  • Cold dry plating process for forming a polycrystalline structure film of zinc-iron by mechanical projection of a composite material
    Patent number: 6015586
    Abstract: High efficiency cold dry plating method for forming an important and highly adherent polycrystalline structured zinc alloy film on metallic substrates by mechanical projection of a composite material.High efficiency cold dry plating method using a composite material described as iron nuclei particles encapsulated by zinc alloy, where the composite material contains 45 to 80% of zinc.Cold dry plating process giving improved yield and short treatment time with high amount of zinc strongly adherent on metallic surfaces.
