Abstract
A process for applying a vertically cracked ceramic thermal barrier coating to a machine component includes a.) applying a plurality of layers of the ceramic thermal barrier coating on the component, utilizing a nozzle at a first distance from the component; b.) applying an additional sacrificial outer layer of the ceramic thermal barrier coating of the same chemical composition as the plurality of layers on the component, with the nozzle at a second distance from the component, greater than the first distance; and c) removing at least some of the outer layers to achieve thickness and surface roughness specifications.
