    Abstract: The process for manufacturing a steel wire comprises: providing a steel wire; austenitizing said steel wire; patenting said steel wire; drawing said steel wire. The patenting of said steel wire comprises: slow cooling said steel wire to a first predetermined temperature; quick cooling the steel wire to a second predetermined temperature; keeping said steel wire at said second predetermined temperature. During the slow cooling, the steel wire substantially keeps its austenite structure unaltered; with the subsequent quick cooling, the steel wire is taken to the best conditions in order to start the phase change in which the austenite structure is transformed into a pearlite structure.

    Abstract: The present invention relates to a method and an apparatus for producing a steel wire for reinforcing an elastomeric material. The steel wire comprises a metal core (5) and a coating layer made of a metal alloy material having a composition including at least one first metal component and at least one second metal component. According to the invention, the method comprises the steps of: a) conveying the steel core (5) along a predetermined path in a substantially continuous manner; b) co-sputtering at least one first powered cathode (1; 1',1') made of said first metal component and at least one second powered cathode (2; 2',2') made of said second metal component onto the steel core being moved along said predetermined path to obtain a coating layer made of a metal alloy material of a first composition; and c) adjusting the power provided to at least one of said first (1; 1',1') and second cathode (2; 2',2') to obtain a coating layer made of a metal alloy material of a second composition.
