7075 txhuas alloy, raws li ib 7 koob aluminoy alloy nrog cov ntsiab lus siab zinc, tub rog thiab cov khoom lag luam siab thiab cov yam ntxwv zoo. Txawm li cas los xij, muaj qee qhov kev cov nyom thaum ua tiav kev kho deg, tshwj xeeb tshaj yog thaum ua anodizing kom txhim kho nws corrosion tsis kam thiab tawv tawv.
Anodizing yog ib qho txheej txheem electrochemical los ntawm kev ua yeeb yaj kiab txhuas tuaj yeem tsim ntawm cov hlau saum npoo los txhim kho nws cov hnav tsis kam, corrosion tsis kam thiab zoo nkauj. Txawm li cas los xij, vim muaj cov ntsiab lus zinc High hauv 7075 txhuas alloy thiab cov muaj feem sib xyaw ntawm al-zn-hg alloy, qee cov teeb meem muaj tshwm sim thaum anodizing:
1. Cov xim tsis sib xws:Lub Zinc Ntuj muaj kev cuam tshuam ntau dua rau cov nyhuv oxidation, uas tuaj yeem ua rau cov xim dawb, cov xim dub, thiab tsis xwm yeem tom qab oxidation tom qab oxidation. Cov teeb meem no tshwj xeeb tshaj yog tshwm sim thaum sim oxidize nws rau hauv cov xim ci (xws li xim ci, txiv kab ntxwv, thiab lwm yam) tsis zoo.
2. Cov lus qhia tsis txaus ntawm cov oxide zaj duab xis:Thaum cov txheej txheem tsoos ntawm sulfuric acid anodizing yog siv los kho 7 saug aluminium alllots, qhov loj ntawm cov microlo pawg ntawm cov yeeb yaj kiab oxide yuav sib txawv tom qab anodizing. Qhov no ua rau qhov sib txawv ntawm qhov zoo thiab cov yeeb yaj kiab ntawm oxide zaj duab xis ntawm cov chaw sib txawv, thiab cov yeeb yaj kiab oxide ntawm qee qhov chaw muaj zog tsis muaj zog thiab yuav poob tawm.
Txhawm rau daws cov teeb meem no, nws yog ib qho yuav tsum tau txais ib cov txheej txheem anodization tshwj xeeb, xws li siv tau qhov ntsuas hluav taws xob, uas yuav cuam tshuam cov qauv hluav taws xob, uas yuav cuam tshuam rau cov khoom siv hluav taws xob uas twb muaj lawm, uas yuav cuam tshuam qhov zoo thiab kev ua yeeb yam ntawm cov yeeb yaj kiab oxide. Piv txwv li, tus qauv hluav taws xob yuav cuam tshuam rau kev loj hlob thiab tus qauv pore cov qauv ntawm cov oxide zaj duab xis; Qhov ceev ceev tam sim no cuam tshuam txog cov tuab thiab hardness thiab hardness ntawm oxide zaj duab xis. Los ntawm kev tswj hwm cov kev txwv no, ib qho kev ua yeeb yaj kiab anodized uas tau raws li kev xav tau customized.
Kev sim qhia tau tias tom qab anodizing lub 7 series aluminium alloy, ib tug oxide zaj duab xis nrog lub tuab ntawm 30um-50um tuaj yeem tau txais. Qhov yeeb yaj kiab oxide no tsis tuaj yeem tiv thaiv cov tshuaj txhuas alloy substrate thiab txuas ntxiv nws cov kev pabcuam kev ua haujlwm, tab sis kuj ua tau raws li cov kev xav tau tshwj xeeb uas yuav tsum tau ua los ntawm kev hloov kho cov txheej txheem. Qhov saum npoo ntawm aluminium alloy tom qab anodizing kuj tseem yuav ua kom nqus cov xim organic lossis inorganic pigoy los muab cov xim txhuas allooy kom tau raws li kev ua kom zoo sib txawv.
Hauv ntej, Anodizing yog txhais tau zoo los txhim kho kev ua tau zoo ntawm 7 series aluminium alloys. Los ntawm kev kho cov txheej txheem tsis sib xws, ib zaj yeeb yaj kiab tiv thaiv uas tau raws li kev ua kom zoo thiab tuab yuav nthuav tawm daim ntawv thov cov txhuas alloys.
