摘要

The structure and phase composition of ion-carboazotated materials were studied. Based on X-ray structural analysis, the dependence of changes in the crystal lattice parameters and nitrogen concentration in the surface layer on the ion nitriding modes was established. The electrochemical behavior, corrosion resistance, and corrosion-mechanical wear of unhardened and hardened specimens in a conveyor-washing water environment were studied. It was found that the corrosion and wear resistance of steels and cast iron under friction are significantly influenced by the physical and mechanical characteristics of the nitrided layer, namely microhardness, thickness gradient, diffusion layer thickness, surface phase composition, and base microhardness. The results of the experiments show that carbonitriding increases the corrosion resistance of the studied materials in static conditions by 1.09–1.40 times and in dynamic conditions by 1.24–1.91 times, and their wear resistance by 1.7–11.1 times.
