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. The resulting coated tool has exceptional wear resistance and bond strength, especially for ground engaging tools.
