The carburizing process occurs in accordance with thermodynamical laws, carburizing rate being determined by the carbon transfer from gaseous atmospheres to metallic surfaces, and by the kinetics of reaction, also. The carburizing components flow intensity, for various gaseous atmospheres, is determined by the carbon concentration gradient between gas and metal surface and by the carbon transfer coefficient {beta}, which is directly related with gaseous composition of atmosphere, specially with %COx%H{sub 2}. The higher the value of pCOxpH{sub 2}, the carburizing rate is more intense. With a mathematical model performed by the authors, the compositions of the gaseous atmospheres having a maximum value of pCOxpH{sub 2}, for maximum value of a{sub c} = 1, has been determined.
