The thermal properties of cemented carbide mainly include the following aspects:
1. Thermal conductivity: Carbide has a high thermal conductivity and can effectively transfer heat. At high temperatures, this high thermal conductivity can help the alloy transfer heat quickly, allowing it to maintain stable performance in high temperature environments.
2. Thermal expansion coefficient: The thermal expansion coefficient of cemented carbide is low and it is not easy to deform in high temperature environments. This also means that in high-temperature environments, the dimensional changes of cemented carbide are smaller, which is beneficial to maintaining the stability of its mechanical properties.
3. Melting point: Cemented carbide has a higher melting point and can withstand processing and application in high temperature environments. Its high melting point allows cemented carbide to maintain the stability of its structure and properties at high temperatures.
4. Oxidation resistance: Cemented carbide has certain oxidation resistance in high temperature environments. However, it should be noted that cemented carbide will still be affected by oxidation in high temperature environments, so the requirements for anti-oxidation performance need to be determined according to specific application scenarios.
In general, the thermal performance characteristics of cemented carbide give it good stability and application potential in high temperature environments. However, issues such as its antioxidant properties and lifespan in high temperature environments still need to be considered in specific applications.
