compact monolayer is most wanted in plasma surface treatments of steels. This phase can be
obtained by the inclusion of carbon species in the plasma. In this work, we present a
systematic study of the carbon influence on the compound layer in an AISI H13 tool steel
by pulsed plasma nitrocarburizing process with different gaseous ratios (0% [CH4]/
[N2 þ CH4 þ H2] 4%). The plasma treatment was carried out for 5 h at 575 8C. The microstructure and phase composition of the modified layers were studied by scanning electron
microscopy and X-ray diffraction, respectively. X-Ray photoelectron spectroscopy was used to
measure the relative concentration of carbon and nitrogen on the surface. The hardening
profile induced by the nitrocarburized process is also reported.
