Zinc alloy is a high-performance environmentally friendly material, which has great potential in replacing copper alloys. In order to further improve the quality and mechanical properties of the cast alloy after the coagulation of the zinc alloy, starting from the existing experimental conditions, during the solidification of the zinc alloy, nitrogen was used to pressure treat the solidification of the zinc alloy, and on this basis, machinery was added. Vibration treatment. After the material solidifies, macroscopic microstructure observation and tensile experiments are performed on the casting, and data analysis is performed.
The experimental results show that compared with the solidification under normal conditions, the quality of the macrostructure of the casting obtained by the solidification of the zinc alloy die casting under pressure and mechanical vibration is effectively improved, and the degree of porosity and shrinkage on the outer surface of the metal becomes smaller. Observation and analysis of the appearance of the casting can preliminary judge that the quality of the internal organization has been improved.
Zinc metal has good calenderability, wear resistance and corrosion resistance, and can be made into alloys with better physical and chemical properties with a variety of metals. For this reason, research and development of new zinc alloy die castings has obvious economic and social benefits. In order to meet the requirements of the rapid development of modern industry, it is particularly important to accelerate the development of zinc alloy materials and improve the level of zinc alloy casting.
