A gas turbine engine article includes a substrate (80) and a bond coating (82; 182) that covers at least a portion of the substrate (80) with a step (86; 186) formed in at least one of the substrate (80) and the bond coating (82; 182). A thermally insulating topcoat (84; 184) is disposed on the bond coating (82; 182). The thermally insulating topcoat (84; 184) includes a first topcoat portion (92) separated by at least one fault (98; 198) that extends through the thermally insulating topcoat (84; 184) from a second topcoat portion (96).
