Comparative studies of the microstructure, porosity and hardness of the surface layer of a low-carbon steel are performed after nitrocarburizing by traditional single-cycle and novel multi-cycle treatments. The sizes and the content of pores in the surface layer are determined, the profile of the variation of microhardness over its thickness is plotted, and an x-ray diffraction analysis is performed. It is recommended to use multi-cycle nitrocarburizing for surface treatment of parts from low-carbon steels in order to raise the operating characteristics of the parts.
