Method to improve adhesion between pre-cured elastomer and metal surface.U.S. patent: 7,000,745 Issued: February 21, 2006 Inventors: Bruce Christenson and Gary Veselica Assigned as·sign tr.v. as·signed, as·sign·ing, as·signs 1. To set apart for a particular purpose; designate: assigned a day for the inspection. 2. : Eagle-Picher Industries Key statement: The bond strength between a pre-cured elastomeric member and a metal surface is increased by applying a phosphate phosphate, salt or ester of phosphoric acid, H3PO4. Because phosphoric acid is tribasic (having three replaceable hydrogen atoms), it forms monophosphate, diphosphate, and triphosphate salts in which one, two, or three of the hydrogens of the coating to the metal surface. This is particularly suitable for use in formation of torsional vibration Torsional vibration is angular vibration of an object--commonly a shaft along its axis of rotation. Torsional vibration is often a concern in power transmission systems using rotating shafts or couplings where it can cause failures if not controlled. dampeners.
