Carburising uses the following compounds for heat treatment of me

SOLUTION

Carburising:

In this operation, the steel is heated to a suitable temperature in a carbonaceous atmosphere and kept at that temperature until the carbon has penetrated to the depth required.

Nitriding:

In the nitriding process, the surface is enriched not with carbon, but with nitrogen. There are two systems in common use, gas nitriding and salt bath nitriding.

Carburising is the process of saturating the surface layer of low carbon steels at 850° - 950°C with carbon from a carbonaceous source capable of giving up its carbon to the metal.

There are three methods of carburising:

• Solid or pack carburising
• Gas carburising
• Liquid carburising
