Patent ID: 7442261

Claim:
A method for producing a high wear resistance alloy comprising the steps of: melting an existing known base white cast iron alloy having a known composition and a certain iron and carbon content; adding carbon to the base white cast iron melt in the form of pieces comprising tungsten carbide for complete dissolution by diffusion and thereby increasing the carbon content of the base alloy melt, the tungsten carbide providing a known content relation between tungsten and carbon; adding chromium to said base alloy in an amount sufficient for controlling the solubility of tungsten carbide in the base alloy melt and for providing material for carbide formation; and casting the resulting alloy melt and thereby forming a final alloy with an additional precipitated carbide structure comprising chromium and the carbon added in the form of tungsten carbide, wherein tungsten is substitutionally dissolved in the lattice structure of said chromium carbide structure.
