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.
