The application of tungsten-molybdenum alloys in high-temperature plasma does face a series of problems. These problems are mainly due to the strict requirements on material properties in the extreme environment of high-temperature plasma.
First, high-temperature plasma environments require materials with excellent high-temperature resistance. Although tungsten-molybdenum alloy has a high melting point, its properties may change under long-term high-temperature exposure, such as thermal expansion and thermal creep, which may affect its stability and reliability under high-temperature plasma. sex.
Secondly, the high-temperature plasma environment is highly radiative, which places high requirements on the radiation resistance of materials. Although tungsten-molybdenum alloy has certain radiation resistance, under long-term high-dose radiation, its microstructure and properties may undergo irreversible changes, such as radiation hardening, radiation swelling, etc., thus affecting its service life and Performance stability.
In addition, high-temperature plasma environments may also cause corrosion and oxidation of materials. Although tungsten-molybdenum alloy has good resistance to certain corrosive media, in a high-temperature plasma environment, it may chemically react with certain components in the plasma, causing surface corrosion or oxidation, thereby affecting its performance and use. life.
Finally, the processing and preparation of tungsten-molybdenum alloys is also a big challenge. Due to its high melting point and hardness, tungsten-molybdenum alloys are difficult to process and their preparation costs are high. This limits its application scope in the field of high-temperature plasma to a certain extent.
In summary, the application of tungsten-molybdenum alloys under high-temperature plasma faces problems in high-temperature resistance, radiation resistance, corrosion and oxidation, and processing and preparation. In order to overcome these problems, researchers are actively exploring new material preparation processes, surface treatment technologies, and material performance optimization methods in order to improve the performance and service life of tungsten-molybdenum alloys under high-temperature plasma.
