepuka, kukana dzimbiri, komanso kuchuluka kwamphamvu kwa kulemera. Komabe, kuti apititse patsogolo katundu wawo, makutidwe ndi okosijeni olimba amagwiritsidwa ntchito kuti apange wosanjikiza woteteza pamwamba pa aluminiyumu aloyi. Nkhaniyi ifotokoza momwe makutidwe ndi okosijeni olimba pazinthu za aluminiyamu aloyi, ubwino wake, ndi ntchito zake m'mafakitale osiyanasiyana.
Hard oxidation, yomwe imadziwikanso kuti hard anodizing, ndi njira ya electrochemical yomwe imatembenuza pamwamba pa aluminiyumu alloy kukhala wosanjikiza wokhuthala, wolimba, komanso wosagwirizana ndi dzimbiri. Njirayi imaphatikizapo kumiza mankhwala a aluminiyamu alloy mu njira ya electrolyte ndikudutsa mphamvu yamagetsi. Chotsatira chake ndi kupangidwa kwa wosanjikiza wandiweyani komanso wokhazikika wa oxide pamwamba pa aluminiyamu alloy, kukulitsa kwambiri makina ake ndi mankhwala.
The hard oxidation process nthawi zambiri imakhala ndi masitepe angapo. Choyamba, chopangidwa ndi aluminium alloy chimatsukidwa bwino kuti chichotse zoipitsidwa kapena zonyansa zilizonse kuchokera pamwamba. Izi ndizofunikira kuti pakhale mawonekedwe a yunifolomu komanso apamwamba kwambiri a oxide layer. Pambuyo poyeretsa, aloyi ya aluminiyamu imamizidwa mu njira ya acidic electrolyte, monga sulfuric acid, ndipo imakhala ngati anode mumagetsi. Mphamvu yachindunji imadutsa mu electrolyte, zomwe zimapangitsa kuti makutidwe ndi okosijeni achitike pamwamba pa aluminiyumu alloy. Izi zimabweretsa mapangidwe amtundu wakuda ndi wolimba wa oxide wosanjikiza, womwe ukhoza kukhala wamtundu kuchokera ku imvi mpaka wakuda, malingana ndi ndondomeko yeniyeni ndi aloyi.
Njira ya oxidation yolimba imatha kukonzedwa kuti ikwaniritse zinthu zinazake potengera zomwe zikufunika. Ndi kusintha magawo ndondomeko monga electrolyte zikuchokera, kutentha, ndi kachulukidwe panopa, makulidwe ndi kuuma kwa oxide wosanjikiza akhoza kulamulidwa. Nthawi zambiri, makutidwe ndi okosijeni olimba amabweretsa zigawo za oxide zomwe zimakhala zokhuthala kangapo kuposa zomwe zimapangidwa muzochita zodziwika bwino za anodizing, kuyambira ma microns 25 mpaka 150. Kuchulukana kumeneku kumapereka kukana kovala bwino, kuuma, ndi chitetezo cha dzimbiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo ovuta.
Chimodzi mwazabwino zazikulu za okosijeni wolimba pazinthu za aluminiyamu alloy ndikuwongolera kwakukulu pakulimba kwapamwamba komanso kukana kuvala. Zosanjikiza zowuma komanso zolimba za oxide zomwe zimapangidwa kudzera munjira iyi zimakulitsa kwambiri kukana kwa abrasion aloyi ya aluminiyamu, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pomwe zinthuzo zimang'ambika kwambiri. Izi zimapangitsa kuti oxidation yolimba ikhale chithandizo choyenera chapamwamba pazinthu zomwe zimagwiritsidwa ntchito pamagalimoto, zakuthambo, ndi makina akumafakitale, komwe kulimba komanso moyo wautali ndizofunikira.
Kuphatikiza pa kulimba kwabwino komanso kukana kuvala, makutidwe ndi okosijeni olimba amathandizanso kukana kwa dzimbiri kwa zinthu za aluminiyamu aloyi. Kuchuluka kwa oxide wosanjikiza kumachita ngati chotchinga, kuteteza zitsulo zotayidwa pansi kuzinthu zachilengedwe monga chinyezi, mankhwala, ndi kutsitsi mchere. Izi zimapangitsa kuti zinthu zolimba zokhala ndi oxidized aluminium alloy zigwirizane bwino ndi ntchito zakunja ndi zam'madzi, pomwe kukhudzana ndi zinthu zovuta kungayambitse dzimbiri ndi kuwonongeka kwa zinthuzo.
