Embodiment 1
[0021] A method to improve the high-temperature oxidation resistance of titanium-based alloys. First, use 60-mesh iron sandpaper to polish the titanium-based alloy sample to the mirror surface, then scrub it with absorbent cotton dipped in absolute ethanol, ultrasonically clean it in acetone for 3 minutes, and finally blow it with hot air. dry to prepare polished and cleaned titanium-based alloy samples. The polished and cleaned titanium-based alloy sample (Ti-50Al) is used as the anode, and the graphite electrode is used as the counter electrode. The distance between the electrodes is 2.5cm. The constant voltage mode is used for anodic oxidation, and the anodic oxidation electrolyte used is 0.1molL -1 CeCl 3 ·7H 2 O and 0.5wt% ammonium fluoride in ethylene glycol solution, the voltage is set to 1V, the temperature is controlled at 25°C with a water bath, and after anodizing for 60min, the sample is taken out and rinsed with deionized water and then ultrasonically cleaned wi...

[0023] A method to improve the high-temperature oxidation resistance of titanium-based alloys. First, use 60-mesh iron sandpaper to polish the titanium-based alloy sample to the mirror surface, then scrub it with absorbent cotton dipped in absolute ethanol, ultrasonically clean it in acetone for 3 minutes, and finally blow it with hot air. dry to prepare polished and cleaned titanium-based alloy samples. The polished and cleaned titanium-based alloy sample (Ti-10Al) is used as the anode, and the graphite electrode is used as the counter electrode. The distance between the electrodes is 1cm. The constant voltage mode is used for anodic oxidation, and the anodic oxidation electrolyte used is 0.05molL -1 CeCl 3 ·7H 2 O and 0.1wt% ammonium fluoride in ethylene glycol solution, the voltage is set to 60V, and the temperature is controlled at 25°C by using a water bath. After anodizing for 5 minutes, the sample is taken out and rinsed with deionized water, and then ultrasonically c...
