Investigation of the effect of ion implantation on tribotechnical characteristics of cast iron

The article presents studies of the tribotechnical characteristics of cast iron after various types of hardening. Samples (chemical composition of the obtained cast iron: C - 3.06%; Cu - 2.38%; Si - 2.2%; Mn - 0.75%; Cr - 0.32%; P - 0.18%; Ni - 0.1%; S - 0.05%, and Brinell hardness - 1.97-2.07 GPa) for wear tests were previously implanted with N+, B+, C+ ions, as well as TiN sputtering and carbonitration. The research was carried out on a friction machine making reciprocating motion along the counterbody. In the course of the work, the main tribotechnical characteristics of cast iron samples were analyzed in the initial state, after implantation, carbonitration and deposition of TiN. The surface morphology of cast iron samples was also studied using a scanning electron microscope in the initial state and after the above types of processing.
