  • Patent number: 7172785
    Abstract: The invention relates to a process for depositing a metal on a material. The process comprises the steps of: immersing the material in deposition solution comprising the metal; inducing a material vibration in the deposition solution having a frequency corresponding to a resonance frequency of the material; including a solution vibration in the deposition solution in a direction non-parallel to the material vibration, said solution vibration having a frequency corresponding to the a resonance frequency of the deposition solution, whereby said metal is deposited onto the material. This process results in deposition of metal from the plating bath on the material in a controlled and substantially uniform thickness.
    Type: Grant

  • Patent number: 6726964
    Abstract: A process for depositing metal on microparticulate comprising immersing microparticulate in an autocatalytic plating bath comprising the metal; inducing ultrasonic vibration in the plating bath at a frequency corresponding to resonance frequency of the microparticulate; and inducing a turbulent vibration signal in the plating bath in a direction non-parallel to the ultrasonic vibration. This process results in the autocatalytic plating bath depositing the metal on the microparticulate with uniform thickness. The microparticulate can be spheres, flakes or microfibers, and can be made from a number of materials, such as synthetic polymers (nylon, Kevlar™, Zylon™, and aramid fibers) and biodegradable compounds. A method is disclosed for coating a surface with metallized microparticulate fibers with an orientation perpendicular to the surface.
