  • Coating process utilizing propelled particles
    Patent number: 4024295
    Abstract: A coating process, whereby particulate material is coated onto a solid substrate surface by exposing the surface in a confined volume containing impact media mixed with the particulate material and propelling the impact media at a velocity sufficient to cause the particulate material to adhere to the surface, is improved by reducing the relative amount of certain undesirable fine particles which may be produced during the coating operation. The improvement is especially useful in a coating process wherein the impact media are small permanent magnet elements which are propelled by a moving magnetic field.
