Abstract: PROBLEM TO BE SOLVED: To easily and cost effectively improve the adhesiveness to a vulcanized elastomer material, corrosion resistance and compressing and expanding property efficiently by coating metallic structural parts of steel wire or the like with a layer of an alloy having a specified compsn. of ZnMoX (X denotes Co, Fe and Ni) by electrodeposition. SOLUTION: The surface of steel wire as strengthening structural parts for a product of a vulcanized esastomer material is coated with a layer of an alloy ZnMoX composed of, by weight, 0.05 to 3%, preferably 0.1 to 1% Mo, 95 to 99.9%, preferably 98 to 99.5% Zn and 0.05 to 2%, preferably 0.1 to 1% metal X. This surface-coated layer is formed by passing steel wire through the inside of an electrolytic bath composed of an aq. soln. contg. the salt of each alloy element at a rate of 10 to 70 m/in, preferably 20 to 50 m/min and executing electrodeposition at 20 to 50 deg.C, 2 to 6 pH and 10 to 50 A/dm2 cathode density. The thickness of the coating layer is preferably controlled to about 1 to 4 μ before compressing and expanding for the steel wire and to about 0.1 to 0.4 μ after the compressing and expanding.

Abstract: PROBLEM TO BE SOLVED: To obtain a coated metal wire suitable for reinforcing material for wire reinforced rubber products by forming metal layer free from alloy alternately laminating cupper and zinc on the surface of metal wire, and then drawing to form an alloy. SOLUTION: The metal coated wire is obtained by electrodepositing 0.75 to 4.0 μm of non alloy layer by alternately laminating cupper and zinc comprising at least three layers to form the layers having 0.1 to 0.5 of cupper external layer on the metal wire, for example cupper wire, having diameter 0.85 to 3.0 mm installing a corrosion resistant layer comprising tin. The metal wire having non-alloy layer is drawn to obtain alloy coated metal wire coated with the alloy essentially comprising 2 to 13 wt.%. of tin, 23 to 34% of zinc and 59 to 73% of cupper.

Abstract: A method for producing a metal wire for reinforcing an elastomeric material as well as a metal wire and a metal cord for reinforcing such an elastomeric material are described. The metal wire comprises a metal core having a predetermined initial diameter and a metal coating layer. The method comprises the steps of: a) submitting the core to at least one surface treatment for predisposing the surface of the core to being coated with the coating layer; b) thermally treating the core; c) depositing the metal coating layer to a predetermined initial thickness on the core by means of a plasma deposition technique; and d) drawing the coated core until the core has a final diameter smaller than said predetermined initial diameter and the metal coating layer has a final thickness smaller than said predetermined initial thickness. Advantageously, it is possible to obtain a wire coated in a uniform and homogeneous manner, including a core having a smooth surface suitable for the deposition of the coating layer and a structure suitable for the cold deformation involved in the drawing step.
