Description
Technical Field
The invention relates to the technical field of material preparation devices, in particular to a device for preparing a nano reinforced aluminum-based composite material.
Background
The particle reinforced aluminum-based composite material takes aluminum alloy as a matrix alloy, exerts the advantages of small density, good plasticity and strong deformability, takes ceramic particles as a reinforcement and exerts the advantages of good elastic modulus, small thermal expansion coefficient and good wear resistance, thereby forming a new material system. The new material system has not only good strength, rigidity and wear resistance, but also a series of advantages of high thermal conductivity, low expansion coefficient and the like, so that the composite material is widely applied to the fields of aviation, aerospace, transportation, nuclear industry, weapon industry and the like.
The reinforcing phase in particle-reinforced aluminum matrix composites is often micron-sized ceramic particles. The research shows that the strength, the elastic modulus and the wear resistance of the composite material are obviously improved with the increase of the adding amount of the micron-sized ceramic particles, but the plasticity index of the composite material is reduced with the increase of the adding amount of the micron-sized ceramic particles. This results in a significant reduction in its plastic deformability. With the development of science and technology, researchers find that replacing original micron-sized ceramic particles with nano-sized ceramic particles can not only obtain good strength, elastic modulus and wear resistance, but also slow down the reduction of the plastic index of the composite material, and even some researchers find that proper addition of nano-ceramic particles to reinforce particles can not reduce the elongation.
The research on the nano ceramic particle reinforced aluminum matrix composite material at present becomes a new research hotspot of the research on the particle reinforced aluminum matrix composite material. However, with the research of the nano ceramic particle reinforced aluminum matrix composite material by researchers, it is found that how to prepare the high quality nano ceramic particle reinforced aluminum matrix composite material is the first problem to be faced. Because the intermolecular forces of the nano-ceramic particles increase significantly as the particle size decreases, the nano-particles are often clustered together and are difficult to uniformly separate in the aluminum alloy aggregate. For this reason, researchers have tried to uniformly disperse the nano ceramic particles in the aluminum matrix by many methods, but the results are not ideal, and thus there is a need for an apparatus capable of preparing the nano ceramic particle reinforced aluminum matrix composite.
