Abstract: A new article of manufacture comprising an aluminum substrate has at least one surface coated with a lubricating material. The lubricating material is preferably a dielectric hydrocarbon deposited in particulate form by the method of electrostatically charging the particles so that they mutually repel one another, maintaining a quiescent cloud of such charged particles adjacent the surface to be lubricated, and depositing and distributing the charged particles onto the surface substantially entirely by electrostatic forces. The particles preferably have an average diameter of less than ten microns and are deposited to cover from about one percent to about fifteen percent of the surface in an amount of from about four milligrams per square foot to about 24 milligrams per square foot.

Abstract: Apparatus for generating and substantially uniformly electrostatically dispersing very finely divided lubricating particles onto the surface of an electrically conductive substrate. In this apparatus, lubricant material is atomized into a spray of particles of various sizes. Larger particles are removed from the spray by gravity, airflow and other forces. The remaining cloud of extremely small particles is delivered to a housing. The housing is preferably constructed from electrically non-conductive material and is structured to maintain the cloud of small particles in a substantially quiescent suspension between electrodes spaced from the conductive substrate within the housing. An ionization discharge is maintained by a voltage differential between the electrodes and the substrate to electrically charge the small particles in the cloud for deposition substantially entirely by electrostatic forces.

Abstract: Apparatus generates and substantially uniformly electrostatically deposits very finely divided lubricating particles onto the surface of an electrically conducting substrate. A lubricant material is sheared into droplets of various sizes. The larger particles are filtered out of a flow of particles by gravity, baffles, and other forces leaving only a cloud of extremely small particles to be deposited. Deposition occurs within a housing that includes a plurality of sections arranged longitudinally on at least one side of the substrate and includes electrode means transversely positioned in each such section. The cloud of particles is uniformly provided to each of a plurality of longitudinal sections of the substrate and permitted to drift or migrate relatively slowly between the electrodes and the substrate. The particles in the cloud are electrostatically charged by high voltage applied to the electrodes and deposited on the surface of the substrate as a uniform dispersion of spaced particles of lubricant.

Abstract: A new method for generating and substantially uniformly electrostatically dispersing very fine spheroidally shaped lubricating particles onto the moving surface of a metal or other electrically conductive substrate. A lubricant material in its liquid state is drawn by airflow through a small venturi orifice where it is sheared into droplets of various sizes. Larger droplets are filtered out of the continuing post-venturi airflow by gravity, baffles, airflow forces and/or inertia effects leaving only a mist cloud of extremely small spheroid particles which are then migrated within a charged plasma so as to transfer electrical charge thereto in sufficient quantities to achieve a desired uniform high charge/mass ratio and thus insure an eventually uniform electrostatic dispersion of substantially all the spheroids over the substrate surface.
