MgB2, due to its high transition temperature of ~40K and absence of weak links between grains, is a candidate material for superconducting radio-frequency (RF) cavities for future particle accelerators. Peking University has developed a HPCVD method for MgB2 fabricating on metallic substrates. We have grown MgB2 films on the substrates of Cu, Nb and Mo successfully. Recently, for better quality of MgB2 film, we tried to fabricate MgB2 film on Cu substrate which was coated a thin film of Mo on the surface. We also tried to obtain the large-area MgB2 film (2-inches in diameter) on metallic substrate with good uniform for RF measurement. The method and results of recent experiments will be presented.
