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 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.

Abstract: Two metal objects are bonded together by positioning a brazing composite on the surfaces that are to be bonded together and heating the metal objects causing the composite to disintegrate with brazing alloy that is held in the composite melting to bond the two surfaces together. The composite is a combination of the brazing alloy and fibrillater polytetrafluoroethylene. This product which is very malleable can be formed to any desired shape to facilitate bonding a variety of different objects together. It is particularly useful for bonding honeycombed objects to metal surfaces.
Abstract translation: 两个金属物体通过将钎焊复合材料定位在待粘合在一起的表面上并且加热金属物体而将金属物体结合在一起，从而使复合材料与保持在复合材料中的钎焊合金分解以将两个表面粘合在一起。 复合材料是钎焊合金和原纤维聚四氟乙烯的组合。 这种非常有延展性的产品可以形成任何期望的形状，以便于将各种不同的物体粘合在一起。 将蜂窝状物体粘合到金属表面特别有用。

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.

Abstract: A method of cleaning a metal surface includes covering the portion of the metal surface with a cleaning tape. The cleaning tape is chromium in combination with a fluoride ion source bound together by fibrillated polytetrafluoroethylene. This is applied to the portion of the area to be cleaned and is subject to heat treatment at about 1800.degree. F. and a reducing atmosphere of preferably hydrogen. This effectively cleans only the area covered by the tape. Further, the tape and binder format acts to force fluoride ions into the cracks on the surface providing a significantly improved cleaning operation.

Abstract: Corrosion resistant metal, either platinum or MCrAlY is bonded to a corrosion sensitive metal such as nickel based superalloys by coating the surface with the corrosion resistant metal particles held in a binder and covering this with a metalide generating tape. This is then heated to cause the formation of the metalide coating on the metal surface, which in turn, bonds the corrosion resistant metal to the surface.
