Taw qhia ntawm anodized aluminium ntawv
Anodized Aluminium daim ntawv yog muab tso rau hauv cov qauv electrolyte (xws li sulfuric acid, chromic acid, oxalic acid, lwm.) raws li anode, nyob rau hauv cov kev mob tshwj xeeb thiab cov nyhuv ntawm sab nraud tam sim no, electrolysis. Lub anodized aluminium phaj tsim ib txheej nyias ntawm alumina ntawm nws qhov chaw, nrog lub thickness ntawm 5-20 μM. lub zog anodized zaj duab xis tuaj yeem ncav cuag 60-200 μM. Tom qab anodizing, Lub hardness thiab hnav tsis kam ntawm cov phaj txhuas tau txhim kho, uas tuaj yeem ncav cuag 250-500kg / mm2. Nws muaj cov cua sov tsis kam.
Lub ntsiab lus melting ntawm lub hard anodized zaj duab xis yog siab li 2320k, rwb thaiv tsev zoo heev, Thiab qhov tawg yuam hluav taws xob yog siab npaum li 2000V , uas txhim kho cov corrosion tsis kam. Nws tsis corrode hauv ω = 0.03nacl ntsev pos huab rau ntau txhiab teev. Muaj ntau ntawm micropores hauv cov txheej txheej nyias ntawm oxide zaj duab xis, uas tuaj yeem nqus txhua yam roj nplua. Nws yog qhov haum rau tsim lub cav ntoo lub tog raj kheej lossis lwm yam hnav-resistant. Lub micrropores ntawm oxide zaj duab xis tau muaj peev xwm muaj peev xwm ua tiav thiab tuaj yeem ua xim rau ntau cov xim zoo nkauj thiab zoo nkauj. Tsis yog ferrous hlau los yog lawv cov alloys (xws li aluminium, magnesium thiab lawv cov alloys) tuaj yeem yog anodized.
Taw qhia rau Tshuaj Txhuam Txhuam Txhuas Oxide Phaj
Tshuaj lom neeg Txhuas Oxide Phaj yog cov txheej txheem kho mob uas yog ib feem ntawm cov yeeb yaj kiab uas tsis muaj zog los ua cov yeeb yaj kiab pleev xim rau ntawm nws cov plaub hau thicken lossis ua lwm yam yeeb yaj kiab passivation. Cov tshuaj oxide feem ntau siv oxide cov yeeb yaj kiab yog chromic acid zaj duab xis thiab phosphoric acid zaj duab xis, uas yog nyias nyob rau hauv nqus thiab zoo nyob rau hauv pore sealing.
Kev sib piv ntawm cov yeeb yaj kiab oxide thiab anodexide cov yeeb yaj kiab ntawm Aluminium Phaj
Piv nrog anodizing zaj duab xis ntawm txhuas phaj, Cov tshuaj oxidation zaj duab xis ntawm txhuas phaj yog ntau thinner, nrog qis corrosion tsis kam thiab hardness, thiab tsis yooj yim rau xim, thiab lub teeb tiv taus tom qab xim tsis zoo, yog li kev kho anodizing yog tsuas yog qhia nyob rau hauv cov xim thiab xim sib txuam ntawm cov phaj aluminium.
