The research on the surface treatment and durability improvement technology of automobile forgings is to improve the surface performance and prolong the service life of the forgings. The following are some common surface treatment technologies and durability enhancement technologies: Surface coating technology: The surface coating technology commonly used in automotive forgings includes electroplating, electroless plating, hot dip plating, spraying, etc. These coatings can increase the corrosion resistance, wear resistance and oxidation resistance of forgings. Heat treatment technology: Through a reasonable heating and cooling process, the grain structure and organizational state of the forging can be changed, thereby improving its hardness, strength and wear resistance. Commonly used heat treatment technologies include quenching, tempering, normalizing and so on. Nitriding treatment: By injecting nitrogen on the surface of the forgings to form a hard nitride layer, it can significantly improve the hardness, wear resistance and corrosion resistance of the forgings. Surface modification technology: including shot peening, grinding, machining and other methods, by changing the shape and structural characteristics of the forging surface, improve its surface finish, fatigue resistance and corrosion resistance. Surface strengthening process: including laser treatment, electron beam treatment, plasma treatment and other technologies, through the generation of high energy heat source or ion beam on the surface of the forging, improve the mechanical properties and wear resistance of the surface. Corrosion protection technology: including anti-corrosion coating, anti-rust agent, etc., used to protect the surface of the forging from corrosion and oxidation, extend its service life. These surface treatment and durability enhancement technologies can be selected and applied according to specific needs and application scenarios. Through the research and application of these technologies, the quality and performance of automobile forgings can be effectively improved, their service life can be extended, and the overall reliability and safety of automobiles can be improved.
