Titanium Deposition on Copper using Additively Manufactured Electrodes by Electric Discharge Coating in DI Water

The electric discharge coating method is a non-traditional technique to coat conductive metallic materials. In recent studies, additively manufactured electrodes such as Ti6Al4V have been employed to apply a coating to the surface of copper using EDC in deionized water. Surface characterization, which was conducted using scanning electron microscopy and X-ray diffraction (XRD) analysis, revealed that a higher percentage of Titanium was present on the surface of the copper when coated with two parameters: 6A and 8A with a 66% duty factor. XRD analysis also demonstrated the presence of Titanium dioxide. Moreover, the results indicated less carbon deposition on the surface of the materials and lower surface roughness. This method is cost-effective compared to traditional coating methods and opens the door to new applications, such as insulation and thermal barrier coatings.
