  • Patent number: 4801072
    Abstract: Metal parts are brazed by means of an amorphous filler metal foil. The brazing foil, useful for brazing stainless steels, has a composition consisting essentially of about 0-10 atom percent iron, about 0-20 atom percent chromium, about 3-5 atom percent molybdenum, about 5-35 atom percent cobalt, about 14-19 atom percent boron and the balance nickel and incidental impurities. The ductile foil permits fabrication of preforms of complex shapes which do not require binders and/or fluxes necessary for brazing powders presently used to braze stainless steels and nickel base alloys, and exhibits excellent braze-metal and high-temperature strengths.

  • Patent number: 4701357
    Abstract: Hardfacing of metal parts employing a thin, homogeneous, ductile foil is disclosed. The hardfacing foil has a composition consisting essentially of 0 to about 32 atom percent nickel, 0 to about 10 atom percent iron, 0 to about 30 atom percent chromium, 0 to about 2 atom percent tungsten, 0 to about 4 atom percent molybdenum, about 5 to about 25 atom percent boron, 0 to about 15 atom percent silicon and 0 to about 2 atom percent manganese and 0 to 5 atom percent carbon the balance being cobalt and incidental impurities with the proviso that the total or iron, cobalt, nickel, chromium, tungsten and molybdenum ranges from about 70 to 88 atom percent and the total of boron, silicon and carbon ranges from about 12 to 30 atom percent. The ductile foil permits continuous hardfacing of soft matrix, like low carbon and low alloy steels, imparting superior resistance to wear and corrosion.
