Modeling the Nitriding of Steel by Compound Layer Growth Model

CODEN: MPCACD

Abstract

The effort to simulate the nitriding process has been ongoing for the last 20 years. Most of the work has been done to simulate the nitriding process of pure iron. In the present work, the compound layer growth model has been developed to simulate the nitriding process of AISI 4140 steel. In this paper, the fundamentals of the model are presented and discussed including the kinetics of compound layer growth and the determination of the boundary conditions. The experimental verification of the model is also presented. It proves the concept of utilizing the compound layer growth model in other steels. The nitriding process of various steels can thus be modeled and predicted in the future.
