Abstract: Dimensional analysis is presented as a powerful tool in the study of the paste boriding process. In particular, a dimensional method is used to study the growth kinetics of the boride layers FeB and Fe2B. Experiments were performed in AISI 1045 steel and AISI M2 steel, to test the suggested model. Results indicate that the growth of boride layers obeys power laws of the form γ = αχβ, where the α and β constants are a function of the material and the interface of interest.

Keywords: dimensional analysis; growth kinetics; paste boriding; boride layers; microstructure; material properties; heat treatment; iron boride; steel surface.
