[0002] Metal spraying is a surface treatment technology that forms a metal coating by spraying metal powder or metal particles onto the surface of the substrate through a high-speed airflow. This technology is widely used in the fields of construction, automobiles, aerospace, home appliances, furniture, etc. to improve the appearance, corrosion resistance and wear resistance of the product. The process of metal spraying includes pretreatment, spraying and post-treatment. The pretreatment is to remove dirt, oil stains and other impurities on the surface of the substrate to improve the adhesion of the substrate and the durability of the coating. Spraying is to spray metal powder or particles at high speed through a spray gun onto the surface of the substrate to form a coating. Post-treatment includes curing, finishing and inspection to ensure the performance and quality of the coating. Metal spraying has many advantages, such as thick, uniform, beautiful coating, strong adhesion, good corrosion resistance and wear resistance, etc. In addition, metal spraying can also choose different metal powders or particles according to different needs to achieve the desired performance and appearance effects. However, metal spraying also has some disadvantages, such as certain restrictions on the shape and size of the substrate, and the coating may have problems such as tiny holes and peeling. Therefore, in practical applications, it is necessary to select appropriate surface treatment technology and materials according to specific circumstances to achieve the best effect.
