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.

Pack Carburization. Pack carburization 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 cast iron particles, and more. After you've inserted these items, they will be heated with the use of carbon monoxide.

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.
