| Abstract: | The electrophoretic deposition technique was applied for the production of MgB2 superconducting coatings on various substrates, by using a suspension of MgB2 superconducting powder in an organic solvent. The main parameters that affect the deposition rate of the process and the quality of the coatings produced, such as the initial concentration of the suspension, the applied voltage and the distance between the electrodes, were investigated and optimized. The coatings produced were characterized and investigated for possible interaction between the substrate and the deposited superconductor by X-ray diffraction. The superconducting properties were measured by magnetic susceptibility (superconducting quantum interference device). |
