Cross-Section
Definition
An exposed plane across a coating stack that reveals relationships between layers. 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 prepared coating section can reveal one layer beneath another without showing that their chemical compositions are identical.
A mixed bulk result may not represent one layer. Comparison needs compatible preparation, sampling and analytical resolution.
