N2 - In this study, the wear behavior of AISI 1018 borided steel is characterized. The boriding thermochemical treatment was carried out at 1273 K for 6 h, and different thicknesses of the boriding agent surrounding the samples were examined. The layer structure was composed of FeB and Fe2B layers.The tribological properties at the surface of borided and unborided steel were evaluated employing the ball-on-flat method with sliding reciprocating wear tests, using an Al2O3 ball as the counterpart. The applied load and the sliding speed remained constant at 5 N and 5 mm/s, respectively, with sliding distances of 81 m, 108 m and 135 m.The coefficients of friction (CoFs) on the boride layers from the sliding reciprocating wear tests for dry and lubricated conditions were evaluated. The CoFs are independent of the boriding potential expressed as the powder thickness. Surface wear for longer sliding distances in lubricated conditions was neglected; there was no difference between the wear track and the original surface roughness in the profilometer results. The wear scar diameter and the worn surfaces of borided and unborided steels in both experimental conditions were characterized by SEM to understand the wear mechanisms.
