Electrochemical polishing yog txheej txheem uas cov khoom ua haujlwm polished ua haujlwm raws li cov anode thiab cov hlau tsis huv ua haujlwm ua cathode. Ob lub electrodes yog immersed nyob rau hauv ib tug electrochemical polishing tank thiab ib tug ncaj qha tam sim no yog siv los xaiv yaj lub anode, ua rau lub brightness ntawm lub anode. Cov txheej txheem no yog qhov txawv ntawm cov txheej txheem electroplating.
Electrochemical polishing mechanism - viscous zaj duab xis txoj kev xav: Polishing feem ntau yog los ntawm kev sib xyaw ua ke ntawm cov txheej txheem anode electrode thiab nto phosphate zaj duab xis. Cov hlau ions yaj los ntawm anode daim ntawv phosphate hydrochloric acid uas tsis muaj solubility, siab viscosity, thiab tsawg diffusion tus nqi nrog phosphoric acid nyob rau hauv cov tshuaj polishing, thiab maj mam sib sau nyob ze ntawm lub anode, adhering rau saum npoo ntawm lub anode thiab tsim ib tug heev viscous electrolyte. txheej. Lub mucosa nrog kev ua kom siab siab thiab tsis zoo yog faib tawm ntawm lub tshuab loj me, uas cuam tshuam rau kev faib tawm ntawm cov anode. Nws yog pom tseeb hais tias lub thickness ntawm lub mucosa yog me me nyob rau hauv lub micro protrusions tshaj nyob rau hauv lub depressions, uas ua rau ntau dua tam sim no ceev thiab sai dissolution tus nqi ntawm lub protrusions. Nrog rau qhov ntws ntawm mucosa thiab kev hloov pauv tsis tu ncua ntawm concave thiab convex txoj haujlwm, qhov ntxhib nto maj mam flattens. Stainless hlau nto yog polished kom ua tau ib tug heev du thiab glossy tsos.
Los ntawm qhov no, nws tuaj yeem pom tau tias qhov concentration thiab viscosity ntawm cov tshuaj yog qhov tseem ceeb, tshwj xeeb tshaj yog cov viscosity ntawm cov tshuaj, uas feem ntau tshwm sim nyob rau hauv qhov tseeb tias txawm hais tias cov kev daws teeb meem tshiab polishing ua tau raws li qhov xav tau ntawm cov ntsiab lus, nws tsis tuaj yeem polished. kiag li vim lub viscosity tseem tsis tau raws li qhov yuav tsum tau. Tsuas yog tom qab ib lub sijhawm ntawm electrolysis nws tuaj yeem pib polishing zoo. Tshwj xeeb tshaj yog lub interface concentration thiab viscosity ntawm cov tshuaj thiab cov khoom ua si ib qho tseem ceeb luag hauj lwm nyob rau hauv polishing, uas yog vim li cas nws yuav tsum tau hais tias cov dej saum npoo ntawm cov khoom yuav tsum uniform ua ntej nkag mus rau polishing tov. Txwv tsis pub, qhov tsis sib xws ntawm cov yeeb yaj kiab dej ntawm qhov chaw ntawm qhov chaw yuav ua rau lub cev tsim ntawm cov mucosa thiab ua rau lub zos corrosion. Nws yog qhov zoo tshaj plaws los ua kom qhuav qhov chaw tom qab ntxuav thiab muab tso rau hauv qhov zawj sai sai, yog li ntawd tom qab hluav taws xob polishing, nto corrosion tuaj yeem zam tau.
Electro chemical polishing tsis tuaj yeem hloov kho txhua yam polishing. Electrochemical polishing tsuas yog muaj kev soj ntsuam me me thiab qib theem ntawm cov hlau nto. Macro leveling cia siab rau txhua yam polishing. Electrochemical polishing yog tshwj xeeb tshaj yog rhiab heev rau qhov tsis sib xws ntawm cov khoom siv tshuaj lom neeg muaj pes tsawg leeg thiab microscopic segregation, uas feem ntau ua rau muaj kev puas tsuaj loj ntawm cov hlau substrate thiab cov khoom tsis yog hlau. Qee lub sij hawm, cov xwm txheej tsis zoo ntawm cov hlau tsis sib xws, qhov loj me thiab cov qauv ntawm cov hlau, dov cov cim, kev paug los ntawm cov ntsev los yog oxides, cov kua qaub ntau dhau, thiab quenching tuaj yeem cuam tshuam rau electrochemical polishing. Cov teeb meem no feem ntau yuav tsum tau them nyiaj los ntawm kev siv tshuab polishing thaum ntxov.
Piv nrog rau kev siv tshuab polishing, electrochemical polishing tuaj yeem muaj qhov zoo hauv qab no:
1. Cov khoom muaj xim zoo ib yam sab hauv thiab sab nraud, huv si thiab ci, ci ntsa iab ntev, thiab pom meej contour.
2. Cov xov burrs yaj thiab poob tawm thaum lub sij hawm electrolysis, thiab cov pob txha xoob yog sib npaug ntawm cov xov kom tsis txhob tom thiab tuag.
3. Kev tiv thaiv corrosion ntawm polished nto yog txhim khu kev qha.
4. Piv nrog rau cov neeg kho tshuab polishing, cov kev ua haujlwm ntau lawm yog siab thiab cov nqi tsim khoom tsawg.
