(a) From the galvanic series (Table 16.2), cite three metals or alloys that may be used to galvanically protect 304 stainless steel in the active state.

(b) As Concept Check 16.4(b) notes, galvanic corrosion is prevented by making an electrical contact between the two metals in the couple and a third metal that is anodic to the other two. Using the galvanic series, name one metal that could be used to protect a copper–aluminum galvanic couple.
