Bimetallic corrosion, tseem hu ua galvanic corrosion, yog cov txheej txheem electrochemical uas ob lub hlau sib txawv tau muab tso rau hauv ib qho kev daws teeb meem thiab ob lub hlau txuas nrog hluav taws xob.
Hauv cov txheej txheem no, ib qho hlau tiv thaiv thiab lwm yam corrodes. Nws muaj peev xwm tiv thaiv galvanic corrosion los ntawm kev xyaum ntau txoj cai.
Cov ntaub ntawv uas muaj peev xwm corrosion zoo sib xws yuav tsum raug xaiv, kev sib txuas hluav taws xob yuav tsum tau tawg los ntawm kev rwb thaiv tsev, thiab thaum kawg, coatings siv rau ob qho khoom siv.
Cov txheej txheej zoo tuaj yeem tiv thaiv cov hlau los ntawm tev tawm ntawm cathode lossis anode, yog li txhim kho nws cov corrosion kuj thiab zoo tiv thaiv ob qho tib si hlau.
