Superconducting coatings of MgB2 prepared by electrophoretic deposition

Abstract

The electrophoretic deposition technique was applied for the production of MgB(2) superconducting coatings on various substrates, by using a suspension of MgB(2) 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).

Transformation of MgB2 powder into superconducting film via electrophoretic deposition technique

“…lower than 0.5 cm, which resulted in maximum thickness. The consistent efforts were made by Ochsenkühn-Petropoulou et al [19] concluded that at for 0.8 cm electrode distance in acetone, the current density in the electrophoretic bath is very high, which may cause the inflexion of acetone at applied voltage of 500 V. However, no inflexion of methanol bath is observed as applied potential is less i.e. 120 V. Thus distance between electrodes is optimized to 0.5 cm, to obtain thick MgB 2 films from the optimized bath.…”

“…Thick films have great potential applications in magnetic shielding and high power antenna [6]. In recent years different techniques, such as screening printing [2,7], sol-gel [8], solution spray [9], partial melting technique [10], electrocrystallization [11][12][13], and electrophoretic deposition (EPD) have been used for the fabrication of thick films of MgB 2 [14][15][16][17][18][19] and high-T c superconductors [20,21]. The electrophoretic deposition is a very simple and rapid technique, which enables single or double-sided coatings on desired substrates with any shape.…”
