Abstract: The present invention relates to a high hardness amorphous composite, a method of preparing the high hardness amorphous composite and application thereof. The high hardness amorphous composite includes a basic alloy component, a hard additive and a bonding additive. The basic alloy component includes 45-60 mole % Zr, 5-10 mole % Hf, 5-15 mole % Al, 8-22 mole % Ni and 6-14 mole % Cu, the hard additive is ZrC or WC nanometer powder with addition amount at 12-26 wt % of the basic alloy component, particle diameter of the WC nanometer powder is 10-100 nm, and the bonding additive is any one or two selected from groups of Re, W or Mo with addition amount at 4-8 wt % of the basic alloy component. The high hardness Zr-based amorphous composite with good workability and formability is provided by improving composition of alloy based on Zr—Al—Ni—Cu, adding new component and adjusting component content.
