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%.
