Cylinder is placed in electric furnace and heated, adhesive is taken out after decomposing entirely, obtains Al2O3Ceramic idiosome；Wherein heating-up temperature is not
Easily too high, the too high thermal expansion phenomenon that can occur of temperature produces negatively influencing, preferable temperature 773K to composite.
(3) by ceramic beads, Al2O3Ceramic idiosome and Al- based alloys are arranged in order are placed on opening diameter from the bottom up
Will flow out liquid alloy moment in 0.5~0.8mm experiment tube, during the excessive pressurization of opening diameter, it is too small to improve pair
Pressure value requires and is unable to reach the state of low pressure pressurization.The addition of ceramic beads can effectively prevent that liquid is direct after being pressurizeed
Spray, preferably, a diameter of 1mm of ceramic beads.Al- based alloys are heated to by high frequency heater to be completely melt, from examination
0.2~0.4MPa of Ar gases is added above pipe to liquid alloy surface, liquid alloy is penetrated into Al2O3In ceramic idiosome；Work as liquid
Body alloy stops pressurization after slowly being flowed out from test tube mouth, obtains metal-base composites after cooling.
Preferably, described adhesive is polyethylene glycol (PEG).Because PEG functional group is hydroxyl, idiosome is being made
Carbon dioxide and moisture will be resolved into by heating during shaping, do not have any influence on material.
Preferably, pure Al particle diameters are 18 μm, Al2O3Fibre diameter is 3~10 μm, Al2O3Particle diameter is 20 μm.
Under the size range, it is more evenly distributed between particle, gap is little between particle, and the wearability of sample is optimal.
Preferably, the Al- based alloys are the albronze that Cu contents are 4mass%, aluminium copper on this condition
Age-hardening processing can be done.
Preferably, heater heating-up temperature is 1173K in step (3).

Metal-base composites prepared by son is compared in wearability has advantages below：
1st, the present invention contact by adding pure Al particles and melted with molten state Al- based alloys and increased between strengthening material
Space, pressure required during die casting is reduced, reach the purpose of low pressure pressurization.Have compared with traditional solid phase method, liquid phase method
There is the advantages that low cost, efficiency high.
2nd, the present invention passes through Al2O3Fiber mixes with enhanced particles, solves strengthening material and is easier in liquid alloy
The problems such as even scattered.
3rd, by the present invention in that Al2O3Fiber is presented distributed in three dimensions in the composite, can protect Al during fretting wear2O3
Particle consolidates, and is not easy to be split away off, improves the anti-wear performance of material.
