Qhov sib txawv tseem ceeb ntawm electroforming thiab electroplating yog tias nyob rau hauv cov txheej txheem electroforming, peb tab tom ua ib qho khoom sib cais whereas, hauv cov txheej txheem electroplating, peb tau tso cov hlau rau ntawm cov khoom uas twb muaj lawm.
Txawm hais tias ob qho tib si cov txheej txheem no yog cov txheej txheem kev lag luam uas siv hluav taws xob los ua lub zog loj, muaj qhov sib txawv ntawm electroforming thiab electroplating.
Electroforming yog dab tsi?
Electroforming yog txheej txheem kev lag luam uas cov khoom tuaj yeem tsim tau siv txoj kev electrodeposition siv rau ntawm mandrel. Lub mandrel yog ib qho qauv uas muaj txiaj ntsig zoo hauv kev lag luam. Mandrels yog xim hlau thiab conductive qauv. Peb yuav tsum tau kho cov mandrels los tsim ib txheej txheej txheej. Yog tias tsis yog, peb tuaj yeem chemically passivate los txwv nws cov electroform adhesion. Qhov no tso cai rau cov txheej txheem sib cais tom qab ntawm electroform los ntawm mandrel. Txawm li cas los xij, cov khoom siv tsis muaj hluav taws xob ua los ntawm iav, silicon thiab yas xav tau qhov kev tso tawm ntawm cov txheej txheem ua ntej electrodeposition. Peb tuaj yeem ua cov txheej txheem no tso rau hauv tshuaj lom neeg lossis los ntawm cov txheej txheem nqus tsev vacuum. Feem ntau, sab nrauv ntawm mandrel ua rau sab hauv ntawm daim ntawv.
Daim duab 01: Electroforming
Cov txheej txheem Electroforming suav nrog kev dhau ntawm qhov ncaj qha tam sim no los ntawm cov electrolyte uas muaj cov ntsev ntawm cov hlau uas tau electroformed. Hauv cov txheej txheem no, lub anode yog cov khoom hlau uas peb siv, thiab cathode yog mandrel. Thaum lub sij hawm tus txheej txheem, cov khoom hlau yog tso rau ntawm mandrel nto, thiab nws tseem mus txog rau thaum lub siab xav electroform thickness yog tsim. Tom qab ntawd, lub mandrel no tuaj yeem sib cais los ntawm txoj kev tsis zoo, los ntawm kev yaj tawm lossis los ntawm kev sib cais nws.
Electroplating yog dab tsi
Electroplating yog txheej txheem kev lag luam uas txheej txheej ntawm ib lub hlau ntawm lwm cov hlau ua tiav siv hluav taws xob. Cov txheej txheem kev lag luam no suav nrog cov hluav taws xob hluav taws xob uas muaj ob lub electrodes uas tau muab tso rau hauv tib lub electrolyte. Ntxiv mus, peb yuav tsum tau siv cov khoom (uas peb yuav coated nrog hlau) raws li cov cathode, thiab cov anode yog cov hlau uas peb yuav mus thov rau lub cathode, los yog nws yuav ua tau ib tug inert electrode.
Daim duab 02: Electroplating
Thaum cov txheej txheem ntawm electroplating, lub kaw lus yog thawj zaug muab hluav taws xob los ntawm sab nraud, uas ua rau cov hluav taws xob hauv electrolyte dhau los ntawm anode mus rau cathode. Lub cathode muaj tshem tau electrons. Hauv cov tshuaj electrolytic, muaj cov hlau ions uas tuaj yeem txais cov khoom siv hluav taws xob. Tom qab ntawd, cov hlau ions tau txo qis thiab ua hlau atoms. Tom qab ntawd, cov hlau atoms tuaj yeem tso rau ntawm qhov chaw ntawm cathode. Tag nrho cov txheej txheem no hu ua "plating".
Txawm li cas los xij, peb yuav tsum ua tib zoo xaiv cov electrolyte. Yog tias cov electrolyte muaj lwm cov hlau ions uas tuaj yeem tso nrog rau qhov xav tau hlau ion, plating yuav tsis raug. Yog li ntawd, lub cathode uas cov hlau yog plated yuav tsum huv si thiab tsis muaj kab mob. Txwv tsis pub, lub plating ua tsis ncaj. Cov kev siv loj ntawm cov txheej txheem electroplating yog rau kev kho kom zoo nkauj lossis kev tiv thaiv corrosion.
Qhov txawv ntawm Electroforming thiab Electroplating yog dab tsi?
Txawm hais tias ob qho tib si electroforming thiab electroplating txheej txheem yog cov txheej txheem kev lag luam uas siv hluav taws xob los ua lub zog tseem ceeb, muaj ntau qhov sib txawv ntawm lawv. Qhov sib txawv tseem ceeb ntawm electroforming thiab electroplating yog tias nyob rau hauv cov txheej txheem electroforming, peb tab tom ua ib qho khoom cais, whereas, nyob rau hauv cov txheej txheem electroplating, peb tau tso cov hlau rau ntawm cov khoom uas twb muaj lawm. Ntxiv rau qhov sib txawv no, lwm qhov sib txawv ntawm electroforming thiab electroplating yog tias electroforming ua ib daim qauv ntawm cov khoom, thaum electroplating tuaj yeem pab ntxuav qhov chaw lossis hloov qhov chaw ntawm cov khoom.
Cov hauv qab no infographic teev qhov sib txawv ntawm electroforming thiab electroplating hauv daim ntawv tabular rau ib sab sib piv.
Summary - Electroforming vs Electroplating
Electroforming yog txheej txheem kev lag luam uas cov khoom tuaj yeem tsim tau siv txoj kev electrodeposition siv rau ntawm mandrel. Electroplating yog txheej txheem kev lag luam uas cuam tshuam nrog txheej ib qho hlau ntawm lwm cov hlau siv hluav taws xob. Qhov sib txawv tseem ceeb ntawm electroforming thiab electroplating yog tias electroforming tsim ib yam khoom tshiab, thaum cov txheej txheem electroplating hloov cov khoom uas twb muaj lawm.
