When you use the Carburization interface, you can define the carbon concentration of the environment surrounding the component to be carburized. This is done by selecting the type of Carburizing Cycle. You can either specify the carbon concentration directly, as a function of time, or you can use the built-in Boost-diffuse cycle. In the latter situation, you use a simple cycle where the carbon potential cpot is at a high value for an initial time (), and after this boost period, the carbon potential is lowered, and the diffuse stage begins.
