Problems solved by technology

[0003] At present, the technology in the field of magnesium alloy processing in the market is not particularly mature, and the existing magnesium alloys will have some shortcomings. The most basic problem is that magnesium alloys are easy to be oxidized, exposed to the air, and will soon be oxidized to black. Due to the release of hydrogen gas during processing, there will be more and more hydroxide ions, and the pH will increase accordingly, and the magnesium alloy will be more and more easily corroded by the high pH processing industry, and the workpiece cannot meet the processing requirements.
