| titleOfInvention | Preparation method of high-temperature-resistant corrosion-resistant anodic oxide film |
| abstract | The invention relates to a preparation method of a high-temperature-resistant corrosion-resistant anodic oxide film, which comprises the following steps: preparing oxidation bath solution, placing a workpiece in the bath solution for anodic oxidation treatment to form an anodic oxidation film, wherein the concentration of sulfuric acid in the oxidation bath solution is 40-100g/L, the concentration of an additive is 2-10g/L, and the additive comprises the following components: 5-15% of soluble rare earth metal salt, 2-10% of organic acid, 0.5-1% of organic acid salt, 0.5-2% of lower alcohol and the balance of water; and sealing the hole of the anodic oxide film to obtain the finished product. The beneficial effects are that: the bottleneck that the high temperature resistance of the oxide film is improved through the hole sealing process in the prior art is broken through, the high temperature resistance of the oxide film is improved through the adjustment of the pore structure of the oxide film by changing the components of the oxidation bath solution, the problem of high-temperature cracking of the oxide film is solved, and the anode oxide film with excellent performances in all aspects and high temperature resistance and corrosion resistance can be obtained by combining with a proper hole sealing process. |
