Liquid carburizing is a process used for case hardening steel or iron parts. The parts are held at a temperature above Ac1 in a molten salt that introduces carbon and nitrogen, or carbon alone, into the metal. Most liquid carburizing baths contain cyanide, which introduces both carbon and nitrogen into the case.

Process of Cyaniding:
1. Definition: Cyaniding is a surface hardening process used to increase the hardness and wear resistance of steel components.
2. Procedure:
- The steel component is heated in a furnace with a mixture of sodium cyanide and charcoal powder.
- At high temperatures, carbon and nitrogen diffuse into the steel surface, forming a hardened layer.
3. Benefits:
- Cyaniding enhances the surface hardness of steel, making it more resistant to wear and corrosion.
- It also improves the fatigue strength and overall durability of the steel component.
4. Applications:
- Cyaniding is commonly used in the manufacturing of gears, shafts, and other components that require high wear resistance.
- It is particularly effective in applications where the component is subjected to repeated contact and friction.
5. Comparison with Other Processes:
- Cyaniding is different from simply dipping steel in a cyanide bath, as it involves a chemical reaction with the steel surface.
- Unlike obtaining cyanide salts, cyaniding is a metallurgical process that modifies the steel itself to improve its properties.
In conclusion, cyaniding is a specialized heat treatment process that enhances the surface hardness and wear resistance of steel components by adding carbon and nitrogen through a reaction with cyanide salts.
