Description
Technical field
The present invention relates to a kind of graphene aluminum silicon carbide composite materials and preparation method thereof and its application.
Background technique
Aluminium is the second largest metalloid for being only second to steel, with light, intensity is good, ductility is good, electric conductivity is strong, good
The advantages that corrosion stability, is widely used in the industries such as building, packaging, electronics, transport, and aviation, national defence and automobile and other industries are to aluminium
Demand is increasing.
Aluminium silicon carbide is a kind of metal-base composites, and has merged the different advantages of silicon carbide ceramics and metallic aluminium, tool
There are small density, light-weight, high rigidity and high-tensile.But some structural members with particular/special requirement or for special
The structural member of working environment has requirements at the higher level to the performance of aluminium alloy and aluminum silicon carbide composite material.Firstly, to have more excellent
Different mechanical property.Lightweight, high-strength, high specific strength, high elasticity modulus are the targets constantly pursued；Secondly, good resistance to
Fatigue behaviour also can make structural member more competitive in some application fields；Again, structural member should also have designing for performance
Property, need to consider the composite material of different structural requirement design different performances.
Graphene be it is a kind of with high conductivity, high thermal conductivity, high-modulus, high intensity two-dimensional surface nano material,
Excellent mechanical property and physical property makes it have great application prospect.Have and Al/SiC composite material is added in graphene
In to improve the report of material property.Graphene is added in Al/SiC composite material, significantly improves intensity, the plasticity of material
And toughness, improve the subsequent mechanical processing of material, makes material that there is broader practice prospect using upper in structural member.
105924178 A of CN discloses a kind of method that pressure permeation method prepares aluminum silicon carbide composite material, by powder
Filling, in the forming under the pressure of 10Mpa, forms nearly molding biscuit into mold.It will be sintered after mold jacket encapsulation with biscuit,
Biscuit forms prefabricated component.By the mold jacket encapsulation leaching aluminium equipped with prefabricated component, aluminum silicon carbide composite material is made.The system of this method
Paraffin microemulsion is not added in standby raw material, and reduces the amount of aluminium dihydrogen phosphate, and the gap of biscuit is high, and the aluminium body of composite material is made
Fraction is big, improves thermal conductivity, and simplify process route, saves cost, is suitble to large-scale production.But this method exists
Silicon-carbide particle aggregation, reinforced phase is unevenly distributed, there are anisotropy for material, and then it is high-end with performance to influence its.
105801154 A of CN discloses a kind of graphene enhancing aluminum silicon carbide composite material and preparation method thereof, this is compound
Material wraps up one layer of SiO on redox graphene surface using graphite oxide as carbon source, using hydro-thermal method2Particle, so that graphite
Alkene and SiC form good boundary layer, and are uniformly dispersed；Through high temperature sintering, in graphene and SiO2Interface passes through carbon heat also
Original reaction, growth in situ silicon carbide whisker and particle, improve boundary strength and oxidation resistance, generate interface enhancing effect, increase
Add crack growth resistance, further improve ceramic fracture toughness, to overcome stone in graphene/carbon SiClx composite material technology of preparing
Growth in situ, crackle self-healing and strengthening and toughening mechanism of are applied to stone by the defects of black alkene bad dispersibility and poor high-temperature oxidation resistance
In the technology of preparing of black alkene/carbofrax material, and then obtain the excellent graphene toughening carbonization of mechanical performance, interfacial combined function
Silicon ceramics.But this method need to have the defects that reaction process is difficult to control through high temperature sintering and carbothermic reduction reaction.
CN104264000A discloses a kind of powder metallurgic method and prepares graphene enhancing aluminium silicon carbide Electronic Packaging composite wood
The method of material includes the following steps: 1) to impregnate reinforcement particle with strong acid solution, then is cleaned with deionized water to neutrality, goes
Except surface impurity, the reinforcement particle being activated is made in drying；2) the reinforcement particle of activation processing is added to graphene
In dispersion liquid, the modified enhancing of graphene is made in its surface coated graphite alkene nanometer sheet by mechanical stirring or ultrasonic disperse
Body particle；3) the modified reinforcement particle of graphene is mixed with aluminum substrate powder, by green compact and sintering, obtained graphene changes
The high thermal conductivity aluminum matrix composite of property.Composite material surface made from this method has isotropic, gas hole defect rich in gloss
Less, enhancing phase volume fraction is easy to change, is easy to regulate and control the advantages that performance of composite material.But strong acid need to be used, it is hidden to there is safety
Trouble and environmental issue.
CN104848748A discloses a kind of method for preparing graphene aluminum silicon carbide composite material using pressure permeation method,
This method mixes graphene with ethanol solution, evenly dispersed graphene alcohol dispersion liquid is made, then SiC powder is added should
In mixed solution, ball milling is uniformly mixed, and mixture is pressed into skeleton, high temperature molten aluminum is added in a manner of Pressure Infiltration by drying
In skeleton, graphene aluminum silicon carbide composite material is made.This method has forming simple, and it is excellent to be not necessarily to subsequent complicated machinery processing etc.
Point, but be unevenly distributed there are reinforced phase and the problems such as there are gas hole defects, so cause material property there are anisotropy,
Surface is larger, the defects of being unable to control silicon carbide volume additional amount and other reinforced phase (such as graphene) contents.Also, this method
Graphene/carbon SiClx reinforced aluminum matrix composites are prepared by preparing the method for SiC ceramic prefabricated component pressure impregnation, it need to be by aluminium
Liquid is heated to 700~750 DEG C, there is control difficulty and safety issue；And use ball milling method (about 10~20 hours) by stone
Black alkene alcohol dispersion liquid is added in aluminum silicon carbide composite material, there is the defects of mixing is not uniform enough.
