1. Tempering process
Tempering is a heat treatment process performed after quenching, the purpose of which is to reduce the brittleness of the camshaft and improve its toughness. During the quenching process, the camshaft is heated to a certain temperature and then cooled rapidly to form a martensitic structure, which greatly improves the hardness of the AUDI Car Camshaft and also brings about the problem of increased brittleness. The camshaft after quenching usually needs to be tempered.
During the tempering process, the camshaft is heated to a certain temperature and maintained for a period of time, and then slowly cooled. This process can achieve a balance between the hardness and toughness of the camshaft, maintaining a high hardness and avoiding the risk of fracture caused by excessive brittleness. Through tempering, the service life of the camshaft has been significantly improved, and it can better withstand various stresses and wear during the operation of the engine.
2. Carburizing process
Carburizing is a surface heat treatment process designed to increase the carbon content on the surface of the camshaft, thereby enhancing its hardness and wear resistance. During the carburizing process, the camshaft is placed in a carburizing furnace and reacts chemically with the carburizing medium (such as kerosene, alcohol, etc.) at high temperature to allow carbon atoms to penetrate into the surface layer of the camshaft.
After carburizing, a high-hardness carbide layer is formed on the surface of the camshaft, which can significantly improve the wear resistance and fatigue resistance of the camshaft. Since the carburizing treatment is only performed on the surface of the camshaft, its interior still maintains good toughness, avoiding the brittleness problem caused by overall hardening. This surface strengthening method has significant advantages for parts such as camshafts that are mainly subjected to surface wear and contact.
3. Quenching process
Quenching is the most critical step in the heat treatment process and is also the core process for improving the hardness of the camshaft. During the quenching process, the camshaft is heated to a certain temperature (usually higher than the critical point Ac3 or Ac1) to change the internal structure, and then quickly cooled to form a martensitic structure.
The hardness of the camshaft after quenching is significantly improved, and it can better resist various wear and impact during engine operation. Due to the high strength and hardness of the martensitic structure, the fatigue resistance of the camshaft has also been significantly enhanced. The quenching process also brings about the problem of increased brittleness, and subsequent tempering treatment is usually required to balance hardness and toughness.
4. Improvement of camshaft performance by comprehensive heat treatment process
Through the comprehensive use of heat treatment processes such as tempering, carburizing and quenching, KORBOR can significantly improve the key performance of the camshaft:
Improved hardness: Under the combined action of quenching and carburizing processes, a high-hardness carbide layer is formed on the surface of the camshaft, which significantly improves its wear resistance and scratch resistance.
Enhanced toughness: The tempering process reduces the brittleness caused by quenching, so that the camshaft has good toughness while maintaining high hardness, and can better withstand various stresses and impacts.
Improved fatigue resistance: Since the quenching and carburizing processes enhance the surface hardness and internal toughness of the camshaft, its fatigue resistance has been significantly improved, and it can run stably for a long time without being easily damaged.
Extended service life: The comprehensive heat treatment process has comprehensively improved the overall performance of the camshaft, thereby significantly extending its service life and reducing the replacement frequency and maintenance costs.
