Carburising

 Carburising is the process in which carbon atoms are introduced onto the surface of low carbon steels to produce a hard case of surface, while the interior or core remains soft.

1. What is Meant by Carburising Process?

✓ Carburising is the process in which carbon atoms are introduced onto the surface of low carbon steels to produce a hard case of surface, while the interior or core remains soft.

✓ Steels for carburising should have carbon from 0.10 to 0.20%. 

2. Process of Carburising

In carburisation, when a piece of low-carbon steel is placed in a carbon saturated temperature, then the carbon will diffuse or penetrate into the steel and carburising it.

3. Methods of Carburising

The carburising i.e., the process of adding carbon to a metal surface, can be accomplished by the following three methods.

1. Pack carburising,

2. Gas carburising, and

3. Liquid carburising (or cyaniding).

This classification is based on the form of the carburising medium used.
