    Abstract: A thermal barrier coating (18) having a less dense bottom layer (20) and a more dense top layer (22) with a plurality of segmentation gaps (28) formed in the top layer to provide thermal strain relief. The top layer may be at least 95% of the theoretical density in order to minimize the densification effect during long term operation, and the bottom layer may be no more than 95% of the theoretical density in order to optimize the thermal insulation and strain tolerance properties of the coating. The gaps are formed by a laser engraving process controlled to limit the size of the surface opening to no more than 50 microns in order to limit the aerodynamic impact of the gaps for combustion turbine applications. The laser engraving process is also controlled to form a generally U-shaped bottom geometry (54) in the gaps in order to minimize the stress concentration effect.

    Abstract: A method of forming a cooling feature (28) on a surface (14) of a substrate (12) to protect the substrate from a high temperature environment. The cooling feature is formed by first depositing a layer of a masking material (16) such as epoxy resin on the surface of the substrate. A pattern of voids (18) is then cut into the masking material by a laser engraving process which exposes portions of the substrate surface. A plurality of supports (20) are then formed by electroplating a support material onto the exposed portions of the substrate surface. A layer of material is then electroplated onto the supports and over the masking material to form a skin that interconnects the supports. Finally, the remaining portions of the masking material are removed to form a plurality of cooling channels (26) defined by the supports, skin and substrate surface. An additional layer of material (42) may be deposited onto a top surface (50) of the cooling feature to provide additional thermal and/or mechanical protection.
