Publish Time: 2025-02-06
The application of thermoformed parts in high temperature environments is becoming more and more widespread, especially in high-tech fields such as aviation, energy, and automobiles. These parts not only have to withstand huge mechanical stress under high temperature conditions, but also face severe challenges of oxidation and corrosion. Therefore, oxidation resistance and corrosion resistance have become key indicators for evaluating the quality of thermoformed parts.When thermoformed parts come into contact with oxygen at high temperatures, oxidation reactions are prone to occur on the surface. Oxidation not only causes changes in the size and shape of the parts, but also weakens their mechanical properties and even causes material embrittlement. In order to improve the oxidation resistance of thermoformed parts, manufacturers usually use special alloy materials and surface treatment technologies. These alloy materials contain a certain amount of elements such as chromium, silicon, and aluminum, which can react with oxygen at high temperatures to form a dense oxide film, thereby effectively blocking further erosion by oxygen.In addition to oxidation resistance, the corrosion resistance of thermoformed parts is equally important. In an environment where high temperature, high humidity, and corrosive media coexist, chemical corrosion and electrochemical corrosion are prone to occur on the surface of the parts. This will lead to increased surface roughness, reduced thickness, and even cracks and perforations. In order to improve the corrosion resistance, manufacturers will select alloy materials with excellent corrosion resistance and adopt advanced surface coating technologies such as thermal spraying and electroplating to enhance the protection ability of components.It is worth noting that the oxidation resistance and corrosion resistance of thermoformed parts are not static. They are affected by many factors, such as temperature, time, medium type and concentration. Therefore, in the design and manufacturing process, manufacturers need to fully consider these factors and ensure the long-term stable operation of components in high temperature environments through reasonable material selection and process optimization.In summary, the oxidation resistance and corrosion resistance of thermoformed parts under high temperature conditions are important indicators for their quality assessment. By adopting special alloy materials and advanced surface treatment technology, manufacturers can effectively improve the oxidation resistance and corrosion resistance of components to meet the application requirements in high temperature environments. In the future, with the continuous development of materials science and manufacturing technology, the oxidation resistance and corrosion resistance of thermoformed parts will be further improved, providing more possibilities for applications in high temperature environments.
