- © 2020 Elsevier B.V.Carbon nanomaterials (CNs) were deposited on borided AISI O1 steel by chemical vapor deposition. The deposit, characterized by scanning electron microscopy and X-ray diffraction, presents CNs such as carbon nanotubes, as well as cementite and amorphous carbon. The tribological effects of friction and wear under dry conditions were analyzed with a ball-on-disk with a tungsten carbide (CW) ball and roughness meter. The results show that the coefficient of friction considerably decreases and stabilizes to ~ 0.24 for the sample with CNs. It also is concluded that CNs act as a protective coating that prevents the surface of the borided steel from wear.
