How does the shot peening surface treatment technology in instrument manufacturing enhance the strength of instrument components?

　　In the instrument manufacturing industry, the strength and durability of instrument components are crucial factors to ensure product performance. In order to enhance the strength and durability of instrument components, shot peening surface treatment technology has emerged. This technology sprays high-speed particles (usually steel balls or steel sand) onto the surface of the workpiece, thus creating microscopic indentations and scratches on the surface of the workpiece, forming residual compressive stress. This treatment method can significantly improve the surface hardness, fatigue resistance, and wearresistance of the material, thereby effectively enhancing the strength of instrument components.

I. Working Principle of Shot Peening Surface Treatment Technology

　　The working principle of shot peening surface treatment technology is to use high-speed impacting particles (such as steel shot, steel sand, etc.) to impact the surface of the workpiece, forming residual compressive stress, thereby improving the hardness, wear resistance, fatigue strength, and corrosion resistance of the material surface. The main steps of shot peening surface treatment technology include: material preparation, workpiece pretreatment, shot peening, and post-treatment. Firstly, the workpiece to be treated is pre-treated to remove the surface oxide layer and impurities; then, theworkpiece surface is impacted by high-speed jetting of steel shot or steel sand; finally, the treated workpiece is cleaned and dried to ensure the effectiveness of the surface treatment.

　　II. Advantages of Shot Peening Surface Treatment Technology

Shot peening surface treatment technology is widely used in the instrument manufacturing industry, such as instrument components, precision mechanical components, and electronic components. Through shot peening surface treatment technology, the strength and durability of instrument components can be significantly improved, extending their service life and thereby enhancing the overall performance and reliability of the instrument.

In summary, shot peening surface treatment technology is an effective means to enhance the strength and durability of instrument components. By forming residual compressive stress on the surface of the workpiece, it can significantly improve the hardness, wear resistance, fatigue strength, and corrosion resistance of the workpiece surface, thereby enhancing the fatigue resistance and durability of the workpiece, and extending its service life. With the wide application of shot peening surface treatment technology in the instrument manufacturing industry, its advantages in improving the strength and durability of instrument components will be recognized and applied more widely.
