A mathematical model has been developed for the gas carburizing (diffusion) process using Finite Volume Method. The computer simulation has been done for an industrial gas carburizing process. Model's predictions are in very good agreement with industrial experimental data and with the data collected from the literature. Study of various mass transfer and diffusion coefficients has been done in order to suggest that which correlations should be used for the gas carburizing process. The model (we call it GasCarb) has been made user friendly using Graphical User Interface so that it can be used in the industry on day-to-day basis. Sensitivity analysis shows that case depth increases as the carburizing time, atmospheric carbon potential of the process increases. Case depth also increases with increase in diffusion and mass transfer coefficients. This software can control the process online and gives an in-depth analysis of the process.
GasKarb is a industrial grade software which is used for simulating the one-dimensional gas carburizing process for the plain carbon and alloy steels. It can also control the process on-line. The code uses finite volume techniques to solve numerically the diffusion equations.
