ABSTRACT:
A rotary blower rotor includes a rotor body having a corrosion-resistant coating covering the rotor body. An abradable coating covers at least a portion of the corrosion-resistant coating for providing an essentially zero operating clearance for increasing a volumetric efficiency of the rotary blower. A rotary blower including a rotor with a corrosion-resistant coating is also provided.
