Abstract By a method of hybrid physical-chemical vapour deposition (HPCVD) on three metal substrates of stainless steel, copper and niobium, we deposit MgB2 superconducting films over 1μm thickness. All of them have zero resistance temperatures TC(0)>36K and critical current densities JC (10K, 0T)
>106A/cm2. Meanwhile, in the bending test, all the MgB2 superconducting films adhere strongly to the metal substrates without peeling off. Therefore, the MgB2 superconducting films supplied by the HPCVD method exhibit preferable electrical, magnetic and mechanical properties, and have potential
applications in future.
