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%.1-7openAccessheat treatmentsboridesrare earthsdiffusionboronArtigo de periódico14210.22533/at.ed.31721422060740000-0002-1423-871Xhttps://orcid.org/0000-0002-1423-871XSem PercentilSem Percentil CiteScore
