Electro-Polishing VS Chemical Polishing

Electrolytic polishing yog hais txog anodic oxidation ntawm cov khoom hlau nyob rau hauv ib qho kev daws ntawm ib qho piv txwv kom tau ib tug du, ci ntsa iab. Cov hlau qhov chaw yog muab tso rau hauv ib lub da dej electrolytic, thiab ncaj qha tam sim no yog siv los tsim kev xaiv anodic dissolution, uas txo cov microscopic roughness ntawm cov hlau nto thiab ua tiav cov nyhuv ntawm kev ua kom lub ntsej muag ci ntawm lub workpiece. Electrolytic polishing tuaj yeem yog qhov kev npaj nto ua ntej plating thiab ua tiav ntawm cov hlau nto tom qab plating. Electrochemical polishing yog tsim rau cov hlau tsis-ferrous thiab lwm yam ib-theem alloys uas tsis tshua muaj hardness, xws li txhuas alloys, austenitic stainless hlau, siab manganese hlau, thiab lwm yam. cov duab inhomogeneous. Qhov loj microscopic segregation thiab non-metallic inclusions muaj nyob rau hauv cov hlau matrix.

Electrochemical polishing tuaj yeem siv rau ntau lub sijhawm los hloov cov txheej txheem txheej txheem polishing, tshwj xeeb tshaj yog rau cov khoom uas muaj cov duab nyuaj uas nyuaj rau kev ua haujlwm. Electrochemical polishing muaj qhov zoo ntawm cov luster ntev, kev ua haujlwm siab thiab tus nqi qis. Txawm li cas los xij, electrochemical polishing kuj tseem muaj qhov tsis xws luag, xws li tsis tuaj yeem tshem tawm lossis npog qhov khawb tob thiab lwm yam tsis xws luag, kuj tsis tuaj yeem tshem tawm cov khoom tsis yog hlau hauv cov hlau. Nyob rau hauv multiphase alloys, yog tias ib qho ntawm cov theem tsis yooj yim yaj los ntawm anode, nws yuav cuam tshuam qhov zoo ntawm electrolytic polishing. Qhov no nyob ntawm qhov ceev tam sim no, thiab cov qauv metallographic nyob ntawm qhov chaw qub, qhov kub thiab txias.

Tshuaj polishing yog lwm txoj kev ua tiav rau cov hlau nto. Nws chemically etches hlau qhov chaw nyob rau hauv ib qho kev daws teeb meem nyob rau hauv ib tug txheej txheem uas cov hlau nto yog etched thiab leveled los ntawm cov tshuaj kom tau ib tug brighter nto. Tshuaj polishing tuaj yeem siv rau saum npoo ntawm qhov chaw xws li cov twj paj nruag, aluminium reflectors lossis plating rau kho kom zoo nkauj. Piv nrog electrolytic polishing, qhov zoo ntawm cov tshuaj polishing yog: tsis muaj hluav taws xob sab nraud, tuaj yeem ua haujlwm nrog ntau cov duab, kev ua haujlwm siab, tab sis qhov zoo ntawm cov tshuaj polishing feem ntau qis dua li ntawm electrolytic polishing, nws cov kev npaj thiab rov tsim dua tshiab. ntawm nws cov kev daws teeb meem yog qhov nyuaj dua, thiab feem ntau precipitate nitrogen oxides thiab lwm yam gases txaus ntshai, ua phem rau ib puag ncig.
