Abstract
A novel alloy is disclosed which is characterized by high resistance to wear and corrosion. The alloy consists essentially of 2 to 25% chromium, 5 to 30% molybdenum, 3 to 15% tungsten, 2 to 8% copper, 2 to 8% boron, and 0.2 to 2% carbon; the balance being incidental impurities and at least 30% of a metal selected from the group consisting of nickel, cobalt and combinations thereof, with the total of molybdenum and tungsten being at least 16%. The alloy is preferably in the form of a powder for thermal spraying, and coating produced thereby generally have an amorphous structure.
