Rotor and stator assemblies that utilize magnetic bearings for supporting the rotor shaft during operation can be suitably used in corrosive environments, such as sour gas. The rotor and stator assemblies include NACE compliant magnetic bearing arrangements for sour gas applications. In one embodiment, a rotor shaft assembly (100) for a magnetic bearing arrangement comprises a rotor shaft (102) formed of a ferromagnetic material comprising a plurality of rotor laminations (104) disposed on the rotor shaft (102); and a barrier layer (106) formed on selected exposed surfaces of the rotor shaft 102, wherein the barrier layer (106) is effective to resist corrosion relative to the surface without the barrier layer (106).
