The invention discloses an aluminum alloy micro-arc oxidation plating solution and a preparation method and application thereof. The aluminum alloy micro-arc oxidation plating solution comprises water, potassium hydroxide and the following preparation raw materials: 8-15g / L of sodium hexametaphosphate; 10-18 g / L of sodium silicate; 10 to 15 g / L of sodium metavanadate; 10 to 18g / L of sodium molybdate; 1-5 g / L of ethylene glycol; 2-5 g / L of beta-sodium glycerophosphate; 3-6 g / L of sodium hexafluorotitanate; 1-3g / L of boric acid; the content of aluminum oxide in the alkaline aluminum oxide sol is 0.1-0.3 g / L; and the pH value of the micro-arc oxidation plating solution is 9-12. The plating solution is suitable for surface treatment of the aluminum alloy, the hardness, the wear resistance and the corrosion resistance of the material can be remarkably improved, and the surface can be flatter and smoother. The invention further provides a preparation method and application of the aluminum alloy micro-arc oxidation plating solution.

This invention discloses a polishing slurry, its preparation method, and its application, relating to the field of polishing slurry technology. The polishing slurry of this invention comprises silica abrasive, citric acid, and sodium citrate, with a pH < 7. It effectively controls metal ion contamination during the polishing process of synthetic quartz, improves the removal rate during the polishing of quartz glass substrates, and reduces the surface roughness of the quartz. It synergistically optimizes chemical corrosion and mechanical removal, achieving an atomically smooth, scratch-free, and subsurface-damage-free quartz glass substrate surface while maintaining a high material removal rate. Furthermore, it possesses characteristics such as low contamination, easy cleaning, and environmental friendliness.
