Abstract

The influence of rare-earth metals adsorbed in the surface of the metallic material subject to thermochemical processing as well as of those pre-added in the material matrix on the kinetics of layers growth is presented in the technical literature. It is generally concluded that the presence of rare earths is accelerating the kinetics of layer growth.
