Testing and characterization of balistic coatings by Elektro Spark Deposition

Steel materials used for mechanical and construction purposes can exhibit high corrosion and abrasion resistance with coatings made on their surfaces. In this study, the surface of AISI 1008 steel pad substrate was coated with Tungsten (W), Tungsten Carbide (WC) and Alloy Steel electrodes at different volts and frequencies by Electro-Spark Deposition (ESD) method. The ESD method is a small arc welding method that allows metal deposits on the surface, thanks to the common methods for the surface of metallic materials, as well as the plasma that brings about a better bond and good adhesion of the electric currents. In this study, the steel samples were coated with Tungsten (W), Tungsten Carbide (WC) and Alloy Steel electrodes, and the precoating and post-coating hardnesses and coating layer thicknesses of the samples were examined and the existing coatings were examined for ballistic purposes. As a result of the analyzes made, hardness was obtained about twice as much as the main material in the coating with the alloy steel electrode, about three times in the coating with the tungsten electrode and about five times as much as the main material in the coating with the tungsten carbide electrode.
