Description
Summary:Electrophoretic deposition of the commercially available MgB 2 powder on stainless steel substrates from methanol dispersion medium is reported for the first time. Various deposition parameters such as deposition medium, quantity of powder loading, deposition potential and the time of deposition have been optimized. Films were subjected to heat treatment in flowing argon ambience and excess magnesium powder. Structural, morphological and FTIR studies of the films were carried out. The films are found to be adherent, uniform and with no traces of MgO. Films showed the superconducting transition in the range 38.5–39 K.
