Method to improve adhesion between pre-cured elastomer and metal surface

摘要

The bond strength between a pre-cured elastomeric member and a metal surface is increased by applying a phosphate coating to the metal surface. This is particularly suitable for use in formation of torsional vibration dampeners wherein an elastomeric member is compression fitted between an outer annular ring and a hub thereby decreasing slippage between the annular weight and the hub.
