The invention provides a method and system for electrolytically coating an article. The method includes providing an article to be coated and disposing the article in an electrolytic cell. The cell includes an anode, a cathode in operable communication with the article, and an electrolyte bath. During electrolysis, the electrolyte bath comprises cobalt ions, phosphorous acid, and tribological particles selected from the group consisting of refractory materials, solid lubricants and mixtures thereof dispersed therein. The method further includes applying steady direct electric current through the anode, the electrolyte bath and the cathode to coat the article with cobalt, phosphorous and the tribological particles. An improved composition of matter is also provided that may be used as a coating, or the composition may be electroformed on a mandrel to form an article made from the composition of matter.

Electrocomposite coatings for hard chrome replacement

A method for preparing aluminum and aluminum alloys includes the step of simultaneously honing the surface of the aluminum or aluminum alloy in a zincating solution. The honing removes the aluminum oxide layer from the surface of the aluminum or aluminum alloy work piece while the zincating solution deposits a layer of zinc on its surface. The zincate-honing may be followed by electroplating.
