Tungsten and molybdenum products are widely used in the vacuum coating industry, mainly because tungsten and molybdenum have a series of excellent properties, making them one of the ideal materials for many vacuum coating applications. The following are some of the main applications of tungsten and molybdenum products in the vacuum coating industry:
- Target: Tungsten-molybdenum alloy is commonly used to manufacture targets for physical vapor deposition (PVD) and chemical vapor deposition (CVD). These targets are used to deposit uniform thin films on the surface of materials to improve their performance, appearance or other characteristics.
- Thermal evaporation boat: During the vacuum coating process, it is usually necessary to heat the material to be evaporated to its evaporation temperature. Tungsten-molybdenum alloy has become one of the ideal materials for thermal evaporation boats due to its high melting point and good heat resistance.
- Cathode: In the physical vapor deposition (PVD) process, the cathode is used to generate an ion beam to evaporate the target material and deposit it on the substrate. Tungsten-molybdenum alloys are used to make cathodes and are favored for their good electrical conductivity and heat resistance.
- Vacuum furnace components: Vacuum coating equipment usually requires high temperature and corrosion resistant components. Tungsten-molybdenum alloy is often used to manufacture components of vacuum furnaces, such as heaters, furnaces, and thermal blocks due to its excellent high temperature resistance and chemical stability.
- Observation window: During the vacuum coating process, it is sometimes necessary to observe the coating process to ensure the quality and uniformity of the film. Tungsten-molybdenum alloy is suitable as a material for viewing windows due to its high transparency and corrosion resistance.
In summary, tungsten and molybdenum products are widely used in the vacuum coating industry, and they provide important support for improving the efficiency and quality of the coating process.
