In addition, PIII was used for simultaneous implantation of carbon and nitrogen into H13 steel at 380 °C. Treated and untreated samples were studied by wear-friction testing, microhardness measurement, atomic force microscopy and glancing angle X-ray diffraction (XRD) diagnosis. Experimental results indicated that the hardness and wear resistance were improved by increasing the PIII treatment temperature, whereas the presence of C ions does the opposite. It is explained by a nitride formation and a lattice expansion between 1.7 and 2.23%. © 2007 Elsevier B.V. All rights reserved.Article10.1016/j.jmatprotec.2007.02.014
