Abstrakt: Electric arc thermal deposition, unlike other methods (D-gun, plasma spraying, flame spraying, laser surfaces alloying), induce reduced structural changes in the base material due to lower temperatures in the deposition process. The samples analyzed in this paper were obtained by electric arc deposition with the Smart Arc 350 installation from Sulzer Metco. This paper presents structural and morphological analyzes of the obtained coatings and also analyses the adherence of the coating to a 18MnCr11 steel alloy base material. For highlighting the results electron microscopy analyses were made with the QUANTA 200 3D DUAL BEAM electron microscope. The XRD analyses helped to establish the phases and constituents of the electric arc deposited coating. The adherence of the layer was assessed using the scratch method with the UMTR 2M-CTR micro tribometer. [ABSTRACT FROM AUTHOR]
