| The paper presents the results of an X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) study of chemical and phase composition of the friction surfaces Fe–Mn–C–B–Si–Ni–Cr hardfacing coatings. The alloy was used as a core mixture to produce flux-cored wire of 2.4 mm in diameter. The coating was deposited by gas metal arc welding using CO2 as a shielding gas. The tribological examination was conducted in a ball on disk system with a load of 20 N under dry friction conditions. A XPS were used to examine the structures on the friction surface and depend on depth 5, 10, 15, 20, 50, 100, 200, and 6000 nm. The segregation of C, B, and Si atoms was observed in the process of the friction. The presence of compounds such as oxides (B2O3, SiO2, Cr2O3), carbides (Fe3C, Cr7C3), and borides (FeB, Fe2B) was detected on the surface and in the subsurface layer of the Fe–Mn–C–B–Si–Ni–Cr coating. The formation of these structures increases the wear resistance of composite coatings |
