This paper presents a study of the effect of high voltage electrospark deposition (ESD) using tungsten electrode on the carbon steel. The layers were investigated with metallographic methods. Microscopic examination was carried out to examine the structure of formed layers. Image analysis methods were used to observe the cross-section of the layer. Scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDX) analysis was conducted to characterize the microstructure and composition of the coating. Micro-hardness tests were carried out to evaluate the mechanical properties of coating on carbon steel. The results of investigations showed that there is a possibility of obtaining the satisfying quality superficial layer on the carbon steel C45 using tungsten electrode.Keywords: Electrospark deposition (ESD), surface layer, microhardness, EDM, electrical-discharge alloying
