- There are several methods of surface hardening that can be used for special steel. These methods include: 1. Carburizing: This process involves heating the steel in a carbon-rich environment, such as a gas or liquid, to allow carbon atoms to diffuse into the surface of the steel. This increases the surface hardness and wear resistance of the steel. 2. Nitriding: Nitriding is a process where the steel is heated in a nitrogen-rich environment, causing nitrogen atoms to diffuse into the surface of the steel. This creates a hard, wear-resistant surface layer. 3. Induction hardening: In this method, an alternating current is passed through a coil to create a magnetic field, which induces electrical currents in the steel. The resistance to these currents generates heat, causing the surface of the steel to reach high temperatures and undergo rapid quenching, resulting in increased hardness. 4. Flame hardening: This process involves heating the surface of the steel using a flame or an oxy-fuel torch and then quenching it in water or oil. The rapid cooling from high temperatures helps to achieve surface hardening. 5. Laser hardening: Laser beams are used to heat a specific area of the steel surface, quickly raising the temperature and then rapidly cooling it with a coolant. This localized heating and cooling process increases the hardness of the treated area. 6. Plasma nitriding: In this method, the steel is placed in a low-pressure plasma chamber, where nitrogen ions bombard the surface of the steel, causing nitrogen to diffuse into the surface and form a hardened layer. Each of these methods has its advantages and is suitable for different applications and types of special steel. The choice of surface hardening method depends on factors such as the desired hardness, dimensional limitations, and the specific properties required for the application.
