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 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.
