Abstract
A manufacturing method is provided. During this method, a preform component for a turbine engine is provided that includes a substrate. A meter section of a cooling aperture is formed in the substrate. An external coating is applied over the substrate. At least a portion of the substrate and the external coating is scanned with an imaging system to provide scan data indicative of an internal structure of the portion of the substrate and the external coating. A diffuser section of the cooling aperture is formed in the external coating and the substrate based on the scan data.
Claims20
A method involving an imaging system, comprising:
- providing a component for a turbine engine, the component including a substrate, an external coating over the substrate, a meter section of a cooling aperture formed in the substrate and a diffuser section of the cooling aperture formed in the external coating and the substrate;
- scanning at least a portion of the component using the imaging system to provide scan data indicative of an internal structure of the portion of the component, wherein the portion of the component includes the meter section;
- and
- performing an operation based on the scan data, the operation comprising evaluating an alignment between the diffuser section and the meter section based on the scan data.
An inspection method, comprising:
- providing a component of a turbine engine, the component comprising a plurality of cooling apertures, a first of the plurality of cooling apertures including a diffuser section and a meter section;
- scanning at least a portion of the component with an imaging system to provide scan data indicative of an internal structure of the portion of the component;
- and
- processing the scan data to evaluate alignment between the diffuser section and the meter section.