Kuphatikiza apo, njira yolimba ya okosijeni imathanso kupititsa patsogolo mphamvu zamagetsi ndi zotenthetsera za zinthu za aluminiyamu alloy. Dense oxide layer imagwira ntchito ngati chotchinga chotchinga, ndikupangitsa kuti ikhale yoyenera pazinthu zamagetsi ndikugwiritsa ntchito komwe kuwongolera kutentha ndikofunikira. Izi zimapangitsa kuti zinthu za aluminiyamu zolimba zokhala ndi okosijeni zikhale zofunika kwambiri m'mafakitale amagetsi ndi semiconductor, pomwe zinthu zamagetsi ndi zotentha ndizofunikira kwambiri.
Zowonjezereka za pamwamba zomwe zimapezedwa kudzera mu okosijeni wolimba zimathandizanso kuti kumamatira kumawonekedwe abwino komanso ogwirizana. Izi zimapangitsa kuti zinthu zolimba zokhala ndi oxidized aluminium alloy zikhale zoyenera kugwiritsidwa ntchito pomwe zokutira, zomatira, kapena njira zomangira zimagwiritsidwa ntchito. Pamwamba pamtunda ndi kuwonjezereka kwapamwamba chifukwa cha ndondomeko yowonongeka kwa okosijeni kumapereka malo abwino olimbikitsa kumamatira mwamphamvu, kuonetsetsa kuti zokutira ndi zomatira zimamatira molimba ku gawo lapansi la aluminium alloy.
Kugwiritsa ntchito zinthu za aluminiyamu zolimba oxidized alloy ndi kosiyanasiyana komanso kufalikira m'mafakitale osiyanasiyana. M'gawo lamagalimoto, ma oxidation olimba amagwiritsidwa ntchito kuti apititse patsogolo kulimba komanso kuvala kukana kwa zinthu monga ma pistoni, masilinda, ndi magawo a injini. Makampani opanga zakuthambo amapindulanso ndi zinthu zolimba za aluminiyamu zolimba, pomwe kukana kwa dzimbiri komanso kuvala kumakhala kofunikira pazigawo za ndege ndi kapangidwe kake. Kuphatikiza apo, gawo lamakina ndi zida zamafakitale limagwiritsa ntchito zinthu zolimba za aluminium oxidized alloy pazinthu zomwe zimalemedwa ndi katundu wolemetsa, kukangana, komanso kuvala kwa abrasive.
Kuphatikiza apo, makampani apanyanja amagwiritsa ntchito kwambiri zinthu zopangira ma aluminiyamu olimba kwambiri pazida zam'madzi, zopangira, ndi zida zomwe zimakhudzidwa ndi madzi amchere komanso malo ovuta am'madzi. Mafakitale amagetsi ndi zamagetsi amagwiritsanso ntchito zinthu zolimba za aluminium oxidized alloy alloy m'mipanda yamagetsi, masinki otentha, ndi zinthu zina zomwe zimafunikira kutchingira kwamagetsi kwambiri komanso kuwongolera kutentha. Kuphatikiza apo, magawo azachipatala ndi azaumoyo amapindula ndikugwiritsa ntchito zida zolimba za aluminiyamu oxidized pazida zopangira opaleshoni, zida zamankhwala, ndi zida zomwe zimafuna kukana kuvala kwambiri komanso kuyanjana kwachilengedwe.
Pomaliza, makutidwe ndi okosijeni olimba pazinthu za aluminiyamu alloy ndi njira yovuta kwambiri yochizira pamwamba yomwe imathandizira makina, mankhwala, ndi magetsi azinthuzo. Mapangidwe a wosanjikiza wokhuthala komanso wolimba wa oxide kudzera munjira yolimba ya okosijeni amathandizira kwambiri kukana kuvala, kukana kwa dzimbiri, komanso mawonekedwe amamatira a zinthu za aluminiyamu alloy. Izi zimapangitsa kuti zinthu za aluminiyamu zolimba zokhala ndi okosijeni zikhale zofunika kwambiri m'mafakitale osiyanasiyana, kuphatikiza zamagalimoto, zakuthambo, zam'madzi, zamagetsi, komanso zaumoyo. Pamene ukadaulo ukupitilirabe patsogolo, kufunikira kwa zinthu zolimba za aluminiyamu oxidized akuyembekezeka kukula, motsogozedwa ndi kufunikira kwa zida zogwira ntchito kwambiri zomwe zimatha kupirira zovuta zogwirira ntchito.
