摘要：
Graphene oxide (GO) was deposited uniformly on the surface of permanent magnet material NdFeB by electrophoretic deposition (EPD). Electrophoretic deposited graphene oxide (EPD-GO) coating was reduced partially after EPD process, owing to the removal of oxygen functional groups. And EPD-GO coating showed excellent adhesion to the NdFeB matrix. According to the results of electrochemical tests, the decrease in corrosion current density and the positive shift in corrosion potential have both demonstrated that EPD-GO coating served as a corrosion inhibitor, protecting NdFeB from NaCl aqueous solution.
