Galvanic Corrosion Mechanism When two different metals with different … WebJan 8, 2002 · Galvanic Corrosion. Galvanic corrosion is an electrochemical process, which involves flow of electric current. It occurs due to the galvanic effect caused by the contact of two dissimilar metals in an electrically conductive liquid. The following are the three major conditions for galvanic corrosion:
WebCause Of Galvanic Corrosion. Often, two different types of metal are in contact with each other. When this occurs, there is a possibility of galvanic corrosion due to the different atomic properties of the metals. Certain metals are more prone to undergo galvanic corrosion, but all metals can experience this phenomenon.
WebCorrosion occurs due to the formation of electrochemical cells. In order for the corrosion reaction to occur five things are necessary. If any of these factors are eliminated, galvanic corrosion will not occur. THIS IS THE KEY TO CORROSION CONTROL!
