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&#x2014;Al&#x2014;Ni&#x2014;Cu, adding new component and adjusting component content.

High hardness amorphous composite and preparation method and application thereof

A casting and molding equipment for producing an amorphous alloy structural unit, including an injection system, an alloy melting system, a material feeding system, a mold system, a vacuum system, and a protective gas supply system. The injection system includes an injection tube, an injection mechanism, and a plunger rod; the plunger rod is adapted to move along an inner wall of the injection tube, and the injection mechanism is configured to control a moving direction and moving speed of the plunger rod. The alloy melting system includes a melting chamber and a heating unit; the heating unit is configured to melt an alloy material in the melting chamber; the heating unit includes an induction coil or resistance wire; the melting chamber is disposed in the injection tube, and the heating unit is disposed out of the injection tube.
