ABSTRACT:
A base metal repair tape includes a first layer formed from powdered base metal bonded together by fibrillated polytetrafluoroethylene and a second 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 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.
