By a method of hybrid physical-chemical vapour deposition (HPCVD) on three metal substrates of stainless steel, copper and niobium, we deposit MgB2 superconducting Elms over 1 mu m thickness. All of them have zero resistance temperatures T-c(0) > 36 K and critical current densities J(c) (10 K, 0 T) > 10(6) A/cm(2). Meanwhile, in the bending test, all the MgB2 superconducting Elms adhere strongly to the metal substrates without peeling off. Therefore, the MgB2 superconducting Elms supplied by the HPCVD method exhibit preferable electrical, magnetic and mechanical properties, and have potential applications in future.
