DeKalb Metal Finishing’s Zinc Iron process takes advantage of some of the most recent plating advancements for depositing Zinc alloy coatings from an alkaline electrolyte. Deposits typically contain 0.4-0.8% by weight iron, are extremely fine grained, very low stressed, and burn free, even at unusually high current densities. Deposits are also uniformly bright, and mesh perfectly with trivalent passivates.
Additionally, three additives are used to ensure maximum flexibility and versatility. These additives provide grain refinement, deposit brightness, and determine the maximum limiting current density and have been specially synthesized to provide stability. Additionally, these additives maintain the iron in a state so that it can be co-deposited, thereby creating an alloy coating and ensure the proper iron concentration of the plating bath.
Product Benefits Of Zinc-Iron Plating
• Highly protective, bright, burn-free deposits can be applied, even at very high current densities.
• Deposits are extremely low stressed and blister free.
• Excellent covering power and uniformity of plate distribution.
• Less variation of iron content as a function of current density than with competitive processes.
