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 ...
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.

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 1030% of charcoal is added. Download Solution PDF.
4. Solid Carburizing (Pack Carburizing) In solid or 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. Carburizing containers are made of carbon steel, aluminumcoated carbon steel, or ironnickelchromium heatresisting alloys.

The pack carburizing process is typically conducted by surrounding the steel in a pit furnace or steel box furnace with granules of charcoal or charcoal plus coke. An "activator" for the charcoal, such as barium borate (BaBO 3 ) or barium carbonate (BaCO 3 ) is added to facilitate the release of CO 2, which then reacts with the ich ...
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.
