The production method for creating a tungsten-iridium (W-Ir) nozzle inserted into an iridium (Ir) tube typically involves the following steps: Material Consolidation:
The first step involves obtaining high-quality tungsten and iridium materials. Tungsten powder can be consolidated through processes such as powder metallurgy, while iridium is available in the form of solid rods or tubes. These materials are processed to ensure they meet required purity and mechanical property specifications. Machining and Forming: The tungsten and iridium materials are machined and formed to form the outer nozzle structure and inner iridium tube. This may involve processes such as turning, milling, drilling and grinding to obtain the required dimensions and surface finish. Assembly: Insert the iridium tube into the tungsten outer structure to form a composite tungsten-iridium component. The fit between the tube and external structure is critical to ensure a strong and long-lasting bond. Connection methods: The connection of the iridium tube to the tungsten external structure can be achieved by a variety of methods, such as diffusion bonding, soldering or welding. These methods ensure a strong and reliable bond between the two materials. Finishing and Quality Control: After assembly, the infrared nozzles are finished to achieve final dimensions and surface quality. Perform quality control measures, including dimensional accuracy and material integrity checks, to verify component integrity. Testing: Finished tungsten iridium nozzles may be tested to evaluate their performance under high temperature, pressure, or corrosive conditions to ensure they meet required functional requirements. The production process of tungsten-iridium nozzles inserted into iridium tubes requires precision, expertise in handling refractory metals, and strict quality control to produce durable and high-performance components suitable for demanding applications.
Tungsten-iridium nozzles inserted into iridium tubes are commonly used in applications requiring high temperature and corrosion resistance. These composite nozzles leverage the high-temperature strength of tungsten and the corrosion resistance of iridium. Some common applications for these nozzles include:
Aerospace: Tungsten-iridium nozzles are used in rocket propulsion systems and aerospace applications where these nozzles are subject to high temperatures and corrosive environments. Semiconductor Industry: These nozzles are used in equipment used in semiconductor manufacturing processes and can withstand high temperatures and harsh chemical environments. Welding and Cutting: Tungsten-iridium nozzles are suitable for welding and cutting processes that are exposed to extreme heat and reactive gases. Industrial furnaces: They are used in industrial furnaces and high-temperature processing equipment where durability and chemical resistance are critical.
The use of tungsten-iridium composite materials allows nozzle designs to withstand the harsh conditions found in these applications, providing reliability and long life in harsh environments.
