Nimonic alloys have excellent high temperature properties such as high strength, good oxidation resistance and creep resistance. This enables Nimonic turbine impellers to operate stably in harsh working environments with high temperature, high pressure and high speed.
Structurally, turbine impellers usually have carefully designed blade shapes and layouts to achieve efficient energy conversion. Its manufacturing process is extremely demanding, requiring precision machining and strict quality control.
Excellent high temperature strength, able to maintain structural stability and performance in high temperature environment.
Excellent anti-oxidation and anti-corrosion performance, extending service life.
Good creep resistance, can withstand long-term high temperature and stress.
High thermal fatigue performance, adapt to frequent temperature changes.
Excellent wear resistance, reducing wear of components.
In the aerospace field, the new generation of aircraft engines has higher and higher requirements for performance and reliability. The application of Nimonic turbine impellers will help improve the efficiency and thrust of the engine, reduce fuel consumption and emissions, and meet the aviation industry’s pursuit of environmental protection and energy conservation.
In the energy field, especially gas turbines, the role of power generation and energy conversion is becoming increasingly important. Nimonic turbine impellers can improve the efficiency and output power of gas turbines, adapting to the growing energy demand and the development trend of clean energy.
In the industrial field, the upgrading of various large-scale industrial equipment also provides more application opportunities for Nimonic turbine impellers. For example, in the petrochemical, metallurgical and other industries, high-efficiency compressors and pumps require high-performance turbine impellers to improve production efficiency and reduce operating costs.
Nimonic alloy billets are heated and hammered or extruded to form the shape of the impeller. Forging can increase the density and strength of the material.
Liquid Nimonic alloy is poured into a mold and the shape of the impeller is obtained after cooling and solidification. Casting can produce impellers of complex shapes, but may require subsequent processing and heat treatment.
The forged or cast impeller is processed using tools such as lathes, milling machines, and drilling machines to achieve precise size and shape requirements.
Multiple Nimonic alloy parts are welded together to form a complete impeller. Welding requires appropriate welding processes and techniques to ensure welding quality.
The microstructure of Nimonic alloy is changed and its performance is improved through the process of heating and cooling. Heat treatment usually includes steps such as solution treatment and aging treatment.
The impeller is surface treated, such as spraying, plating, etc., to improve its corrosion resistance and wear resistance.
