Selected properties of electro-spark deposition on carbon steel using the Alloy 400 electrodes

摘要

The paper presents a study of surface layers produced by electro-spark deposition (ESD) using Alloy 400 electrode on the carbon steel. In the electro-spark deposition process, the electrode is the anode and the work piece is the cathode. 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. For diffusion observations, ESD analyzes were performed on the cross-section of the produced layer. Scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDX) analysis was conducjed to characterize the microstructure and composition of the coating. The results of investigations showed that there is a possibility of obtaining the satisfying quality superficial layer on the carbon steel using Alloy 400 electrode.
