Carburizing. Carburizing is a case hardening process in which the surface carbon concentration of a ferrous alloy (usually a lowcarbon steel) is increased by diffusion from the surrounding environment. Carburizing produces hard, highly wearresistant surface (medium case depths) of product with excellent capacity for contact load, good bending ...

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.

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.
