Cov oxide txheej uas tsim rau ntawm qhov chaw ntawm tooj liab hlau ua raws li kev tiv thaiv kev tiv thaiv ntxiv oxidation. Nws zoo tiv thaiv kev nkag mus tob dua ntawm cov pa oxygen thiab noo noo, yog li txo tus nqi ntawm corrosion. Qhov kev tiv thaiv ntawm oxidation no ua rau tooj liab zoo heev rau ntau yam kev siv uas raug rau cov ntsiab lus los yog corrosive ib puag ncig yog ib qho kev txhawj xeeb.
Cov txheej tooj liab oxide uas ua rau ntawm qhov chaw ntawm tooj liab hlau yog feem ntau nyias, adherent, thiab ruaj khov. Nws tsis flake tawm yooj yim, kom ntseeg tau tias cov tooj liab hauv qab tseem tiv thaiv. Cov yam ntxwv no ua rau muaj kev ua haujlwm ntev thiab kev cia siab ntawm tooj liab hlau hauv ntau qhov chaw.
Lwm qhov zoo ntawm tooj liab oxidation kuj yog nws lub peev xwm los kho tus kheej. Yog tias cov hlau tooj liab raug rau ib puag ncig uas tsis muaj oxygen, xws li hauv lub kaw lus kaw, cov oxide txheej tuaj yeem maj mam yaj thiab hloov kho lub sijhawm. Cov txheej txheem kho tus kheej no pab tswj kev ncaj ncees ntawm cov hlau tooj liab, ua kom muaj hluav taws xob txuas ntxiv thiab kev ua haujlwm.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias hauv qee qhov xwm txheej, tooj liab hlau tseem tuaj yeem raug oxidation thiab corrosion. Cov yam ntxwv xws li cov av noo siab, raug rau cov tshuaj hnyav, los yog muaj cov sulfur-muaj cov khoom xyaw tuaj yeem ua kom cov txheej txheem oxidation. Tsis tas li ntawd, tooj liab hlau tuaj yeem ua rau muaj kev cuam tshuam ntau dua yog tias nws nkag mus rau hauv kev sib cuag nrog cov hlau tsis sib xws nyob rau hauv lub xub ntiag ntawm electrolyte, ua rau galvanic corrosion.
Txhawm rau txhim kho oxidation tsis kam ntawm tooj liab hlau nyob rau hauv ib puag ncig uas corrosion yog ib qho kev txhawj xeeb, ntau yam kev tiv thaiv tuaj yeem siv tau. Piv txwv li, ib qho kev tiv thaiv txheej los yog plating tuaj yeem ntxiv rau saum npoo ntawm cov hlau, ua ib qho kev thaiv ntxiv tiv thaiv oxidation thiab corrosion. Cov txheej txheem feem ntau suav nrog tin, nyiaj, lossis npib tsib xee, uas muab kev tiv thaiv zoo dua thaum tuav cov khoom zoo ntawm tooj liab.
Nyob rau hauv cov ntsiab lus, tooj liab hlau muaj lub ntuj tsis kam rau oxidation vim yog tsim ntawm ib tug tiv thaiv oxide txheej ntawm nws nto. Qhov kev tiv thaiv no pab tiv thaiv kev xeb ntxiv thiab ua rau lub neej ntev thiab kev cia siab ntawm tooj liab hlau hauv ntau daim ntawv thov. Txawm li cas los xij, hauv qee qhov chaw lossis hauv qee qhov tshwj xeeb, kev tiv thaiv ntxiv yuav tsim nyog los txhim kho nws cov oxidation tsis kam thiab txo qhov kev pheej hmoo ntawm corrosion.
