Abstract:
A method is provided for manufacturing a component. The method includes connecting a component comprising an internal passage and formed by an additive manufacturing process to a power supply, the component functioning as an anode, connecting a cathode to the power supply, the cathode being disposed in an electrolyte solution, the cathode being positioned externally to the internal passage of the component, contacting the internal passage of the component with the electrolyte solution, and using the power supply, applying a potential difference and current flow between the component and the cathode.
