Abstract
An apparatus and method are provided for coating particles in a rotating container. A cathode forms an electrically conductive inner surface of a side wall of the container. An anode is positioned relative to the cathode so as to permit both the cathode and the anode to be immersed together in an electrically conductive fluid. A motor is connected to the container and arranged to cause the container to rotate so as to generate a centrifugal force. Particles are placed in the container, the container is filled with the electrically conductive fluid, and electrical current is caused to pass from the cathode to the anode through the electrically conductive fluid while the container is rotated. The particles rest against the electrically conductive inner surface of the side wall of the container while the electrical current passes from the cathode to the anode, so as to result in deposition of a coating material from the electrically conductive fluid onto the particles.
