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.
