Abstract:
A method for removing a damaged substrate layer that is present within a substrate region beneath an environmental coating on a surface of a component, the method comprising the steps of:evaluating the component to assess the depth of the damaged substrate layer; sensing a plurality of points over an outer surface of the component to determine a three-dimensional outer surface profile thereof; establishing a three-dimensional grinding profile beneath the outer surface profile based on the depth of the damaged substrate layer beneath the outer surface profile; grinding the component along the grinding profile such that the damaged substrate layer is substantially removed without significantly removing an undamaged region of the substrate beneath the damaged substrate layer, the grinding step generating a ground surface on the component; and then sensing the ground surface at locations corresponding to at least some of the plurality of points over the outer surface of the component to verify removal of the damaged substrate layer.
