Difference, under higher shock loading operating condition, composite material is easy to fall off and is broken, to fail.In addition, common uniform pottery
Porcelain enhances metal-base composites normal pressure infiltration difficulty, and osmotic effect is poor, is difficult the performance having had.
CN101899585A burns carbide ceramic particles or hard alloy crushed particles and metal mixed at high temperature
Form column, strip, bulk, honeycomb precast body, it is regularly arranged in casting mold end face, then gold is injected in the gap of ceramic particle
Belong to liquid, forms composite material.Although the impact resistance of composite material can be improved.It can only having infiltration energy with molten metal
The carbide or hard alloy particle of power, cost are still very high.In addition, the process of casting is that each precast body is placed on sand mold
In the middle, complicated for operation, and spatiality is not strong, during pouring metal melt, is also easy to cause the offset of precast body.
It is mutual that CN107056257A prepares three-dimensional network with homemade manipulator and multi-hole drill in the material of the low melting points such as paraffin, plastics
Wear 60oHole, then inside pour into ceramic slurry, with being solidified, drying, being sintered after gel method molding, obtain three
Tie up network interpenetrating 60oThe ceramic skeleton mutually handed over.Although ceramic skeleton interpenetrating is 60oFor stable, firm stereochemical structure, still
Ceramics bracket molding is too complicated, is unable to industrialized production.CN104874768A is first to print the modern designs of plastics using 3D printing technique
The ceramic slurry prepared, is then circulated into plastic pattern by type again, is then placed on burn off plastics in heating furnace, finally uses
The method of extrusion casint obtains three-dimensional spatial compounding material.Although shaping speed is fast, have very during burn off plastics
Big pollution problem does not meet the requirement of environmental protection.CN101912957A is the ceramic bone that SiC ceramic particle is made into network interpenetrating
Frame, then casting metal obtains composite material.When preparing ceramic skeleton, the intersection of ceramic skeleton is easy to make the method
It is concentrated at stress, ceramic skeleton is easy to be broken from the stress raiser of skeleton.

Principle: theory of the invention is to be classified the compound thought of configuration, is on the one hand improved composite material obdurability,
On the other hand also promote the infiltration of molten steel.Because between coarse between the millimetre-sized spherical preformed particles of level-one (ceramic bead)
Gap provides roomy channel for molten steel infiltration, easily infiltrates into, then molten steel is further infiltrated into level-one spherical prefabricated
Intragranular portion (its internal structure with common reinforced phase be uniformly distributed precast body identical).That is, classification configuration is by molten steel to whole
The infiltration problem of a prefabricated body thickness is converted into the infiltration problem inside the spherical preformed particles of millimetre-sized level-one, thus greatly
The difficulty of infiltration is reduced greatly.By this whole effect, making composite material not only has high intensity, and there are also good plasticity
Toughness.It can be used in high impact loads working environment.
Beneficial effects of the present invention:

2, in the case where solving normal pressure infiltration, molten metal is impregnated into the problem of ceramic particle difficulty.The present invention is infiltrated in normal pressure
In the case where, the channel between ceramic bead can be such that molten metal is penetrated into ceramics well, further in ceramic bead
The infiltration in portion is also easy to.Meanwhile the big channel between the bead of metal can not only be easier infiltration metal, it can also be effective
The extension for preventing crackle improves the service life of composite material；
3, using the model of ball-type ceramic bead, without sharp angle effect, crackle is not easy to extend；
4, using the preparation method of ceramic particle reinforced metal base body space lattice composite material, high impact loads can be applied to
Abrasion operating condition under, technics comparing is simple, be suitble to industrial production.
