Claim 12:
13. A method of forming a coated component for a gas turbine engine, the coated component defining a longitudinal direction, the method comprising:
forming a ceramic coating along a surface of a substrate;
forming a plurality of linear slots along the ceramic coating, wherein the plurality of linear slots extend through 80 percent or more of a thickness of the ceramic coating; and
forming a plurality of non-linear slots along the ceramic coating that intersect the plurality of linear slots, the plurality of non-linear slots extending through the ceramic coating to an end point above the surface of the substrate, wherein the plurality of linear slots and the plurality of non-linear slots define radial sectors between adjacent linear slots, each radial sector including a plurality of segments of ceramic coating material, each segment separated from an adjacent segment by one of the plurality of non-linear slots.
