ABSTRACT HOMOGENEOUS, DUCTILE IRON BASED HARDFACING FOILS Hardfacing of metal parts employing a thin, homogeneous ductile foil is disclosed. The hardfacing foil has a composition consisting essentially of about 0 to about 25 atom percent cobalt, 0 to about 30 atom percent nickel, 0 to about 30 atom percent chromium, 0 to about 5 atom percent tungsten, 0 to about 4 atom percent molybdenum, about 2 to about 25 atom percent boron, 0 to about 15 atom percent silicon, and 0 to about 5 atom percent carbon, the balance being iron 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 foil permits continuous hardfacing of soft matrix, like low carbon and low alloy steels, imparting superior resistance to wear and corrosion.
