Method for manufacturing composite material of metal/ceramic layer structure
The invention discloses a method for manufacturing a composite material of a metal/ceramic layer structure. The method for manufacturing the composite material of the metal/ceramic layer structure adopts the following technologies: 1, bonding alloy preparation: the bonding alloy is Al-Zn-Fe-Ti alloy and comprises the following components in percentage by mass: 5%-40% of Zn, 0.5%-10% of Fe, 2%-20% of Ti, and the balance is Al; the bonding alloy is composed of a high melting point phase and a low melting point phase, is in solid phase under the normal temperature and is in solid-liquid phases with solid phase being 60%-80% and liquid phase being 40%-20%; and the melting point of the bonding alloy, the interface reaction phase and the phase composition can be adjusted by utilizing the contents of added composition elements of Zn, Ti and Fe; and 2, composite material preparation: heating ceramic and metal to a processing temperature simultaneously, then making the bonding alloy carry out a recombination reaction with the ceramic and the metal, making the ceramic and the metal be in composite molding together under the condition that the temperature is 80-120 DEG C higher than the melting point of the high melting point phase of the bonding alloy, and the composite material of the metal/ceramic structure can be formed by demoulding.
