Description

Technical Field

[0001] This utility model belongs to the field of magnesium alloy surface treatment technology, and in particular relates to a spin-drying device for magnesium alloy anodizing process. Background Technology

[0002] Magnesium alloys are lightweight structural materials with great application potential. They possess advantages such as high specific strength and specific stiffness, good thermal and electrical conductivity, good vibration damping performance, excellent electromagnetic shielding performance, and ease of machining. They have extremely important application value and potential prospects in aerospace, automotive, electronics, machinery, military, and nuclear industries. However, magnesium has high chemical reactivity and an extremely negative standard equilibrium potential (-2.36V), which leads to corrosion problems, becoming one of the main bottlenecks restricting the widespread application of magnesium and magnesium alloys. Therefore, improving the corrosion resistance of magnesium alloys has always been an important research topic for technicians in this field. Anodizing technology, due to its advantages of simple production process, large film area formed in one step, low investment in production equipment, and low processing cost, has become the most basic and widely used surface treatment method for magnesium and magnesium alloys. Anodized films can also provide a good substrate for coating with paints, coatings, and other organic coatings, and their porous structure can be used for coloring to meet decorative requirements.

[0003] Chinese patent CN201610343186.X provides a magnesium alloy anodizing electrolyte and a method for anodizing magnesium alloys. The electrolyte components include hydroxide, silicate, phytic acid, isonicotinic acid-N-oxide, and solvent. The method involves placing the magnesium alloy in the magnesium alloy anodizing electrolyte and performing anodizing treatment using a DC power supply in constant current mode. The current density is controlled at 8~15mA / cm2, the oxidation time is 20~40min, and the electrolyte temperature remains below 30℃ throughout the oxidation process.

[0004] However, in actual processing, the removal efficiency of water stains on the surface of existing magnesium alloy products is slow and the required cycle is long, which reduces production efficiency.

[0005] To address this issue, this invention presents a spin-drying device for the anodizing process of magnesium alloys. Utility Model Content
