Abstract
Mathematical model is developed for cementation of iron taking into account the diffusion of atomic carbon C through the γ phase. Analytical solutions are obtained assuming constant diffusion coefficients, firstly the analytical method proposed that test to control the process of gaseous cementation, controlled the technological parameters of the cementation such: time (t), temperature (T), initial concentration (Co), potential carbon or atmospheric concentration (Catm), and speed of the gas flow (xw), secondly to accelerate the process of the gaseous cementation. Finally the results are quantitatively compared with those obtained experimentally taking into account the micro hardness profile. In addition, it is shown that the layer cemented produced during cementation of iron can be predicted by the numerical simulation.
