The Research of Technological Properties of Coatings Sprayed with Electric Arc Spray

Abstract

The paper presents dry friction test results of two experimentalSTEIN-MESYFIL wires with different chemical composition.Thermal spray coatings properties depend on the chemical compositionand the technological parameters of the spraying. Eachcoating was sprayed in the three different modes. The microhardness,porosity, oxides were analyzed in the coatings morphology.Dry friction wear was assessed in the mass loss of the coatings.
