Qhov laj thawj yog vim li cas stainless hlau cable cov tais yog thawj qhov kev xaiv hauv kev xaiv hnyav yog lawv cov kev tiv thaiv corrosion zoo heev. Nws siv siab - zoo} Cov khoom zoo stainless hlau xws li 304 thiab 316L, thiab muaj kev nplua nuj nyob hauv cov chromium thiab npib tsib xee. Nws tuaj yeem ua kom nrawm nrawm thiab ruaj khov ua zaj duab xis nyob rau saum npoo. Qhov no oxide zaj duab xis, uas tsuas yog ob peb nanometers tuab, yog zoo li cov hlau loj, txhim kho cov hlau sib xyaw ntawm cov corrosive nruab nrab, zoo heev txhim kho lub corrosive nruab nrab.
Hauv kev cob qhia tshuaj lom neeg, ntau yam kua qaub thiab cov kua nplaum polvosive thiab cov tais diav Corvasive yog yooj yim corroded thiab puas. Nrog kev tiv thaiv ntawm passive zaj duab xis, Stainless hlau cable cov tais tuaj yeem ua kom muaj zog nrog cov yaig ntawm cov kua qaub acid thiab sulfuricic acid thiab sulfuricic acid thiab sulfuricic acid thiab sulfuric acid. Txawm hais tias lawv muaj kev sib cuag nrog siab-}}}}}}}}}}}}}}}}} kev daws teeb meem rau lub sijhawm ntev, lawv tsis nquag ua rau muaj kev ntxhov siab rau corrosion. Piv txwv li, hauv chlor - alkali alkali cov tais diav
Hauv cov chaw tsim khoom thiab cov chaw nyob hauv cov ntug dej hiav txwv, cov ntsev ntsev ntau ua rau muaj kev hem thawj loj loj rau kev xeb ntawm cov choj cable. Chloride ions hauv hiav txwv ntsev yuav txuas ntxiv mus rau saum npoo hlau, ua kom nrawm rau txoj kev corrosion. Txawm li cas los xij, stainless hlau txuas rau ntawm tus kheej -} Kev kho lub peev xwm ntawm zaj duab xis passive. Thaum lub nplaim yog ib nyuag khawb lossis corroding chromium ntsiab yuav sai sai nrog oxygen rau regenerate zaj duab xis, uas txuas ntxiv mus ntxiv ntawm cov ntsev huab cua. Hauv cov chaw xws li cov chaw nres nkoj thiab cov pob tawb, siv cov khoom siv stainless hlau tuaj yeem ua rau muaj cov haujlwm tseem ceeb ntawm cov chaw tseem ceeb xws li cov khoom siv tseem ceeb xws li cov khoom siv hluav taws xob.
