Carburizing Process and Techniques Four Methods of Carburizing

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.
