High hardness amorphous composites and their manufacturing methods and applications

摘要

The present invention relates to high hardness amorphous composites, methods of making high hardness amorphous composites and their uses. High hardness amorphous composites include base alloy components, hard additives and binding additives. The base alloy component comprises 45-60 mol% Zr, 5-10 mol% Hf, 5-15 mol% Al, 8-22 mol% Ni and 6-14 mol% Cu, The WC nanometer powder has a particle diameter of 10-100 nm and the binding additive is Re, W or Mo having an addition amount of 4-8% by weight of the base alloy component, / RTI The high-hardness Zr-based amorphous composites have excellent processability and moldability by improving the composition of the Zr-Al-Ni-Cu alloy, adding new components, and adjusting the component content.
