Problems solved by technology

[0002] Magnesium alloy AZ31B is a widely used wrought magnesium alloy, which has potential application value in the fields of automobile, aerospace, electronics, etc. However, the poor corrosion resistance, low strength and hardness of magnesium alloys greatly limit the application of magnesium alloys. sex
[0003] At present, there are many ways to improve the corrosion resistance and mechanical properties of magnesium alloys, such as grain refinement, component purification, surface coating, extrusion molding, metallurgical doping with boron carbide, etc.; but for large-area magnesium alloys The processing of the plates is not ideal enough to meet the requirements of metal products for parts. The strength, hardness and corrosion resistance are all at a lower level. The extruded plates are easy to crack and fall off, which has become a major problem in the processing process. disadvantages
