  • Soldering composition
    Patent number: 4342606
    Abstract: This invention relates to joining metallic parts by soldering and in particular to a soldering composition.A soldering composition in accordance with the present invention is solid at ambient temperatures and comprises a particulate soldering alloy or metal or oxide precursor thereof dispersed in a thermoplastic material. Conveniently, the soldering composition also includes one or more fluxes.

  • Removal of surface material
    Patent number: 4246083
    Abstract: The removal of a metal or alloy from the surface of a body, in particular turbine blades, by forming close to as in contact with the surface a one or more other metal or metals which will alloy with the metal or alloy to be removed. By forming the one or more other metals in situ, for example by electrolytic methods, attack of the underlying surface such as occurs when removal is effected by dipping the body in a bath of molten metal, is avoided.

  • Alloys of titanium
    Patent number: 4139373
    Abstract: This invention relates to titanium alloys consisting, apart from impurities, of 60 to 94 weight % titanium and 6 to 40 weight % of at least one additional metal selected from the group consisting of iridium, rhodium, ruthenium, platinum and palladium. Alloys according to this invention possess corrosion rates lower than those of titanium metal alone and they are eminently suitable for carrying electric current.
