Abstract


The paper presents coatings obtained using two different stainless steel (AISI 316) and marine bronze (CuAl8) wires sprayed with electric arc spraying. Substrate: mild steel S235J2 (LST EN 10025: 2004). Arc spray equipment – “EuTronic Arc Spray 4” with an additional power source. The main task was to select optimal technological spraying process and obtain coatings which possess the best mechanical, physical, tribological properties that meet the requirements of the specific requirements in service coatings. The microhardness, elastic modulus, and morphology was examined. Dry friction wear was assessed in the mass loss of the coatings. The results of tribological coatings properties were assessed in determining the mass lost.
