Abstract
H13 steel samples were implanted with tungsten and the improvement in surface mechanical properties was investigated. The tungsten ion implantation was done using a metal vapor vacuum arc (MEVVA) ion source, with an ion current density of 15 μA cm −2. The implantation of tungsten showed a superior wear resistance surface. The relationship between surface mechanical property and microstructure for the tungsten-implanted samples was characterized by Rutherford backscattering spectroscopy (RBS), grazing-angle X-ray diffraction (GAXRD) and X-ray photoelectron spectroscopy (XPS). The tungsten carbides and tungsten oxides were observed in the doped region. The experimental results have shown that the formation of WC and WO 3 improved the wear resistance of H13 steel.
