Hard facing nickel-base alloy
Abstract
Abstract PCT No. PCT/JP79/00026 Sec. 371 Date Oct. 24, 1979 Sec. 102(e) Date Oct. 24, 1979 PCT Filed Feb. 5, 1979 PCT Pub. No. WO79/00772 PCT Pub. Date Oct. 4, 1979.Hard facing nickel-base alloys comprising 0.05 to 1.5% by weight of boron, 3 to 7% by weight of silicon, 7.5 to 35% by weight of chromium, 0.05 to 1.5% by weight of carbon, and if necessary, less than 30% by weight of iron and/or less than 5% by weight of tungsten, the balance being nickel, with the weight ratio of silicon to boron being equivalent to or exceeding 3.3. The alloys have a high degree of toughness, ductility, wear resistance and corrosion resistance, and no cracks occur in the hard facing layer. Addition of 0.1 to 3% by weight of the tin and/or 0.1 to 3% by weight of tantalum remarkably increases the corrosion resistance. The alloys can be used as a hard facing material to be applied to parts of various instruments, machines and plants.
