Layer-Specific Analysis
Definition
Measurement designed to represent an identified layer, with neighbouring contributions assessed. A prepared cross-section can reveal layer order, thickness and relationships. Layer-specific measurements should consider contributions from adjacent coatings and the substrate.
- Context
- Coating examination
For example, a measurement intended for one thin coating layer can include neighbouring material if its sampling region extends across the boundary.
A mixed bulk result may not represent one layer. Comparison needs compatible preparation, sampling and analytical resolution.
