It forms a hard layer of nitrides, which significantly increases the surface hardness, wear resistance, and fatigue strength of the steel. 2. Carbonitriding: Carbonitriding is a similar process to nitriding, but it involves the diffusion of both carbon and nitrogen into the steel surface. This technique increases the surface hardness and also improves the wear resistance and fatigue strength of the steel. 3. Case hardening: Case hardening involves the addition of a hard, wear-resistant layer to the surface of the steel. This can be achieved through processes like carburizing or carbonitriding, where carbon is introduced into the surface layer, transforming it into a high-carbon martensitic layer. 4. Shot peening: Shot peening is a technique that involves bombarding the steel surface with small, high-velocity shots of media, such as steel, ceramic, or glass beads. This process induces compressive stresses on the surface, improving its fatigue strength and resistance to stress corrosion cracking. 5. Electroplating: Electroplating is a common technique used to apply a thin layer of metal coating onto the steel surface. This can be done with various metals like zinc, nickel, or chromium, providing protection against corrosion, improving aesthetics, and enhancing wear resistance. 6. Physical vapor deposition (PVD): PVD is a coating technique that involves depositing thin layers of material onto the steel surface through a vacuum process. This technique can be used to apply coatings like titanium nitride (TiN), which provides excellent wear resistance and reduces friction. 7. Laser surface modification: Laser surface modification techniques, such as laser hardening or laser alloying, use a high-energy laser beam to selectively heat and modify the steel surface. This process can improve hardness, wear resistance, and corrosion resistance. These surface modification techniques can be tailored to meet specific requirements, enhancing the properties of special steel for various applications in industries such as automotive, aerospace, and tooling.
