| Abstract: | Features of structure formation and the phase composition of facing alloys based on Fe-Cr-Ni with different silicon contents during plasma deposition in order to improve the wear resistance of low-carbon steels are studied. With a silicon content exceeding 4% a network of silicon oxide SiO2 forms along grain boundaries preventing dendrite development. The materials are strengthened due to formation during facing of silicide inclusions CrSi2 and MoSi0.65.Tula Polytechnic Institute.
