Once the importance of the carbon transfer was understood in the 19th century, the first industrial carburizing process using a carburizing powder was developed. In this technique, the parts were placed in a box filled with a carburizing powder, which consisted of charcoal, anthracitic coal, or coke. The box was sealed and placed into the furnace.

5. It is difficult to use directquenching in pack carburising. Method # 2. LiquidCarburising: When the enrichment of steel surface with carbon takes place by immersing the steel to be carburised in a molten salt maintained at an appropriate temperature (in range 850°C to 950°C), it is called liquid carburising.

Liquid carburizing involves placing parts in a bath of a molten carboncontaining material, often a metal cyanide. Finally, pack carburizing is a process which involves placing steel items into a furnace in close proximity to highcarbon items. These highcarbon items include everything from carbon powder to castiron particles, and more.

1. When an active carburizer (charcoal mixed with barium or sodium carbonates) is used, the carburizing temperature of dense iron powder parts should not exceed 1223° K, as otherwise blister formation, swelling, and layering may take place on the surface of the parts. It is recommended that carburizing should be performed at ° K.

Components are packed in an environment with a high carbon content such as cast iron shavings or carbon powder. The components are heated with the production of carbon monoxide, which is a reducing agent. The reduction occurs on the steel surface with the release of carbon that is diffused into the surface because of high temperatures.
