Engineering Materials Week 12-Interactivity 17.4 (a) From the galvanic series cite three metals or alloys that may be used to galvanically protect nickel in the active state. Tin‚ lead and cast iron may be used. (b) Sometimes galvanic corrosion is prevented by making an electrical contact between both metals in the couple and a third metal that is anodic to these other two. Using the galvanic series‚ name one metal that could be used to protect a copper-aluminum galvanic couple. Zinc may be used
