Description
Technical field
The present invention relates to technical field of composite materials, and in particular to a kind of ceramic-metal composite.
Background technology
The composite that ceramic-metal composite is made up of one or more ceramic phases and metal phase or alloy.Gold
Ceramic phase in category ceramics is oxide or infusible compound with high-melting-point, high rigidity, and metal phase is mainly transition elements
(iron, cobalt, nickel, chromium, tungsten, molybdenum etc.) and its alloy.Different according to each composition phase percentage, cermet is divided into and is with ceramics
Matrix and with metal be the class of matrix two.Ceramic based ceramic metal mainly has following a few classes：1. oxide base cermet, to aoxidize
Aluminium, zirconium oxide, magnesia, beryllium oxide etc. are matrix, are composited with tungsten, chromium or cobalt, rotten with high temperature resistant, anti-chemistry
The features such as erosion, good thermal conductivity, high mechanical strength, can be used as the crucible and metal cutting tool of guided missile nozzle insert, smelting metal.
2. carbide-base ceramics.With titanium carbide, carborundum, tungsten carbide etc. as matrix, with the metal such as metallic cobalt, nickel, chromium, tungsten, molybdenum
It is composited, the features such as with high rigidity, high-wearing feature, high temperature resistant, for manufacturing cutting tool, high-temperature bearing, sealing ring, picking up
Silk die sleeve and turbine blade.3. nitride based ceramic metal.With titanium nitride, boron nitride, silicon nitride and tantalum nitride as matrix, have
Superhard, shaking property of heat resistanceheat resistant and good high temperature creep, using less.It is excellent with ceramics that ceramic-metal composite has metal concurrently
Point, its density is small, hardness is high, wear-resisting, thermal conductivity is good, will not be because of quenching or shock heating and embrittlement.Cermet both has metal
Toughness, high-termal conductivity and good heat endurance, and the characteristic such as the high temperature resistant with ceramics, corrosion-resistant and wear-resistant.Therefore,
Ceramic-metal composite can be widely used in the ground such as rocket, guided missile, the shell of supersonic plane, the flame jet of combustion chamber
Side.But there is the demand of anti-rapid heat cycle and resistance to high temperature oxidation to material to some field hot-extrusion molds, therefore need to be to existing gold
Category ceramic material constituent carries out reasonable disposition.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of ceramic-metal composite, with good thermally-stabilised
Property, red hardness and excellent wearability high meet material but also with excellent anti-rapid heat cycle and resistance to high temperature oxidation.
To realize object above, the present invention is achieved by the following technical programs：A kind of ceramic-metal composite, respectively
The weight portion of component is：Alundum (Al2O3) 40-50 parts, aluminium powder 20-30 parts, copper powder 15-25 parts, titanium carbide 10-20 parts, tungsten 10-
20 parts, iron 10-20 parts.40 parts of the alundum (Al2O3), 20 parts of aluminium powder, 15 parts of copper powder, 10 parts of titanium carbide, 10 parts of tungsten, 10 parts of iron.
50 parts of the alundum (Al2O3), 30 parts of aluminium powder, 25 parts of copper powder, 20 parts of titanium carbide, 20 parts of tungsten, 20 parts of iron.The alundum (Al2O3)
45 parts, 25 parts of aluminium powder, 20 parts of copper powder, 15 parts of titanium carbide, 15 parts of tungsten, 15 parts of iron.The preparation method of ceramic-metal composite, first
After by above-mentioned component material ball milling, it is fitted into graphite jig, is sintered 30-40 minutes at a temperature of 1200 DEG C -1600 DEG C.
Beneficial effect of the present invention：The present invention carries out reasonable disposition to raw material, through oversintering after being combined by one, prepares into
This is low, with good heat endurance, red hardness and excellent wearability high, but also with excellent anti-rapid heat cycle and anti-height
What temperature was aoxidized meets material.
