網頁Introduction. Bimetallic corrosion can only occur when two dissimilar metals are in ‘electrical’ contact and are bridged by an electrically conductive liquid. The ‘cell’ produced can result in corrosion to one of the paired metals. This can be an issue when stainless steels are in contact with other metals, depending on the circumstances. 網頁Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence … freeze matzo balls網頁The reaction is: iron (III) oxide + aluminium → aluminium oxide + iron. This shows that aluminium is above iron in the reactivity series.
