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 25 atom percent cobalt, 0 to about 20 atom percent iron, 0 to about 15 atom percent chromium, 0 to about 16 atom percent tungsten, 0 to about 5 atom percent molybdenum, about 2 to about 20 atom percent boron, 0 to about 10 atom percent silicon and 0 to about 5 atom percent carbon, the balance being nickel and incidental impurities with the proviso that the total of 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 hardfacing foil permits continuous hardfacing of soft matrix, like low carbon and low alloy steels, and imparts superior resistance to wear and corrosion.
