摘要 |
The invention concerns a metal wire, used to produce reinforcing elements for articles of elastomeric material, which is provided with a coating able to ensure at the same time a good resistance to corrosion, good values of initial adhesion and a low decay, due to ageing, of the bond with the elastomeric material, said coating being formed by two concentric layers of a Zn/Ni alloy, where the radially inner layer contains Zn in an amount ranging between 60% and 90% on the layer total and the radially outer layer contains Ni in an amount ranging between 60% and 80% on the layer total. |
