Patent attributes
A method for manufacturing a single-element matrix cobalt-based granular media alloy composition formulated as Cof1-(MuOv)f2, M representing a base metal selected from the group consisting of magnesium (Mg), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), aluminum (Al), silicon (Si), yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo), ruthenium (Ru), indium (In), lanthanum (La), hafnium (Hf), tantalum (Ta), and tungsten (W), u and v representing the number of atoms of base metal M and oxygen (O) per oxide formula, respectively, and f1 and f2 being mole fractions represented by the equation f1+(u+v)f2=1. The method includes the steps of blending a Co-M master alloy powder and a Cou′Ov′ powder into a corresponding (CoaM1−a)f1′-(Cou′Ov′)f2′ formula, and densifying the blended powders.
