Resumo
Rare-earth elements have been used in the thermochemical treatment of boronizing to enhance boron
diffusion. In order to further investigate the effect of these elements on the process, neodymium-,
samarium-, and gadolinium were utilized for the treatment of AISI 1045 samples carried out at the
temperature of 1173 K for 4 h. The resulting boride layers formed were characterized through optical
microscopy, microhardness test, and X-ray diffraction (XRD). The comparison of the layers showed
that the addition of neodymium increased the depth by 48%, with samarium by 54%, and with
gadolinium by 76%.
