Abstract
We have analyzed the structure and composition of eutectic composite dispersion-hardened materials of the Fe–Mn–C–B system alloyed by Si, Ni, and Cr. A multi-criteria evaluation of the choice of a material characterized by the highest wear resistance under different friction conditions and with different riders is presented. We have evaluated developed PMI-12, PMI-13, PMI-14, and PMI-15-type materials and quantity-produced PG–SR3, PG–10N–01 materials of the Ni–Cr–B–Si system, which are known for many years in the world market. For the analysis, we have used the compromise solution determination method and the undifferentiation interval method that enter the evolution system of multi-criteria analysis.
