A wire, generally made of steel and used to make composite elements of elastomeric material, is submitted to an electrodeposition process in an electrolytic bath for being coated with a zinc/cobalt alloy in which the average cobalt content is lower than 1%. In the coating thickness made of the zinc/cobalt alloy, different cobalt concentrations exist, that is a 1% to 3% concentration at the area close to the metal and a concentration as low as 0.5% maximum at the overlying area. Adhesion promoters for example consisting of cobalt neodecanate, added to the elastomeric material, promote the adhesion of said elastomeric material to the wire.
