.... In Table 12.2 (the galvanic series of common alloys) stainless steels occupy two places, depending on whether they are passive or not. Titanium alloys may be passive under special conditions. Fig. 12.8 Above a critical anode potential, certain materials become passive. Their corrosion rate drops...

... Corrosion of Zinc The ability of zinc to galvanically protect steel, because of its more negative standard electrochemical potential, has given this metal a wide variety of application ( Ref 1 , 13 , 68 – 80 ). Although zinc by itself is available in sheet, plate, strip, and pressure die castings...

Galvanized steel, carbon steel, and aluminum will corrode more readily than the stainless, and this corrosion is aggravated by galvanic contact. The resulting corrosion products are also harmful as well as unsightly...
