Description
Technical Field
The invention relates to the technical field of additive manufacturing, in particular to aluminum metal composite powder and a laser additive manufactured by using the same.
Background
The aluminum-based metal material has structural and functional characteristics of low density, high specific strength, corrosion resistance, high heat conductivity and the like, and is widely applied to the fields of aviation, aerospace, traffic, energy sources and the like. However, with the development of the cost and technical requirements of the application field, the traditional machining technologies such as forging, extrusion, turning and milling are difficult to meet the requirements of complex fine structures and multifunctional applications of aluminum metal parts, and the development of a new high-efficiency and low-cost fine machining technology is urgently needed. The laser powder additive manufacturing technology comprises a laser powder bed and a laser powder feeding process, wherein metal powder is directly used as a raw material according to a three-dimensional solid digital model of a part, and the metal powder is melted and deposited layer by layer under the action of laser so as to directly realize the processing and molding of the part from bottom to top. As a revolutionary metal forming process technology, a laser powder additive manufacturing technology is applied to aluminum metal, can simultaneously achieve both complex shapes and rapid forming of parts, and is receiving attention and favor in high-end manufacturing fields such as aerospace.
However, due to the characteristics of high laser reflection, high thermal conductivity, high thermal expansion and the like of aluminum, aluminum alloy is easy to form defects such as cracks in the laser additive manufacturing process. The high temperature gradient under the action of laser can easily cause the growth of columnar crystals in the solidification process of an aluminum alloy molten pool, the columnar crystals have large solidification shrinkage in the temperature reduction process, and the solidification holes are generated and further developed into solidification cracks along the crystal boundary of the columnar crystals due to the fact that liquid-phase metal cannot be timely fed. Therefore, currently, the laser powder additive manufacturing aluminum alloys capable of being practically applied are mainly some AlSi10Mg and AlSi12 high-Si aluminum alloys with high fluidity, and for high-end application aluminum alloys in high-performance 2xxx, 5xxx, 6xxx and 7xxx Al and other high-end fields, the manufacturing defects such as severe solidification cracking and the like are caused due to the large solid-liquid solidification interval, so that the application and popularization of the high-performance aluminum alloy laser additive manufacturing parts are severely limited.
In recent years, researchers at home and abroad find that inhibiting the growth of columnar crystals in the laser additive manufacturing process is an effective means for avoiding and eliminating the solidification cracking defect of the aluminum alloy. The introduction of the nano particles not only promotes the transformation of columnar crystal structure to isometric crystal in the solidification process of an SLM (Selective laser melting) molten pool of the aluminum alloy, but also strengthens an alloy matrix to improve the mechanical property of a forming material. However, with the decrease of the size of the added particles, the specific surface area of the particles is increased, the molecular force is exerted, and the nano-ceramic phase particles are mostly poorly infiltrated with aluminum metal, so that the nano-particles are extremely easy to agglomerate in the solidification process of the molten pool, and finally the improvement and adjustment effect of the solidification structure of the molten pool is difficult to effectively exert, and the occurrence probability of defects such as holes, cracks and the like of the molding material is increased. Therefore, most of the existing composite powder is obtained by adding the nano ceramic phase, the problem of cracking in the solidification process of an aluminum metal melting pool cannot be effectively solved, and the industrial application of laser powder additive manufacturing of high-performance aluminum metal materials is difficult to realize.

The aluminum alloy powder is used as a matrix, and the nano oxide ceramic particles are introduced, so that the transformation of columnar crystal structure to isometric crystal in the solidification process of the SLM molten pool of the aluminum alloy is promoted, the aluminum alloy matrix can be strengthened by the nano oxide ceramic particles, and the mechanical property of the formed material is improved.
Further, the shape of the aluminum alloy powder is spherical or nearly spherical.
Still further, the nano-oxide ceramic particles have a size of 40nm to 500 nm.

The second purpose of the invention is realized by adopting the following technical scheme:
the laser additive is prepared from the aluminum metal composite powder by a laser powder bed process or a laser powder feeding process. In the aluminum alloy matrix, ceramic oxide nanoparticles of metal elements with low solid solubility are adopted as additional nanoparticles, under the action of high-energy laser beams, the infiltration effect with aluminum metal melt is improved through the aluminothermic reduction reaction of the ceramic oxide nanoparticles in a high-temperature molten pool, the dispersion of the ceramic nanoparticles is promoted, and the growth of columnar crystals is inhibited, so that the defect of aluminum alloy solidification cracking is eliminated.
If the laser additive is prepared by a laser powder bed process, the diameter of the aluminum alloy powder is 10-80 μm. If the laser additive is prepared by a laser powder feeding process, the diameter of the aluminum alloy powder is 40-200 mu m.
The laser additive manufactured parts can be applied to the high-tech fields of aerospace and the like.

the aluminum metal composite powder for laser additive uses aluminum alloy powder as a matrix, nano oxide ceramic particles are added to induce the transformation of an aluminum alloy columnar crystal structure to an equiaxial crystal structure in the solidification process of a laser melting pool, so that the defects of gaps and cracks caused by solidification shrinkage can be effectively reduced or avoided, and the density of the formed laser additive can be more than or equal to 99%. The laser additive has the characteristics of few gaps and crack defects, low anisotropy, high mechanical strength and good processing performance, obviously improves the comprehensive performance of aluminum alloy laser additive manufacturing parts, has the advantages of simple process, low cost and the like, and is suitable for industrial popularization.
