This paper studies the coatings deposited on a 65G steel substrate by electric arc metallization using 30KhGSA wire. The properties of obtained at 30 V, 40 V and 45 are discussed, including their microstructure, porosity, microhardness, coefficient friction corrosion resistance. experiments showed that possess layered structure formed sequential deposition metal microdroplets. It was found increase in voltage favors decrease layer density, microhardness improvement wear resistance At maximum (45 V), there optimum performance characteristics, such as minimal porosity (1.36%), high (305 HV) improved main defects coatings, pores oxide inclusions, which during sputtering process depend kinetic energy microdroplets, were identified. These affect mechanical protective coatings.
