Abstract: A refurbishing method, refurbishing apparatus and refurbished article are provided. The refurbishing method includes accessing a plurality of rotatable components attached to a turbine assembly, the turbine assembly being a portion of a turbomachine, providing a predetermined volume of a buffered electrolytic solution in an electro-polishing tank, coupling the plurality of rotatable components to a power supply, immersing an immersion portion of at least one of the plurality of rotatable components in the buffered electrolytic solution, passing an electrical energy through the immersion portion of at least one of the plurality of rotatable components while the immersion portion is immersed in the buffered electrolytic solution, wherein an electrical flux to the immersion portion electro-polishes the immersion portion, separating the immersion portion from the buffered electrolytic solution, and applying a corrosion inhibitor to the plurality of rotatable components.
