Qhov sib txawv tseem ceeb ntawm electroplating thiab anodizing yog tias electroplating yog txheej txheem ntawm txheej ib hlau ntawm lwm qhov hlau qhov chaw anodizing yog txheej txheem ntawm kev nce cov thickness ntawm cov txheej txheem oxide nyob rau saum npoo ntawm cov hlau.
Nyob rau hauv cov txheej txheem ntawm electroplating, cov khoom ntawm kev txaus siab yog siv raws li cathode ntawm ib tug electrochemical cell thaum nyob rau hauv cov txheej txheem anodizing, cov khoom ua raws li anode, uas ua rau nws lub npe, anodizing.
Electroplating yog dab tsi?
Electroplating yog txheej txheem kev lag luam thiab tshuaj ntsuam xyuas uas peb tuaj yeem txheej ib lub hlau ntawm lwm cov hlau siv hluav taws xob. Cov txheej txheem no suav nrog lub xov tooj ntawm tes electrochemical uas muaj ob lub electrodes uas yog raus rau hauv tib lub electrolyte. Nyob rau hauv cov txheej txheem no, peb yuav tsum tau siv cov khoom (uas peb tab tom yuav coated nrog cov hlau) raws li lub cathode. Yog li ntawd, cov anode yog cov hlau uas peb yuav siv rau ntawm cathode, los yog nws tuaj yeem yog inert electrode.

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 raug 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 tiv thaiv corrosion.
Anodizing yog dab tsi?
Anodizing yog txheej txheem electrochemical uas electrolytic passivation tshwm sim. Txoj kev no yog qhov tseem ceeb hauv kev ua kom cov tuab ntawm cov txheej txheem oxide nyob rau saum npoo ntawm cov hlau. Cov txheej txheem no muaj npe xws li vim tias qhov uas peb tab tom kho ua raws li anode hauv electrochemical cell. Cov txheej txheem ntawm anodizing tuaj yeem ua rau muaj kev tiv thaiv corrosion thiab hnav tsis kam ntawm cov khoom. Tsis tas li ntawd, nws muab cov khoom nrog adhesion zoo dua rau cov xim primers thiab cov nplaum ntau dua li cov hlau liab qab.

Ntxiv mus, cov txheej txheem anodizing yog qhov tseem ceeb hauv kev tiv thaiv kev sib tsoo ntawm cov khoom sib txuas thiab ua cov yeeb yaj kiab dielectric rau electrolytic capacitors. Feem ntau, cov anodic films yog siv los tiv thaiv aluminium alloys thiab titanium, zinc, magnesium, niobium thiab zirconium.
Dab tsi yog qhov zoo sib xws ntawm Electroplating thiab Anodizing?
- Ob leeg yog cov txheej txheem electrochemical.
- Cov tswv yim no koom nrog kev tso cov khoom ntawm cov hlau nto.
Qhov txawv ntawm Electroplating thiab Anodizing yog dab tsi?
Electroplating thiab anodizing yog cov txheej txheem electrochemical tseem ceeb. Qhov sib txawv tseem ceeb ntawm electroplating thiab anodizing yog tias electroplating yog txheej txheem ntawm txheej ib lub hlau ntawm lwm qhov hlau qhov chaw anodizing yog txheej txheem ntawm kev ua kom cov thickness ntawm cov txheej txheem oxide nyob rau saum npoo ntawm cov hlau.
Hauv qab infographic tabulates qhov sib txawv ntawm electroplating thiab anodizing.
Summary – Electroplating vs Anodizing
Ob qho tib si electroplating thiab anodizing txheej txheem koom nrog kev tso cov khoom ntawm cov hlau. Ob leeg yog cov txheej txheem electrochemical. Qhov sib txawv tseem ceeb ntawm electroplating thiab anodizing yog tias electroplating yog txheej txheem ntawm txheej ib lub hlau ntawm lwm qhov hlau qhov chaw anodizing yog txheej txheem ntawm kev ua kom cov thickness ntawm cov txheej txheem oxide nyob rau saum npoo ntawm cov hlau.
