Preparation of MgB2 Films by Directly Electrophoretic Depositing MgB2 Powder on Ti Substrates

摘要：

　　MgB2 powder was fabricated by sintering the mixture of pure Mg and B powder with atomic ratio of Mg: B=l∶2.The magnetic property of the powder indicated that it was superconducting and its critical transition temperature was 39K.Titanium based MgB2 films were obtained by electrophoretic deposition method using Ni sheet as anode and titanium tapes as cathode.The films were annealed at 500℃ for 2 hours, subjected to argon-hydrogen (95%Ar+5%H2) gas flow.The results of X-ray diffraction (XRD) analysis showed that the composition of the film was mainly MgB2.The observation under scanning electron microscopy (SEM) showed that the film of MgB2 was uniform and dense.The electrical resistivity of double-side MgB2 film was about 5.280× 10-8Ω/m.
