With the continuous development of construction engineering, building forgings play an important role in various mechanical equipment and structures. Due to the different working environment and use requirements, building forgings need to have different wear resistance and corrosion resistance. In order to meet these requirements, surface treatment technology is also widely used. This paper introduces the wear resistance and surface treatment technology of building forgings.
Forgings for construction refers to the construction machinery and equipment and structural components made by forging process. Due to the high temperature and high pressure treatment of the material in the forging process, the forging has good mechanical properties and stability. Wear resistance refers to the ability of the material to resist wear, while surface treatment technology refers to the formation of a protective layer on the surface of the material through physical, chemical or composite methods to improve its wear resistance, corrosion resistance and aesthetics.
At present, there are the following problems in the research and application of the wear resistance and surface treatment technology of building forgings: (1) Insufficient research and development of wear-resistant materials, resulting in wear resistance can not meet the needs of high strength and high frequency work; (2) A wide variety of surface treatment technologies, lack of standardized and standardized management, affecting the quality and consistency of treatment; (3) The balance between wear resistance and corrosion resistance is difficult to master, and corrosion resistance is often ignored.
The wear resistance of building forgings is mainly achieved through material selection and surface treatment. Commonly used wear-resistant materials include high-strength steel, alloy steel, carbide and so on. Surface treatment technology mainly includes coating, coating, heat treatment, etc., of which coating technology can be divided into physical coating and chemical coating. The main principle of these technologies is to use the high hardness and high wear resistance of materials to improve the wear resistance of forgings.
The surface treatment of building forgings mainly includes the following steps: (1) Material selection: select materials with high strength, wear resistance and corrosion resistance according to the requirements of use; (2) Production process: forging, roughing, semi-finishing, finishing and other processes; (3) Surface treatment: The use of physical or chemical methods to form a protective layer on the surface of the forging to improve its wear resistance, corrosion resistance and aesthetics.
The advantages of building forgings wear resistance and surface treatment technology are: (1) improve the wear resistance and corrosion resistance of forgings and extend their service life; (2) Optimize the performance of materials, improve the utilization rate of materials and economic benefits; (3) Beautify the appearance of products, improve the added value of products and market competitiveness. However, these technologies also have some shortcomings, such as high processing cost, long processing cycle, and possible environmental pollution in the process.
In summary, the wear resistance and surface treatment technology of building forgings are key factors to improve the performance of mechanical equipment and structural components. In practical applications, appropriate wear-resistant materials and surface treatment technology should be selected according to the specific working environment and requirements, and standardized and standardized management should be strengthened to improve the quality and reliability of forgings. At the same time, further research and development of more efficient, environmentally friendly and economical surface treatment technologies and materials are needed to meet the increasing engineering needs.
