Kev ntsuam xyuas hlau ntsev yog dab tsi?

Corrosion yog kev puas tsuaj lossis kev puas tsuaj ntawm cov khoom lossis lawv cov khoom los ntawm ib puag ncig. Feem ntau ntawm corrosion tshwm sim nyob rau hauv atmospheric ib puag ncig. Cov huab cua muaj corrosive Cheebtsam thiab corrosive yam xws li oxygen, av noo, kub hloov thiab pa phem. Ntsev tshuaj tsuag corrosion yog ib qho kev sib txuam thiab kev puas tsuaj atmospheric corrosion.

Qhov corrosion ntawm ntsev tsuag rau saum npoo ntawm cov ntaub ntawv hlau yog tshwm sim los ntawm cov tshuaj tiv thaiv electrochemical ntawm cov tshuaj chloride ion uas muaj nyob rau hauv oxide txheej thiab txheej tiv thaiv ntawm cov hlau nto thiab cov hlau sab hauv. Kev ntsuas ntsev ntsev ntawm peb cov khoom siv rooj tog zaum niaj hnub yog ua raws li lub hauv paus ntsiab lus no thiab siv cov khoom siv dag zog tsim los ntawm cov khoom siv tshuaj tsuag ntsev kom pom cov xeb tsis kam ntawm cov khoom. Cov txiaj ntsig ntawm qhov kev sim tuaj yeem txiav txim siab raws li qhov feem pua ​​​​thiab cov tsos ntawm cov rooj tog kho vajtse corrosion.

Nyob rau hauv tib txoj kev sim, lub sijhawm ntev dua nyob rau hauv cov khoom siv tshuaj tsuag ntsev, qhov zoo dua cov xeb kuj ntawm cov khoom. Piv txwv li, ob txheej txheej electroplating yog ua los ntawm kev siv high-purity electroplating, uas ua rau kev tiv thaiv xeb zoo dua.
