<p>A novel alloy is disclosed which is characterized by high resistance to wear and corrosion. The alloy consists essentially of up to 25% chromium, 10 to 28% molybdenum, 0.5 to 18% tungsten, 0.1 to 10% copper, 2 to 8% boron, 2.5 to 8% silicon, and up to 3% carbon; the balance being incidental impurities and at least 30% of a metal selected from the group consisting of nickel, cobalt and combinations thereof, wherein the total of boron and carbon is at least 2.5%. The alloy is preferably in the form of a powder for thermal spraying, and coatings produced thereby may be subsequently fused.</p> |
