Patent ID: 7615124

Claim:
A process for manufacturing plated-steel wire in which a plating coating is intimately bonded by high pressure to a steel core, the method comprising selecting steel for the core having relatively moderate mechanical properties with a strength R m of between 800 and 900 MPa and being a hardenable steel, applying a plating metal coating to the core, wherein the plating metal is chosen from the group consisting of titanium and titanium alloys, stainless steel, nickel and nickel alloys, and selecting the materials of the core and of the coating so that the difference between their respective mechanical strength R m properties is not greater than 200 MPa; and intimately bonding the coating to the core forming a plated wire and applying a rapid high-temperature hardening step to the plated wire, which is accompanied by a controlled martensitic transformation, and then applying a tempering step to the wire.
