Abstract: Preforms for use in base metal repair are formed by thermally spraying preferably a blend of a braze alloy and a high temperature alloy onto a separation sheet thereby forming a preform sheet. The separation sheet is removed from the preform sheet and the preform sheet is cut to form individual preforms which can be brazed directly onto a worn area of a high temperature alloy part such as a jet engine part.

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: A highly drill-resistant element, suitable for inclusion into the walls and/or doors of a security container to resist drilling to access the contents of the container is formed by welding onto a steel plate formed of REPUBLIC 100-AR (TM) steel a layer of Tube BORIUM.RTM. material by a known tungsten-inert-gas (TIG welding process). The REPUBLIC 100-AR (TM) steel has a chemical composition and is manufactured to inherently possess a very high yield strength and abrasion resistance. The Tube BORIUM.RTM. material, welded by the thick process, provides a very hard and drill-resistant layer comprising a heterogenous suspension of tungsten carbide particles of selected size in a steel matrix.

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.
