In this work the surface roughness behaviour in the forming of gaseous nitrocarburized layers has been analyzed. Ra values from 0.02 to 1.50 μm. has been considered. Obtained results prove a minor influence on layer thickness. A little increase of Ra has been observed. The abrasive wear resistance of nitrocarburized specimens was researched. The carbonitride ε is the only constituent in the about 6 μm thickness layers that have been carried out in this work. The tests revealed a minor wear resistance of the external part in the layers. This way, the external zone is less effective to wear phenomena than the internal. The specimens with small roughness parameters values show a higher poor wear resistance zone.
