Abstract
A process of preventing spallation for a geometrically segmented thermally insulating top coat on an article, the process including forming a surface feature with a surface feature tip on a surface of the article; disposing the thermally insulating topcoat over the surface feature; and forming segmented portions that are separated by faults extending through the thermally insulating topcoat from the surface feature tip.

A process of preventing spallation for a geometrically segmented thermally insulating top coat on an article, the process comprising:
- forming a surface feature with a surface feature tip on a surface of the article;
- disposing the thermally insulating topcoat over the surface feature;
- and
- forming segmented portions that are separated by faults extending through the thermally insulating topcoat from the surface feature tip.
A geometrically segmented thermally insulating top coat on an article comprising:
- a surface feature shaped as a pyramid with a surface feature tip, the surface feature formed on a surface of the article;
- the thermally insulating topcoat being disposed over the surface feature;
- and
- segmented portions that are separated by faults extending through the thermally insulating topcoat from the surface feature tip.
A process of interrupting spallation for geometrically segmented coatings on a gas turbine engine component comprising:
- the gas turbine engine component having a surface;
- forming a surface feature with a surface feature tip on the surface of the gas turbine engine component;
- disposing the thermally insulating topcoat over the surface feature;
- and
- forming segmented portions that are separated by faults extending through the thermally insulating topcoat from the surface feature tip.
