Bi2Sr2CaCu2O x thick films was fabricated by laminar flow thermal spray onto various types of substrates, such as; stainless steels and nickel‐based alloys with buffer layers of yttrium stabilized zirconia (YSZ) and silver. After annealing the specimens, it was observed that the both buffer layer materials can effectively prevent the reaction between the oxide superconductor and the substrate, although the oxide superconductor sometimes peeled off from the YSZ layer. The highest critical temperature so far is 88 K by annealing the thick film in the low oxygen pressure atmosphere. This process preparing the thick film will be applied to the fabrication of a magnetic shield vessel for use in the biomagnetic measurements.
