Sodium, in my opinion, is not (or should not be) your main concern. Sodium ions are very active metallic cations so they will not compete against most metals. Anions, such as chlorides or fluorides should play the important role in corrosion because they are eager of metal to combine chemically. Both of them require a thick nickel or a combined copper+nickel plating. Another option would be to coat with stainless steel.
