Abstract

The invention discloses an anodic oxidation die-casting aluminum alloy material and a preparation method thereof. The anodic oxidation die-casting aluminum alloy material comprises, by mass percent, 2.5-3.5% of Mg, 0.8-1.2% of Mn, 0.2-0.5% of Co, 0.1-0.2% of Cr, 0.01-0.03%of Sr, less than or equal to 0.2% of Si, less than or equal to 0.15% of Fe, less than or equal to 0.05% of Cu, and the balanceAl. According to the material and the method, by optimizing components of an aluminum-manganese system die-casting aluminum alloy material, the material can achieve a good anodic oxidation effect, thedefects of aluminum alloy surface hardness, wear resistance and the like are overcome, and the application range is expanded; and meanwhile, the preparation method is simple, the corrosion effect ofan aluminum alloy on a casting crucible can be reduced, meanwhile, the plasticity of the aluminum alloy is increased, the generation of defects such as thermal cracks, shrinkage cavities, shrinkage porosity and the like is reduced, a honeycomb porous structure on the surface of an anodic oxidation film generated on the surface of the aluminum alloy through the anodic oxidation process is uniform in dye coloring, and the compact anodic oxidation film formed after pore sealing has high surface hardness, wear resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of aluminum alloy materials, in particular to an anodized die-casting aluminum alloy material and a preparation method thereof. Background technique [0002] Aluminum and aluminum alloys have the characteristics of low density, high specific strength, good plasticity, excellent mechanical properties, low thermal expansion coefficient, good corrosion resistance, excellent electrical and thermal conductivity, easy processing, and recyclability. It has been widely used in fields such as machinery manufacturing, shipbuilding, chemical industry and packaging, and has become the most widely used non-ferrous metal material in modern industry (especially the automobile industry), and it is also a green and sustainable non-ferrous metal Material. However, the problem of aluminum alloy material is that its strength is not high and its machinability is poor, which limits its use. At the same time, with the development of the a...
