Thermal power forging plays an important role in thermal power generation equipment, and its performance and quality directly affect the operation safety and efficiency of equipment. As the key material in the manufacture of thermal power forgings, wear-resistant materials are of great significance for improving the service life of equipment and reducing maintenance costs. With the continuous development of science and technology, new wear-resistant materials continue to emerge, providing more choices for thermal power forging manufacturing. In this paper, the application scenario and development trend of new wear-resistant materials in thermal power forging manufacturing will be discussed.
Wear-resistant materials refer to materials that can maintain high wear resistance under wear conditions. At present, commonly used wear-resistant materials mainly include high manganese steel, high chromium cast iron, wear-resistant alloy steel and so on. These materials have been widely used in the manufacture of thermal power forgings, but their wear resistance, impact resistance and other properties need to be improved.
In recent years, some new wear-resistant materials have gradually attracted attention, such as nanocomposites, ceramic composites, polymer composites and so on. These new wear-resistant materials have excellent wear resistance, impact resistance and corrosion resistance, providing more options for thermal power forging manufacturing.
In this paper, several new wear-resistant materials were selected, including nano-composites, ceramic composites and polymer composites. The preparation technology, structure and wear resistance of these materials were studied by literature review and experiment.
nanocomposite
Nano-composite material is a composite material composed of nano-level particle reinforcement and matrix. In this paper, carbon nanotubes and aluminum-based nanocomposites are selected for research. Carbon nanotubes reinforced aluminum matrix nanocomposites were prepared by ball milling mixing and hot pressing sintering. The experimental results show that the material has higher wear resistance and impact resistance, and its wear resistance is better than that of traditional high manganese steel and high chromium cast iron.
Ceramic composite
Ceramic composite material refers to the composite material composed of ceramic reinforcement and matrix. In this paper, alumina and silicon carbide ceramics are selected for research. Alumina and silicon carbide ceramic composites were prepared by powder metallurgy. The experimental results show that the material has higher wear resistance and corrosion resistance, and its wear resistance is better than that of traditional high manganese steel and high chromium cast iron.
Polymer composite
Polymer composite material refers to the composite material composed of polymer matrix and reinforcement. In this paper, polyimide and carbon fiber are selected for research. Carbon fiber reinforced polyimide polymer composites were prepared by solution mixing and hot pressing. The experimental results show that the material has higher wear resistance and impact resistance, and its wear resistance is better than that of traditional high manganese steel and high chromium cast iron.
The new wear-resistant material has excellent wear resistance, impact resistance and corrosion resistance, and can be widely used in the manufacture of thermal power forgings. For example, in the wear-resistant parts of thermal power forgings, nano-composite materials or ceramic composite materials can be used to replace the traditional high-manganese steel and high-chromium cast iron to improve the wear resistance and service life of the parts. In the high wear environment, polymer composite materials can be used to prepare wear-resistant coatings to improve the wear resistance and impact resistance of the equipment. In addition, the new wear-resistant material can also be applied to the sealing parts of thermal power forgings to improve the corrosion resistance and sealing performance of the parts.
In this paper, the application scenario and development trend of new wear-resistant materials in the manufacture of thermal power forgings are studied. By comparing the properties and applications of different new wear-resistant materials, it is found that these materials have wide application prospects in the manufacture of thermal power forgings. In the future, the preparation process, organizational structure and performance characteristics of new wear-resistant materials can be further studied in order to improve the performance of materials and reduce costs. At the same time, the application of new wear-resistant materials in other fields can also be explored to expand its application range.
