Patent ID: 7776451

Claim:
A composite overlay compound and substrate, including: a steel matrix with steel extending substantially throughout the matrix, the matrix including at least one component from a first group of component materials including titanium, chrome, and molybdenum, the matrix also including at least one component from a second group of component materials including silicon, nickel, and manganese; hard-particles distributed substantially uniformly in the matrix, the hard-particles including at least one of carbide and boride synthesized during formation of the matrix, the matrix and the hard-particles cooperatively defining the composite overlay compound, wherein the composition of the composite overlay compound includes 5 to 50 wt % of the first group of component materials and 0.2 to 20 wt % of the second group of component materials; and a substrate disposed below the composite overlay compound, the matrix being fused to the substrate material with a metallurgical bond.
