Tungsten-molybdenum alloys are widely used and important in high-temperature plasma, mainly reflected in the following aspects:
Fusion reactor components
In nuclear fusion reactions, high-temperature plasma is the key to achieving fusion reactions. Tungsten-molybdenum alloy is often used as key components in nuclear fusion reactors due to its high melting point, good thermal stability and radiation resistance, such as the first wall facing the plasma, divertor, heat shielding structure, etc. These components need to withstand extremely high temperatures and intense particle irradiation, and tungsten-molybdenum alloys can maintain stable performance in this extreme environment.
High temperature plasma spraying and cladding
Tungsten-molybdenum alloys can be used as coatings or cladding materials on surfaces that require high-temperature plasma treatment. Through high-temperature plasma spraying or cladding technology, a dense layer of tungsten-molybdenum alloy coating can be formed on the substrate to improve the wear resistance, corrosion resistance and high temperature resistance of the substrate.
High temperature plasma generator
In high-temperature plasma generators, components such as electrodes and nozzles need to withstand high temperatures and strong electric fields. Tungsten-molybdenum alloy is suitable for manufacturing these components due to its high melting point and good electrical conductivity, ensuring the stable operation of the generator.
Aerospace field
In the aerospace field, high-temperature plasma environments also exist. Tungsten-molybdenum alloy can be used as a material for rocket engines, thrusters and other components, and can withstand extreme high temperatures and high-speed airflow.
High temperature metallurgy and smelting
In high-temperature metallurgy and smelting processes, tungsten-molybdenum alloys can be used as electrodes, crucibles and other components of smelting furnaces because of their ability to resist high temperatures and corrosion of molten metal.
Although tungsten-molybdenum alloy has many advantages and applications under high-temperature plasma, its preparation and processing are relatively difficult and costly. Therefore, in practical applications, factors such as material performance, cost, and processing difficulty need to be comprehensively considered to select the most appropriate materials and application solutions. At the same time, with the continuous advancement of science and technology and the continuous optimization of processes, the performance and application scope of tungsten-molybdenum alloys are also expected to be further improved and expanded.
