Abstract

Methods are described herein for assisting with coating (604A) removal. In some approaches, a method (200) for removing a coating (604A) from a coated component (100, 700, 800, 900) is provided. The coated component (100, 700, 800, 900) comprises a substrate (102, 302, 602, 702, 802, 902) with a coating (604A) disposed on the substrate (102, 302, 602, 702, 802, 902). The coating (604A) may have one or more defects therein. The method includes forming a plurality of recesses (314, 414, 614, 714, 814, 914) in the coating (104) that extend from a surface (322, 422) of the coating (104) through one or more layers of the coating (104) to a target layer (320, 420, 720, 820, 920) to produce an etched coating (304, 404, 604B, 704, 804, 904, 604B), and removing the one or more layers of the coating (104) by subjecting the etched coating (304, 404, 604B, 704, 804, 904, 604B) to at least one of a mechanical removal process or a chemical removal process to expose the target layer (320, 420, 720, 820, 920).
