Resumen:
The influence of microstructure on the corrosion behavior of pulsed plasma nitrocarburized AISI H13 tool
steel in NaCl 0.9 wt/V % solution is reported. The samples were prepared with different nitrocarburizing
treatment times using a constant [CH4/H2+N2] gaseous mixture by a DC pulsed plasma system. The
microstructure of the nitrocarburized layers was analyzed by scanning electron microscopy (SEM), X-ray
photoelectron spectroscopy (XPS) and X-ray diffraction. The corrosion behavior was evaluated by
potentiodynamic polarization experiments. The nitrocarburizing process considerably improves the
corrosion resistance of the material in a NaCl environment as compared to the untreated H13 steel. The
modified surface layer mainly consisting of ¦Å-Fe2¨C3(C,N) and ¦Ã¡ä-Fe4N phases confers this outstanding
behavior. The corrosion resistance dependence on specific nitrocarburizing processes is reported and the role
of the surface porosity is discussed.
