Zusammenfassung:	D. E. Koontz 11 TECHNIQUE FOR STABLIZING CONTACT RESISTANCE OF GOLD PLATED ELECTRICAL CONTACTS A technique is described for stablizing gold plated electrical contacts wherein the contacts are treated with an oxidizing agent at elevated temperatures, so resulting in a contact structure which does not evidence resistance drift during subsequent thermal aging. Additionally, the technique may be used to reduce the contact resistance of thermally aged contacts which were not subjected to the foregoing preparative process. -i-
