  • Process for hard facing a metallic substrate to improve wear resistance
    Patent number: 6156391
    Abstract: A method for hard facing a tool. The method is carried out by thermally spraying the tool with a composition which includes between 11/2%-10% carbon, 0-3% fluorides, 11/2-5% boron, 20-40% chromium, 1-15% nickel and the remainder iron.
