Abstract
In a method for processing a turbomachine airfoil element, the airfoil element comprises a metallic substrate having: an airfoil extending from a first end to a second end; and a cooling passageway system extending through the airfoil. The method comprises: applying an external vibration to an area of the airfoil element targeting internal fouling of the cooling passageway system; flushing the cooling passageway system; and imaging the cooling passageway system.
