A hauv av yog ib qho electrode array uas tau teeb tsa hauv qab hauv av muab tawm ib txoj kev uas tsis tshua muaj siab rau hauv av . Nyob rau hauv cov nqe lus ntawm kev tiv thaiv cathodic , qhov no hauv av hais txog anodes 'kev npaj hauv dej los yog hauv av , uas muab txoj hauv kev rau kev tiv thaiv tam sim no tawm ntawm anodes mus rau hauv ib qho electrolyte.

Hais txog qhov no, lub txaj anode yog dab tsi?

Ib anode txaj yog ib tug series ntawm electrodes ntsia nyob rau hauv ib tug electrolytic ib puag ncig los muab cathode tiv thaiv corrosion los ntawm kev pab raws li ib tug electrolytic cell tivthaiv.

Qhov thib ob, ob hom kev tiv thaiv cathodic yog dab tsi? Muaj ob hom kev tiv thaiv cathodic , ua galvanic kev tiv thaiv thiab impressed tam sim no. Ib galvanic cathodic tiv thaiv system rau USTs, muaj cov sacrificial anode (s) tsau rau UST thaum lub sij hawm tsim UST, thiab muab cov kev qhia tshwj xeeb rau cov chaw soj ntsuam uas tau teeb tsa ze ntawm qhov av.

Ib yam li ntawd, koj tuaj yeem nug, kev tiv thaiv cathodic yog dab tsi thiab nws ua haujlwm li cas?

Cathodic tiv thaiv tiv thaiv corrosion los ntawm kev hloov tag nrho cov anodic (active) qhov chaw ntawm cov hlau nto rau cathodic (passive) qhov chaw los ntawm kev muab hluav taws xob tam sim no (lossis dawb electrons) los ntawm lwm qhov chaw. Feem ntau qhov no yuav siv sij hawm daim ntawv ntawm galvanic anodes, uas yog active dua hlau.

Cathodic txhais li cas?

1. cathodic - ntawm lossis ntawm lossis cuam tshuam rau cathode; " cathodic Kev xa tawm ntawm cov hlau "anodal, anodic - ntawm lossis ntawm lossis cuam tshuam rau anode.
