A method for the manufacture of bearing metal liners, such as those suitable for connecting rod and main bearings. which comprises the electrodeposition of a composite electroplate of one or more of the metals of the group consisting of copper, nickel, cobalt, iron or their alloys containing densely codeposited fine non-metallic insulator particles, followed by a thin electroplate of copper, silver, nickel, cobalt, iron or their alloys that will have dense vertical porosity by virtue of having been deposited on the metallic surface containing the densely codeposited non-metallic insulator particles. The highly porous plate is then overlaid with a final lead-tin alloy electrodeposit, which by plating into the dense porosity of the underlying metal, produces in effect a copper-lead; a nickel-lead; a cobalt-lead; a silver-lead; or the like "alloy" plate with an overlayer of lead alloy plate. |
