Adhesion of Rubber to Brass Plate

The brass-plating process is one of the most important methods of bonding rubber to metal. It consists of depositing a thin layer of copper zinc alloy on the surface of the metal. The rubber is then moulded in contact with the brass deposit, and in most cases, a strong bond is established during vulcanization. Even, however, when all precautions are taken, bond failures occur, often with no obvious cause, so the process is still somewhat suspect. It is only fair to say, however, that this variability appears to be common to most methods of bonding rubber to metal, and that in general production a high level of adhesion is maintained.
