  - The method of enriching surface layer of low carbon steel with carbon is called as carburising. This method is used to produce a hard case by diffusing atomic carbon in surface layer of component. This makes the surface layer hard and wear resistant.
  
  - Carburising is generally carried at 900°C to 950°C. Fully austenite phase is required in this technique as carbon has more solubility in austenite.
  
  - Different types of carburising methods are as follows: Pack carburizing, liquid carburizing and gas carburizing.
  
  Gas carburizing:
  
  - In this method, metallic components are heated in gaseous atmosphere. Carbon atom is deposited by decomposition on the surface of components.
  
  - This method has low cost and clean working conditions. It has high flexibility and accommodates components of each size and shape.
