ABSTRACT:
Material comprising particulate matter is atomized and coated on a surface of an object by delivering the material to a surface of a spinning atomizer from a non-rotating delivery means preferably situated within the volume defined by the atomizer. The material is atomized by being thrust from the atomizer surface and at least a portion of the atomized material impacts the surface being coated. The method is particularly applicable to coating surfaces wherein abrasive material is atomized, since a seal between the non-rotating delivery means and atomizer is not needed, and wherein space limitations are imposed on the configuration of the atomizer. Further, a potential difference may be established between the atomized material and surface to be coated whereby an axial flow of material from the surface of the atomizer may be effected.
