Surface modification of a ferritic ductile iron through plasma nitriding

This text describes the plasma nitriding of a ductile iron, to increase surface hardness and improve its wear behavior. A ferritic iron was used processed with gases (N2 + H2) for 5 hours in treatment chamber built at UNAM Physics Institute. The treated samples were characterized using scanning electron microscopy, atomic force microhardness X-ray diffraction. presence Fe-N compounds corroborated on material. Modifications morphology 30% also obtained.
