An Approach for Analyzing the Growth Kinetics of Fe2B Phase on AISI 1018 Steel

A simulation of the growth kinetics of Fe2B iron boride forming on AISI 1018 carbon steel was done on the basis of a kinetic model. This model including the effect of the incubation time during the formation of Fe2B iron boride, was applied in order to evaluate the kinetic constant at the ( Fe,B I Fe) interface, the Fe2B layer thickness and the mass gain depending on the paste-bonding parameters such as time, temperature and boron potential reflected by the corresponding value of the surface boron content. The simulation results were found to be in a good agreement with the experimental data derived from the literature.
