Segregation of atoms of the eutectic alloys Fe–Mn–C–B–Si–Ni–Cr at friction wear

Wear resistance of eutectic alloys based on the Fe–Mn–C–B–Si–Ni–Cr system was studied. The surface alloys were obtained by plasma surfacing of steel disks previously prepared powder alloys. Atomic segregation in the eutectic coatings due to wear was studied by Auger- and mass-spectroscopy. An increased content of C, B and Si at a friction surface was revealed. Oxygen diffusion from the atmosphere into the coating was not detected.
