Abstract
A method for coating particulate substrate materials is provided which comprises (a) combining particles and an electrolyte in an imperforate container; (b) vibrating the container to generate a fluidized bed of particles in the electrolyte; and (c) electrochemically depositing a coating on the particles from reactants in the electrolyte. An apparatus for coating particles is also provided which comprises an imperforate container for receiving particles to be coated and an electrolyte and a device for generating a fluidized bed in the container, the device being operatively associated with the container.
