ABSTRACT:
A braze paste is disclosed for brazing superalloys together which includes an organic binding system, a major amount of a nickel, cobalt, gold, silver, copper or palladium based braze alloy and ground polytetrafluoroethylene. The braze paste can be used to braze superalloys together without prior nickel treatment. In the brazing step, the polytetrafluoroethylene decomposes and forms fluoride ions which in turn acts on any oxide that may form during the brazing step to remove the oxide and permit a good braze between the metal objects.
