  • Method of forming corrosion resistant coating
    Patent number: 4529616
    Abstract: An improved thermal spray nickel base alloy powder which forms an extremely tenacious, dense corrosion resistant coating on metal parts subject to a corrosive environment. The disclosed thermal spray powder is a nickel base alloy having 20 to 40% by weight molybdenum, and 12 to 20% by weight chromium, and preferably includes 0 to 10% by weight iron and 0.03 to 2% by weight copper plus vanadium. The metal alloy powder is preferably formed by atomizing the molten alloy, and the coating is preferably formed by thermal or plasma spray.
