Abstract
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 weigh and the hub.
Claims (4)
1. A vibration dampener comprising a metal weight, a pre-cured elastomeric member and a metal hub adapted to attach to an automotive engine wherein said metal weight and said metal hub have a phosphate-coated surface and wherein said elastomeric member is compression fitted between said metal weight and said metal hub contacting said phosphate-coated metal surfaces wherein said elastomeric member is selected from the group consisting of ethylene propylene diene monomer rubber and ethylene acrylate copolymer.
2. The vibration dampener claimed in claim 1 wherein said weight is an annular ring and wherein said phosphate coated surface is an inner annular surface of said annular ring and said phosphate coated surface of said metal hub is an outer annular surface of said hub.
3. The vibration dampener claimed in claim 2 wherein said elastomeric member is an ethylene acrylate.
4. The dampener claimed in claim 2 wherein said elastomeric member is EPDM.
