A kind of metal ceramic composite plate and preparation method thereof, pass through ceramic skeleton and alloy solution integrated formed structure, ceramic skeleton and alloy can be made to become an entirety, avoiding the two separation influences its service life, the two is closely linked simultaneously, and wherein the volume shared by ceramics is more than volume shared by alloy, it can reduce so all using high cost caused by ceramal, it improves simultaneously all using the problem of the deficiency of wearability caused by alloy, this structure substantially increases wearability under the premise of guaranteeing cost input.
Description
Technical field
The present invention relates to composite ceramics fields, more particularly, to a kind of metal ceramic composite plate and preparation method thereof.
Background technique
Ceramal has the advanced composite material (ACM) of the high temperature resistant of ceramics, the ductility of corrosion resistance and metal, toughness concurrently.
What a kind of ceramal that foreign countries succeed in developing was made of silicon carbide silk, the gap of silicon carbide silk is also filled with
Silicon so that this material be made to have certain toughness and the curved characteristic of energy, and can have at high temperature as metal and prolong
Malleability.This composite material of silicon carbide can pour into various parts, these components hardly happen receipts in condensation process
Contracting, therefore the expensive for paying general Ceramic manufacturing can not be needed with one-pass molding.
However ceramal cost or excessively high is directlyed adopt, especially in wear-resistant liner use process, due to wear-resisting
Liner plate is a kind of consumables, and higher extruding force and shearing force are born in surface.Currently, common wear-resistant liner generally uses double gold
Belong to heap welding plate, rubber ceramic clad plate or ceramic welding liner plate, it the defects of there are grooves on the surface of bimetallic heap welding plate, can be tight
Ghost image rings service life, and rubber is easy aging in rubber ceramic clad plate, such that ceramics fall off and influence service life,
The unbearable large impact of ceramic welding liner plate, and influenced to be easy failure by high temperature.
Summary of the invention
The purpose of the present invention is short to solve service life caused by after ceramic wafer and metal plate combine in the prior art
Problem provides a kind of metal ceramic composite plate and preparation method thereof.
The deficiency of the present invention to solve above-mentioned technical problem, used technical solution is:
A kind of metal ceramic composite plate, the metal plate including rectangular-shape open up in the upper and lower surface of cuboid metal plate

The second through-hole of cuboid metal plate is worn, z row's y column are offered in the front and rear surfaces of cuboid metal plate runs through cuboid metal
The third through-hole of plate, x, y and z are natural number, that is to say, that in x, y, z can on only one surface the case where aperture,
It is interconnected between first through hole, the second through-hole and third through-hole, first through hole, the second through-hole and third through-hole have been implanted into pottery
Porcelain core rod, the ceramic core rod in first through hole, the second through-hole and third through-hole form ceramic skeleton, ceramic skeleton in integral structure
Total volume be 1.5-2 times of volume shared by metal in metal plate, generally using is 1.5 times.
A method of metal ceramic composite plate is prepared, is included the following steps:
Step 1: taking volume no more than the sponge plate of the cuboid of metal plate, successively in the upper following table of cuboid sponge plate
Face processes x row y column first through hole, the left and right surface processing x of cuboid sponge plate arranges the second through-hole of z column, cuboid sponge plate
Z is processed in front and rear surfaces and arranges y column third through-hole, and total volume shared by first through hole, the second through-hole and third through-hole is sponge plate
1.5-2 times of middle residue sponge total volume, sponge plate is put into a closed case, mold is made, one is offered on cabinet
With the injected hole that any one hole is connected in first through hole, the second through-hole and third through-hole；
Step 2: taking each ingredient of wear-resistant ceramic in parts by weight, by each ingredient taken after crusher crushes, add
Enter ball mill and carry out ground and mixed, the grain diameter after grinding is not less than 1000 mesh, takes weight for wear-resistant ceramic weight after grinding
The PVP bonding agent and the wear-resistant ceramic powder after grinding of 1%-5% is mixed, and slurry is made；
Step 3: taking mixed slurry in step 2 to be added in the mold prepared in step 1 by injected hole, by mould
Tool is placed in that ventilation is dry until slurry and cavernous body solidification are integrated, and ceramic batch is made；
Step 4: the ceramic batch after solidifying in step 3 is taken to be put into sintering furnace, adjustment sintering furnace temperature is 300-500
DEG C, control sintering time 2h；Sintering temperature is adjusted after 2h to 1600-1700 DEG C, continues sintering time after 2-3 days, it is cooling to take out
Ceramic skeleton is prepared；
Step 5: the ceramic skeleton prepared in the alloy raw material and step 4 of the amount of taking fully, alloy raw material addition vacuum is melted
Melting is carried out in the melting kettle of furnace, and ceramic skeleton is put into progress preheating insulation setting in the die box of vacuum melting furnace
1000-1200 DEG C of temperature, the alloy after melting in smelting furnace is kept the temperature, is then betted in 1000-1200 DEG C of vacuum environment
Enter to make in mold alloy solution to surround ceramic skeleton and form ingot, and ingot is kept the temperature in the environment of 600-800 DEG C
8-12h, then metal ceramic composite plate is prepared in air-cooled rear take out.
The beneficial effects of the present invention are: can be made in the present invention by ceramic skeleton and alloy solution integrated formed structure
Ceramic skeleton and alloy become an entirety, and avoiding the two separation influences its service life, while the two is combined closely one
It rises, and wherein the volume shared by ceramics can all be caused using ceramal more than volume shared by alloy reducing in this way
High cost, while improving all using the problem of the deficiency of wearability caused by alloy, this structure is guaranteeing cost input
Under the premise of substantially increase wearability.
Mold is made by using the method for sponge in the preparation method used in the application simultaneously, the burning point of sponge is
It 280 DEG C, after the completion of blank preparation, is put into sintering furnace and adjusts 300-500 DEG C of temperature, on the one hand blank can be made substantially hard
Change, on the other hand the inside sponge can be burnt away from ceramics, to then be carried out again the problem of reducing disassembly mold
1600-1700 DEG C, sponge can be fully clear from while ceramics are sufficiently hardened, then alloy molten solution and ceramics exist together
Die for molding enhances the associativity of the two so that the two becomes one structure, to avoid the two from being detached from, to extend
Service life.
In use, since the preparation method in the present invention is using integrated molding, traditional liner plate is changed
The case where the two separation of middle appearance, while use can be split to the product in the application using ceramic cutter.
