Raws li cov lus ceeb toom, nrog rau kev txhim kho txuas ntxiv ntawm tib neeg, qee zaum hauv peb lub neej peb feem ntau siv cov yeeb nkab steel hlau, yog li thaum peb pom tias qhov chaw ntawm cov yeeb nkab steel hlau tsis huv, yog dab tsi? Hauv qhov no, yuav daws tau li cas? Ntawm no peb qhia koj yuav ua li cas ntxuav cov khoom saum npoo ntawm alloy steel yeeb nkab strip steel nyob rau hauv qhov teeb meem no, cia peb saib.
Thawj thawj zaug hauv peb lub neej niaj hnub, tib neeg feem ntau siv cov yeeb nkab steel hlau, thiab qee cov ntaub ntawv feem ntau tshwm sim ntawm nws qhov chaw. Peb yuav ntxuav thiab nto nws tsis tu ncua. Rau alloy steel yeeb nkab ca steel, qhov qis ntawm qhov roughness, qhov smoother ntawm qhov chaw, qhov nyuaj ntawm txawv teb chaws teeb meem, qhov nyuaj dua nws yog los txo qhov kev pheej hmoo ntawm corrosion hauv zos. Yog li ntawd, lub tiaj tus steel yuav tsum tau siv los tshuab lub nto.
Kev tu saum npoo ntawm lub tiaj tus hlau ntawm ob lub alloy steel yeeb nkab yog qhov tseem ceeb heev. Kev ntxuav zaum kawg yuav tsum tau ua tib zoo. Cov kua qaub residual tom qab passivation txhawb cov tshuaj tiv thaiv cathodic thiab rhuav tshem cov yeeb yaj kiab, yog li cov hlau tiaj tiaj tau qhib thiab qhov kev tiv thaiv corrosion kuj txo qis heev. Thiab alloy steel yeeb nkab ca steel passivation zaj duab xis belongs rau lub thermodynamic metastable qauv uas inhibits qhov ncauj tiv thaiv efficiency thiab ib puag ncig xov xwm. Hauv kev siv, nws yuav tsum tau ntxuav tsis tu ncua kom tshem tawm cov khoom tsis zoo uas txuas nrog rau lub sijhawm ntev. Thaum kawg, cov no yog txhua yam hais txog yuav ua li cas nrog cov ntsiab lus ntawm cov yeeb nkab steel hlau uas tiaj tus thiab huv si.
