Pack carburizing is a process in which carbon monoxide derived from a solid compound decomposes at the metal surface into nascent carbon and carbon dioxide. In addition to discussing the pros and cons of pack carburizing, this article provides information on the carburizing medium, compounds, furnaces, and containers used in pack 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.

Solid powder carburizing: In this method, the carburizing compound is a solid carburized, usually charcoal of 3 to 10 mm size (fines are screened off), or coke, semicoke, or coal. To accelerate the carburizing activator or energizer normally BaCO 3 and/or Na 2 CO 3 in amounts of 1030% of charcoal is added.
