<p>13 Ferrous alloy strip, wire, pipe or formed articles, is galvanized using hot dip in a molten zinc-aluminum bath. Enhanced corrosion resistance is achieved by precoating the ferrous alloy surface with a metal which is wettable by and reacts with the zinc-aluminum bath, preferably nickel. The nickel precoat is preferably formed by electroplating in line with the galvanizing step and enables cold line galvanizing to be used.</p> |
