Does anyone know of any good process information on this. I understand the concept but wonder how it works in true operation.

           Any help would be appeciated,Joe

RE: electro galvanized wire??

The galvanizing of steel wire, both the hot-dip and electroplating processes, is described in The Making, Shaping and Treating of Steel, 9th Edn., pages 856-860 (1971).
Electro-galvanizing [the term used in the book] has the disadvantage of being a slower process for the same thickness as hot-dip;  hence, a longer tank (100 feet) is required.
Advantages: Electrolytic zinc is more ductile than hot-dip zinc, especially for greater thickness, due to the FeZnn intermetallics formed in the hot-dip process.  Also, the electrolytic thickness is more readily controlled.

For more information on electroplating of zinc on steel, see
'Metal Cleaning,' 'Pickling and Acid Dipping' and 'Zinc Plating' at http://www.metalfinishing.com/WZ/MetalFinishing/guidebooks/show/

ASTM B633-98e1 'Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel' covers zinc electroplating in general, but not onto sheet (see ASTM A591) or wire (no ASTM standard). However, there are at least 5 ASTM specs for hot-dip galvanized wire, e.g., ASTM A854.

Hope this helps,
Ken

Thanks Ken I will give it a look

RE: electro galvanized wire??

Corrosion problem # 3,000,000.
What parameters are we working with; multistrand cable,
single strand 10 gage ? 1/2" cable-treated is a half pound a foot and constant submersion allows 17 - 19 months before
compromise from the 12 ton BREAK rating.
If you want smaller gage go stainless........regardless.
