Abstract
A brass coated metallic wire for use as a reinforcing component in an elastomeric article, such as a motor vehicle tire. The brass coating is formed by depositing alternate layers of copper and zinc on the wire and then drawing the wire under conditions of temperature and pressure suitable to alloy the copper and zinc to form a brass coating on the wire.
Claims6
A wire reinforced article of an elastomeric composition, said article containing at least one drawn metal wire having a copper-based alloy coating, said copper-based alloy coating having an outer surface and an inner surface, wherein a copper content of said outer surface is greater than a copper content of an inner portion of said copper-based alloy coating.
A wire reinforced article of an elastomeric composition, said-article containing at least one drawn metal wire having a copper-based alloy coating, wherein the at least one drawn metal wire is formed by depositing at least three alternate unalloyed layers each unalloyed layer comprising copper or zinc with a most external of the unalloyed layers being copper.
A wire reinforced article of an elastomeric composition, said article containing at least one drawn metal wire having a copper-based alloy coating, wherein said copper-based alloy coating comprises at least three alternate unalloyed layers, each unalloyed layer comprising copper or zinc with a most external of the unalloyed layers comprising copper and drawing the wire to alloy the unalloyed layers such that a copper content of an outer surface of the coating is greater than a copper content of an inner portion of the coating.
