Abstract
A base metal repair tape includes a first layer formed braze alloy bonded together with fibrillated polytetrafluoroethylene, a second layer formed from powdered base metal comprising oxygen-sensitive superalloy bonded together by fibrillated polytetrafluoroethylene and a third layer comprising a brazing alloy bonded together by fibrillated polytetrafluoroethylene. This is used to repair base metal by placing the first layer on the base metal and brazing the base metal powder so that the brazing alloy melts and diffuses into the base metal powder bonding it to the surface of the article. This permits the braze powder to be bonded to the base metal surface with minimal distance between the base powder particles. The number of alternating layers of base metal and braze alloy can be increased to increase the thickness of the repair. This can also be used to form small intricate parts.
