Qhov sib txawv tseem ceeb ntawm anodic thiab cathodic polarization yog tias anodic polarization yog hais txog kev hloov ntawm electrode lub peev xwm nyob rau hauv txoj kev zoo whereas cathodic polarization yog hais txog kev hloov ntawm electrode lub peev xwm nyob rau hauv qhov kev coj tsis zoo.
Anodic thiab cathodic polarization yog ob txoj kev siv hluav taws xob hluav taws xob uas tseem ceeb hauv kev txo qis corrosion ntawm cov hlau nto. Anodic polarization yog qhov ntxeev ntawm cathodic polarization.
Anodic Polarization yog dab tsi?
Anodic polarization yog cov txheej txheem electrochemical ntawm kev hloov cov electrode lub peev xwm nyob rau hauv txoj kev zoo. Qhov no tuaj yeem ua tau los ntawm qhov tam sim no ntws hla lub electrode-rau-electrolyte interface, zoo ib yam li electrode polarization uas cuam tshuam nrog electrochemical oxidation lossis anodic cov tshuaj tiv thaiv. Qhov ntawd txhais tau hais tias, kev hloov pauv ntawm qhov pib anode muaj peev xwm ua rau muaj qhov ntws tam sim no uas cuam tshuam rau thaj tsam ze ntawm qhov chaw anode.
Feem ntau, lo lus polarization yog qhov kev hloov pauv ntawm lub peev xwm los ntawm lub xeev ruaj khov raws li qhov tshwm sim ntawm qhov kev hla tam sim no. Tsis tas li ntawd, peb tuaj yeem txhais nws raws li qhov kev hloov pauv ntawm lub peev xwm ntawm lub tshuab hluav taws xob thaum lub sij hawm electrolysis, zoo ib yam li cov txheej txheem uas lub peev xwm ntawm anode ua nobler tshaj qhov muaj peev xwm rov qab.
Kev siv loj ntawm anodic polarization yog ntsuas thiab tiv thaiv qhov chaw tiv thaiv corrosion. Peb kuj tuaj yeem siv nws los txiav txim siab txog thaj chaw muaj peev xwm uas cov ntaub ntawv muaj kev cuam tshuam rau corrosion sai. Peb tuaj yeem yooj yim polarize anodic nto los ntawm kev tsim ib txheej nyias, impervious oxide. Txawm li cas los xij, qhov kev tsim zaj duab xis no yuav tsum tau pab ntau ntxiv nrog rau kev sib ntxiv ntawm anodic corrosion inhibitors xws li chromate thiab nitrite.
Cathodic Polarization yog dab tsi?
Cathodic polarization yog cov txheej txheem electrochemical ntawm kev hloov cov electrode lub peev xwm hauv qhov tsis zoo. Txoj kev tswj kev tiv thaiv corrosion no yuav suav nrog kev hloov lub peev xwm ntawm cov anode lossis cathode lossis qee zaum ob qho tib si. Yog li ntawd, cov txheej txheem no txo qhov poob ntawm cov hlau, thiab nws tuaj yeem txo qhov kev tsav tsheb ntawm cov tshuaj tiv thaiv corrosion. Kev tiv thaiv los ntawm kev xeb los ntawm txoj kev no tuaj yeem tau txais thaum qhov sib txawv muaj peev xwm raug txo kom tsawg kawg nkaus tus nqi.

Qhov tseem ceeb, cov tshuaj tiv thaiv cathodic tshwm sim thaum muaj qee qhov peev xwm ntawm cathode. Ntawm no, hydrogen gas npuas los ntawm cathode uas qhia txog kev txo cov tshuaj tiv thaiv.
Qhov txawv ntawm Anodic thiab Catholic Polarization yog dab tsi?
Anodic polarization yog qhov ntxeev ntawm cathodic polarization. Qhov sib txawv tseem ceeb ntawm anodic thiab cathodic polarization yog tias anodic polarization yog hais txog kev hloov pauv ntawm electrode lub peev xwm nyob rau hauv txoj kev zoo thaum cathodic polarization yog hais txog kev hloov ntawm electrode lub peev xwm nyob rau hauv qhov tsis zoo.
Ntxiv mus, anodic polarization yog cov tshuaj tiv thaiv oxidation whereas cathodic polarization yog txo cov tshuaj tiv thaiv. Anodic polarization yog siv los ntsuas thiab tiv thaiv qhov chaw tiv thaiv corrosion thaum cathodic polarization yog siv los tiv thaiv qhov chaw corrosion thaum qhov sib txawv ntawm qhov sib txawv yog txo kom tsawg kawg nkaus tus nqi.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm anodic thiab cathodic polarization hauv daim ntawv tabular.
Summary – Anodic vs Cathodic Polarization
Anodic polarization yog qhov ntxeev ntawm cathodic polarization. Qhov sib txawv tseem ceeb ntawm anodic thiab cathodic polarization yog tias anodic polarization yog hais txog kev hloov pauv ntawm electrode lub peev xwm nyob rau hauv txoj kev zoo thaum cathodic polarization yog hais txog kev hloov ntawm electrode lub peev xwm nyob rau hauv qhov tsis zoo.
