Modelo de Difusión Sólida para Cementación Gaseosa en Producción Discontínua

Abstract

This paper’s objective consists on building a model of a production process, mainly using computer software, punctually, a steel surface treatment: gas carburizing. First, a number of tools useful for modelizing are evaluated, such as Simulink, PDE solver and COMSOL, in order to construct the model using that software which have been qualified as apt for the study object. After having built the model, and established different inputs (solid geometry, time, temperature, etc.) the results are obtained and analyzed with the end of verifying that the results are approximate to the real process. The advantage about these kind of models is that enables the independence from traditional grids and graphs to design the process, which frequently show values discontinuously or in not suitable conditions. This way, it is possible to simulate the process prior to the design with an amount of specifications widely more approximate to reality than the obtained by the use of graphs.
