Abstract The corrosion behavior of HSn70-1copper alloy in sulfate-reducing bacteria (SRB) containing medium in the absence and presence of a static magnetic field (SMF) respectively was investigated by means of weight loss method, electrochemical measurement and surface analysis method. The results showed that the corrosion weight loss and the corrosion current density of the alloy was higher in the inoculated SRB medium in the absence of SMF rather than those in the presence of SMF. Thus the presence of a SMF can suppress effectively the corrosion of copper alloy. The results of SEM/EDS, XRD and XPS analysis showed that in the inoculated SRB medium a compact and uniform film formed on the surface of copper alloy in the presence of SMF, the corrosion products were cuprous sulfide; however in the absence of SMF the formed corrosion product on the alloy was loose and consisted of cupric sulfide. In fact the compact corrosion scale of cuprous sulfide could effectively suppress the SRB induced corrosion of copper alloy.
