Abstract: MoandCions extracted from a metal vapor vacuum arc ion source were implanted into the surface of die steel (H13) to compare the wear resistance mechanisms of the implanted samples, respectively. The concentration depth profiles of implanted ions were measured using Rutherford backscattering spectroscopy and calculated by a code called TRIDYN. The structures of the implanted steel were observed by X-ray photoelectron spectroscopy and grazing-angle X-ray diffraction, respectively. It was found that the conventional heat-treated H13 steel could not be further hardened by the subsequent implantedCions, and the thickness of the implanted layer was not an important factor for theMoandCion implantation to improve the wear resistance of the H13 steel.Moion implantation could obviously improve the wear resistance of the steel at an extraction voltage of 48 kV and a dose of5 × 1017cm-2due to formation of a modification layer of little oxidation withMo2Cin the implanted surface.
