Peb hais tias oxidation ntawm aluminium alloy yog anodic oxidation.Txawm hais tias ob qho tib si anodic oxidation thiab electroplating xav tau hluav taws xob, muaj qhov sib txawv tseem ceeb ntawm ob.
Ua ntej saib anodizing, tsis yog tag nrho cov hlau yog haum rau anodizing.Feem ntau, hlau alloys yog anodized, thiab aluminium yog dav siv.Anodic oxidation yog siv cov hlau oxidized (aluminium) ua cov anode thiab ua cov electrolytic oxidation los ntawm cov hluav taws xob tsis tshua muaj hluav taws xob tam sim no los tsim cov yeeb yaj kiab oxide ntom ntom rau ntawm cov khoom siv, uas yog oxide ntawm nws tus kheej hlau.
Electroplating yog txawv.Electroplating yog tsim rau kev kho deg ntawm ntau yam hlau thiab tsis yog hlau.Txhua yam hlau thiab qee cov hlau tsis yog hlau tuaj yeem ua electroplated tsuav lawv tau txais kev kho kom zoo.Txawm hais tias nws yog nplooj nyias, nws tuaj yeem raug electroplated ntev npaum li nws tau kho kom zoo.Sib txawv ntawm anodic oxidation, cov khoom yuav tsum tau plated yog siv los ua cathode, plating hlau yog energized li anode, thiab cov plating hlau muaj nyob rau hauv cov electrolyte nyob rau hauv lub xeev ntawm cov hlau ions.Los ntawm kev them nqi, cov hlau ions ntawm lub anode txav mus rau cathode thiab tso rau ntawm cov khoom siv cathode yuav tsum tau plated.Cov txheej txheem ntau tshaj yog kub, nyiaj, tooj liab, npib tsib xee, zinc, thiab lwm yam.
Nws tuaj yeem pom tau tias aluminium alloy oxidation thiab electroplating yog ob qho tib si kho qhov chaw, uas tuaj yeem ua tiav cov teebmeem zoo nkauj thiab tiv thaiv corrosion.Qhov sib txawv ntawm ob yog tias electroplating yog ntxiv lwm txheej hlau tiv thaiv ntawm qhov chaw ntawm cov khoom qub los ntawm lub cev, thaum anodization yog electrochemically oxidize txheej txheej ntawm cov hlau.
Cov txheej txheem kev kho deg siv rau cov khoom siv aluminium alloy yog anodization, vim tias qhov chaw anodized muaj qhov zoo nkauj zoo nkauj, muaj zog corrosion kuj, thiab kev saib xyuas yooj yim dua.Thiab cov khoom siv aluminium alloy tuaj yeem oxidized thiab xim kom tau txais ntau yam xim uas xav tau.
