Document Type and Number:
WIPO Patent Application WO/2002/066732
Kind Code:
A1
Abstract:
A steel wire and a steel cord used as reinforcing materials for rubber articles such as pneumatic tires and industrial belts, particularly, those having an excellent adhesiveness to rubber, wherein the amount of phosphorous contained as an oxide is suppressed to 1.5 atomic % or less in a surface layer area ranging from the surface of a brass plating applied onto the peripheral surface of the wire to a depth of 5 nm in inner radial direction of the wire, whereby an excellent adhesiveness can be provided between the steel cord and a coated rubber even if an adhesion accelerator added to the coated rubber composition of the steel cord is reduced or absent.
