Thermal power forging is an important component in the thermal power generation industry, which needs to run for a long time in the harsh environment such as high temperature and high pressure. In order to improve the performance and life of thermal power forgings, the application of new materials is particularly important. This paper will analyze and discuss the application and development trend of new materials in the manufacture of thermal power forgings.
New material application
Composite material
Composite material is a new type of material composed of two or more materials with different properties through a certain process method. In the manufacture of thermal power forgings, the application of composite materials can effectively improve the wear resistance, oxidation resistance and corrosion resistance of forgings. For example, the mechanical properties and wear resistance of metal matrix composites can be significantly improved by adding ceramics, carbon fibers and other reinforcing materials to the metal matrix composites.
superalloy
Superalloy refers to a class of alloy materials with excellent mechanical properties and oxidation resistance at high temperatures. In the manufacture of thermal power forgings, the application of superalloy can significantly improve the oxidation resistance and corrosion resistance of forgings, and extend the service life. For example, nickel-based superalloys can maintain good mechanical properties and oxidation resistance at high temperatures, and are widely used in the manufacture of thermal power forgings.
Titanium alloy
Titanium alloy is a new type of metal material with excellent mechanical properties and corrosion resistance. In the manufacture of thermal power forgings, the application of titanium alloy can effectively improve the oxidation resistance, corrosion resistance and fatigue life of forgings. For example, Ti-6Al-4V alloy is a commonly used titanium alloy with excellent mechanical properties and corrosion resistance, and is widely used in the manufacture of thermal power forgings.
Development of new materials with higher properties
With the continuous development of science and technology, new materials with higher performance continue to emerge. In the future, the manufacturing of thermal power forgings will pay more attention to the development and application of high-performance new materials to meet higher requirements. For example, the development of new superalloys, nanomaterials, ceramic materials, etc., will provide more options for thermal power forgings manufacturing.
Innovation of new material preparation technology
The preparation technology of new materials is one of the key factors affecting the properties of materials. In the future, the manufacturing of thermal power forgings will pay more attention to the innovation and improvement of new material preparation technology to improve the performance of materials and reduce costs. For example, the use of advanced powder metallurgy technology, rapid solidification technology to prepare high-performance new materials will become a research hotspot.
Environmental protection and sustainable development
With the increasing awareness of environmental protection, the future thermal power forging manufacturing will pay more attention to environmental protection and sustainable development. The use of environmentally friendly new materials and advanced production processes to reduce energy consumption and environmental pollution will become an important development direction of thermal power forging manufacturing in the future.
This paper introduces the application and development trend of new materials in manufacturing thermal power forgings. Through the application of composite materials, superalloy, titanium alloy and other new materials, it can effectively improve the wear resistance, oxidation resistance, corrosion resistance and other properties of thermal power forgings, and extend the service life. In the future, with the continuous development of science and technology and the continuous improvement of environmental protection requirements, the application of new materials in thermal power forging manufacturing will continue to improve and innovate, and make greater contributions to the sustainable development of enterprises and the improvement of social environment.
