Determine the carbonization time required to reach a concentration of 0.30% by weight of carbon at 4 mm in a steel alloy originally containing 0.10% by weight of carbon. Consider that the concentration on the surface must be maintained at 0.90% by weight of carbon and that the treatment will be carried out at a temperature of 110 ºC.
