Q:What are the different surface hardening techniques for special steel?
To enhance the mechanical properties and improve the wear resistance of special steel, there exists a range of surface hardening techniques that can be employed. These techniques encompass: 1. Case hardening: Through diffusion, carbon or nitrogen is introduced into the steel surface. By subjecting the steel to an environment rich in carbon or nitrogen, the atoms disseminate into the surface layer, resulting in the creation of a hardened case while maintaining a resilient core. 2. Nitriding: The process of introducing nitrogen into the steel surface to enhance its hardness is known as nitriding. By placing the steel in an environment abundant in nitrogen at elevated temperatures, a hardened surface layer is formed, exhibiting improved resistance to wear and corrosion. 3. Carburizing: Carbon is introduced into the steel surface through carburizing. By heating the steel in an environment rich in carbon, the carbon atoms diffuse into the surface layer, leading to the development of a hardened case with heightened hardness and wear resistance. 4. Induction hardening: Utilizing an induction coil, induction hardening is a localized technique for surface hardening. The steel is heated using the induction coil and then swiftly quenched, resulting in a hardened surface layer characterized by high hardness and enhanced wear resistance. 5. Flame hardening: Flame hardening is an alternative localized method for surface hardening. The steel surface is heated using a high-temperature flame and swiftly quenched. This technique generates a hardened surface layer with increased hardness and resistance to wear. 6. Laser hardening: Laser hardening is a precise and localized surface hardening technique.
